Description Technical sector [0001] The invention relates to a camera capable of detecting microscopic vibrations, or vibrations of a few microns, in a single-body, or portable, camera, capable of making measurements for civil structures, in the histological field, for sports medicine, for environmental reconnaissance, in chemistry and physics with micrometric measurements. The camera is also able to combine an optoelectronic system with multispectral analysis in a single device and, through a particular filter, it is able to detect the color rendering index, or the color rendering index (CRI in acronym), with detection bands between 400 and 700 nanometers of the vibrations detected in the recovery, with coloring of the same according to the frequencies. The camera according to the result is therefore able to record and evaluate the vibrations of objects, bodies, molecules, cells and everything that needs to analyze the state of vibration.
State of the art [0002] Cameras are currently known for evaluating predictive vibrations on the stability of the systems under observation. Unfortunately, cameras of a known type are not sufficient for microscopic analysis or on nanometric scales. The shooting systems in use compare images in memory to evaluate the deviation between geometric measurements, with measurement fields that do not drop beyond a certain threshold, sufficient for deviations of measures in centimeters or millimeters.
Presentation of the invention [0003] The object of the result is a camera capable of detecting oscillations in the microscopic field and recording them for stability analysis.
[0004] The camera, according to the invention, is a full embedded camera with DSP (Digital Signal Processing) for the processing of images taken in real time, with particular reference to the magnification of luminance and displacement of the image pixels taken, in order to to highlight small movements or even slight changes in luminance. The system is low power and battery operated and this allows you to create intelligent «sensors» capable of making decisions based on what has been taken. The camera for mechanical and electromagnetic vibrations includes an image sensor, such as a wide spectrum CMOS sensor or a CCD, on which a color rendering index filter and a computer equipped with a DSP (Digital Signal Processing) microprocessor are mounted, where the vibrations are displayed on the camera with variations in color and brightness. The camera collects different shots and collects the data of these shots by quickly comparing pixel by pixel the images detected and processed by pyramid-shaped FFT (Fast Fourier Transform) algorithms and made visible on the monitor with the accumulation of vibrations detected by changes in brightness and color . The processed images are then recorded on a memory unit, such as an SD card. The detected images can then be processed with image processing programs. The image sensors used must have a low number of pixels and a large size, to decrease the processing time and have good sensitivity with low lighting. The invention finds application in all cases where microscopic image processing is required, both for constructions, materials and for cells or other systems vibrating mechanically and in electromagnetic vibrations. These and other purposes and advantages of the present invention will be more evident from the following detailed description of a preferred but not exclusive embodiment, with reference to the attached drawings in which the invention is illustrated purely by way of indication and as such not limiting.
List of drawings [0005]

Realization of the invention [0006] The camera for mechanical and electromagnetic vibrations according to the invention comprises an image sensor 1 and motorized lenses, is equipped with a filter for color rendering index 2, and includes a processor 3 with DSP 4 microprocessor ( Digital Signal Processing) for the processing of images taken in real time and processed with the FFT (Fast Fourier Transform) program capable of detecting and increasing brightness and displacements in the image shooting pixels to highlight movements in the order of microns. Image sensor 1 is a CMOS sensor. In another embodiment the image sensor 1 is a CCD sensor. The number of camera sensors can vary from one to five. The relative positions are recorded from the photos recorded in succession by the camera and the movements are colored by means of a filter for the color rendering index 2, that is, the vibrations detected. The calculation operation takes place in this way: on the camera a pre-processing of the frames, or of the images, is carried out using binning masks, typically 4x4, which increase the signal / noise ratio and a fast Fourier analysis is carried out, ie an FFT (Fast Fourier Transform), on each image, once the image is given to the dialogue software present on the computer, that is on the PC. The variations of luminance or of are then compared in real time and for each frame
CH 715 251 A2 displacement of pixel areas. Furthermore, the variations in color, that is chrominance, are assessed both in the case in which monochromatic sensors with acquisition by HSI tunable filter are used and in the case of non-monochromatic sensors, but with multispectral matrix, by varying the reflection angle of the light. The movement of an object in three dimensions involves, in fact, a tiny variation in the angle of reflection of the light. The binning analysis increases the difference in brightness variation, also a vector matrix is applied which better defines the orientation on the X-Y axes of the direction. The principle is as follows: every time a tiny oscillation due to movement occurs, the light reflectance changes, even if only partially in some spectral lines. Sometimes the reflectance also changes according to the scattering phenomenon and in almost all the spectral band. For every difference reported by pixel areas in each frame, an exponential exaltation is introduced, a sort of picking, which allows the examination of the frames in sequence to highlight the movement and make it visible after amplification. It is necessary to see small displacements of the order of a few microns and with a frequency between 0.01 Hz and 500 Hz, a stack image acquisition with fast sampling, typically between 200 and 2000 fps. The invention is furthermore equipped with an auxiliary card, connected to a first display 5 and a second larger touch display 6. The auxiliary card interfaces with a second card 7 equipped with a WI-FI 8 interface, lithium 9, encoder 10 to select the functions and devices for ignition 11. The card 7 has a slot for SD card 12 with connection and recording devices. The card 7 is connected to an infrared module 13 and to a JPEG 14 chamber. The card 7 is then equipped with a multifunction socket 15. During the operation, the recording is performed with the camera with motorized lenses, highlighting with variations in color and light intensity the vibrations recorded and processed. Whenever there is an oscillation due to movement, the reflectance of light changes, even only partially, in some spectral lines. For every difference detected by pixel areas in each frame, or in every shooting image, an elaboration is carried out by FFT in the DSP 4 microprocessor. This allows the examination of the frame in sequence to highlight the shift and make it visible after amplification . To see displacements of the order of a few microns and with a frequency between 0.01 Hz and 500 Hz, there is an acquisition of a series of images with fast sampling between 200 (two hundred) and 2,000 (two thousand) images per second.
[0007] The chamber can be interfaced with a microscope with relative optics at specific magnifications. The purpose of this connection is to monitor vibrations in a micrometric way in biological structures (cells, red and white blood cells). Numerous tests have been carried out which have shown that in different biological states vibrational patterns correspond and, presumably, different biophysical states.
[0008] To increase the sensitivity of the camera according to the invention to small variations, optics capable of enlarging the image, such as telephoto lenses, with a focal length between three hundred millimeters and one thousand two hundred millimeters are used. The camera is then mounted on a stable platform, such as a tripod, and stabilized. Said camera is also equipped, in particular in the case of infrastructure measurements, with a triaxial accelerometer 16 to ensure that the same camera has not undergone vibrational movements or stresses at the time of data acquisition. The use of a vector matrix software then defines with more precision the orientation of the vibrations recorded on the X Y axes. With two cameras according to the invention, positioned for shooting at different angles, or with the aid of a laser positioned at 45 ° with respect to the camera, measurements of displacements and therefore of vibrations can be made along the Z axis. The invention is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept. All the details can then be replaced by other technically equivalent ones without thereby abandoning the protection field enshrined in the claims.
