What is the principle of high-speed camera?

There are many kinds of cameras, and the basic principle of their work is the same: converting optical image signals into electrical signals for storage or transmission. When we shoot an object, the light reflected by the object is collected by the camera lens and focused on the light receiving surface of the camera device (such as the target surface of the camera tube), and then the light is converted into electric energy by the camera device, and a "video signal" is obtained. The photoelectric signal is very weak, so it needs to be amplified by pre-amplifier circuit and then processed and adjusted by various circuits. The final standard signal can be sent to video recorders and other recording media for recording, or spread through a propagation system, or sent to a monitor for display.

High-speed cameras can quickly sample high-speed targets many times in a short time. When they are shown at normal speed, the recorded target changes will appear clearly and slowly in front of our eyes. High-speed camera technology has outstanding advantages such as real-time capture of targets, rapid recording of images, instant playback, and intuitive and clear images.

The high-speed moving target is irradiated by natural light or artificial auxiliary illumination to generate reflected light, or the moving target itself emits light, and this light passes through the imaging objective of the high-speed imaging system. After being imaged 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 will respond quickly to the target image on the image sensing surface, that is, according to the light energy distribution of the target image on the image sensing surface, charge packets with response sizes are generated at each sampling point, that is, pixel points, to complete the photoelectric conversion of the image. Each charge packet with image information is quickly transferred to the readout register. After signal processing, the read signal is transmitted to the computer, which reads, displays and interprets the image and outputs the result. Therefore, a complete high-speed imaging system consists of optical imaging, photoelectric imaging, signal transmission, control, image storage and processing.

High-speed cameras are favored by photographers, so what role does it play in daily life?

High-speed cameras are generally used to photograph the flight trajectory of bullets or shells, or high-speed mechanical instruments. They are used in other scientific experiments, mainly for scientific research, and are hardly needed in daily life.

Generally, the experiment of studying supersonic gas jet needs high-definition high-speed camera to shoot, and the memory is large, so the domestic high-speed camera is fully competent.

The high-speed camera needs to be used with the control computer. The control software of high-speed camera is installed in the control computer and connected with the high-speed camera through gigabit network cable, which can realize the post-processing work of high-speed camera operation control, real-time viewing of video images, data download, video format conversion and so on.

When we are outdoors or unable to connect to the computer, we can choose LCD viewfinder and control handle instead of controlling the computer.

The memory size in the configuration parameters of high-speed camera is an important parameter to measure the recording time of a single shot. Memory is not used to store data for a long time, but to download the data in the memory of high-speed camera to the computer for storage after shooting.

High-speed cameras are different from ordinary cameras. The main purpose of high-speed camera is to capture the moment of events, but it cannot be used for long-term recording. We choose different trigger methods to capture instantaneous images that are difficult for human eyes to capture.

To choose a suitable high-speed camera, we usually need to know what the shooting application is, such as the shooting space range and the moving speed of the subject, so as to determine how much resolution and frame rate are needed when shooting. At the same time, many factors such as shooting environment will affect the selection of high-speed cameras and accessories needed for shooting.

The price of high-speed cameras is much more expensive than ordinary everyday cameras. If you want to buy a high-speed camera, the usual practice is to make an offer after selecting it according to the actual application. The whole process is as follows: Toilet Toilet Toilet Toilet Toilet Toilet Toilet Toilet Toilet Toilet Toilet Toilet Toilet Toilet Toilet Toilet Toilet Toilet Toilet Dixian (1) is idle.

What is a high-speed camera?

High-speed cameras are widely used in industrial fields. High-speed cameras can capture images and motion processes that are invisible to the naked eye. The observation and analysis of turbulence, fluid velocity, flow field, bubble, boiling and two-phase flow in fluid mechanics can not be separated from the participation of high-speed cameras. Such as shooting the details of the moment when the stone enters the water with a high-speed camera. Through high-speed camera images, researchers can understand the stress of stones under water, and analyze why stones can float on the water several times in a row through fluid dynamics.

MemrecamACS- 1M60 is a new generation of high-speed camera system newly introduced by nac Company of Japan in 20 19, with the maximum 1 1400 pixels. At this full resolution, the frame rate can reach 100000 frames/second, and the highest speed can reach 20000 frames.

MemrecamACS- 1M60 provides the best solution for users' needs: high sensitivity and faster shooting speed.

High-speed camera is a kind of equipment that can shoot moving images with exposure time less than11000 seconds or frame rate greater than 250 frames per second. High-speed cameras are used to record fast-moving objects as photographic images on storage media. After recording, the images stored in the media can be played in slow motion. Early high-speed cameras used film to record high-speed events, but they were completely replaced by electronic devices using charge-coupled devices (CCD) or CMOS active pixel sensors. Usually, more than 65,438+0,000 frames are recorded on DRAM every second, and the scientific research action of studying transient phenomena is slowly played back.
