31 results about "High-speed camera" patented technology

A high-speed camera is a device capable of capturing moving images with exposures of less than 1/1,000 second or frame rates in excess of 250 frames per second. It is used for recording fast-moving objects as photographic images onto a storage medium. After recording, the images stored on the medium can be played back in slow motion. Early high-speed cameras used film to record the high-speed events, but were superseded by entirely electronic devices using either a charge-coupled device (CCD) or a CMOS active pixel sensor, recording, typically, over 1,000 frames per second onto DRAM, to be played back slowly to study the motion for scientific study of transient phenomena.

Fast exposure adjustment system and method for space high speed camera

This invention provides a rapid exposure adjustment system and method for high-speed space cameras, belonging to the field of deep space exploration. Combining camera image grayscale statistics and PIN tube metering technology, it integrates the advantages of two traditional exposure time adjustment methods. This system can meet the needs of rapid exposure time adjustment for high-speed cameras in transiently bright scenes, avoiding overexposure of consecutive images due to transient brightness caused by impacts. Simultaneously, it can achieve fine-tuning of exposure time in scenes with gradually changing targets, ensuring imaging effects on sputtering clouds generated by impacts. This invention implements an exposure time adjustment method that combines fast and slow adjustments, as well as coarse and fine adjustments, effectively guaranteeing imaging effects in complex scenes throughout the entire kinetic energy impact process.

Spectrally and spatially resolving x-ray and particle detection system

ActiveCN115668000BTomographyNon-linear opticsSpatial light modulatorLiquid crystal light valve
The detection system of an x-ray or charged particle imaging system utilizes a high bandgap, direct conversion x-ray detection material. The signal of the x-ray / charged particle projection is recorded in a spatial light modulator, for example a liquid crystal (LC) light valve. The light valve is then read out by a polarized light optical microscope and a high speed camera. The camera is used to track the halo in the light valve to resolve its intensity and correlate it to the intensity of the incoming x-ray photons or charged particles. This allows for a spatially resolved imaging with an x-ray and / or charged particle spectrometer.

The single-mirror coaxial schlieren imaging method for observing vortex structure in a shock tube belongs to the technical field of fluid flow experiment test, and relates to a single-mirror coaxial schlieren imaging method for observing vortex structure in a shock tube. The method integrates a point light source and a blade to construct an integrated coaxial light source, and uses a schlieren mirror, a shock tube and a high-speed camera to build a single-mirror coaxial schlieren imaging system. In the system, the incident light of the point light source is reflected by the schlieren mirror, passes through the flow field in the shock tube and is focused on the tip of the blade. The blade is used to interfere with the focal point. Because the airflow density in the shock tube is different, the refractive index of the light is different, different schlieren gray images with different light and dark degrees are formed, and the high-speed camera is used to record the change of the vortex structure in the shock tube. The method is easy to debug and saves a lot of experimental debugging time. On the basis of ensuring the light intensity, the influence of ghosting and astigmatism is reduced, and the schlieren imaging of the vortex structure in the shock tube is accurate and clear.
