Benefits of technology

This patented technology allows for precise measurement of various aspects related with an optical sensor called LIDAR (Light Detection And Imaging) or radars systems. It involves controllably shaping lasers into specific shapes before sending them through different parts of the imagery. These modifications help increase their ability to detect objects accurately without being affected by external factors like weather conditions. Additionally, it provides means to measure how well these sensors work over multiple environments simultaneously during operation. Overall, this technology helps optimize the use of space resources while ensuring accurate measurements across all possible scenarios.

Problems solved by technology

This patented technical problem addressed by this patents relates how well an Lidars sensor can detect objects accurately without being affected negatively or positively with other things like sunlight.

Abstract

The invention discloses a GM-APD array camera performance index testing device which comprises a signal generating unit, a laser light source system (including a power supply), a light beam shaping system, a camera obscura, a to-be-tested camera provided with a power supply unit and a data processing unit. The camera obscura provides a dark environment required by the test of the to-be-tested camera, and the light beam shaping system and the to-be-tested camera are placed in the camera obscura. According to the device and the method, main performance indexes such as dark counting rate, detection efficiency, time jitter and post-pulse probability of the GMAPD array camera can be tested, and the actual use performance of a laser radar system can be effectively evaluated according to a resultobtained by the method.
