High-speed camera system principle:
High-speed cameras can quickly and repeatedly sample high-speed targets in a short period of time. When projected at regular speed, the changes in recorded objects are clearly and slowly presented to us. High-speed camera technology has the outstanding advantages of real-time target capture, fast image recording, instant playback, and intuitive image clarity.
High-speed moving targets are reflected by natural light or artificially-assisted illumination to produce reflected light, or the moving target itself emits light, and a portion of this light passes through the imaging objective of a high-speed imaging system. After imaging by the objective lens, it falls on the image sensing surface of the photoelectric imaging device, and the photoelectric device controlled by the driving circuit responds quickly to the target image on the image sensing surface, that is, according to the distribution of the target image light energy on the image sensing surface. Each sampling point, that is, a pixel, generates a charge packet of a response size, and completes photoelectric conversion of the image. Individual charge packets with image information are quickly transferred to the readout registers. The read signal is processed by the signal and transmitted to the computer, and the image is read, displayed and interpreted by the computer, and the result is output. Therefore, a complete high-speed imaging system consists of optical imaging, photoelectric imaging, signal transmission, control, image storage and processing.
A high-speed camera is capable of recording a dynamic image at a very high frequency, because a dynamic image requires several still and consecutive pictures to be played at a certain time speed. A high-speed camera can generally record at a speed of 1000 to 10,000 frames per second. But this has caused each pixel not to be too high or even more than the pixel level of a home digital camera. It also has an amazing storage.
