Single photon three-dimensional imaging system based on cross strip anode detector

Abstract

The embodiment of the invention discloses a single photon three-dimensional imaging system based on a cross strip anode detector, which comprises a laser transmitting module for generating laser pulses and using the laser pulses to perform uniform lighting on a target, an optical receiving module for receiving the light when teh target reflects the laser pulses to further perform imaging on the target, a detector module for receiving photon signals imaged by the optical receiving module, recording the two-dimensional position of the photon signals and recording the flight time when the photonsignals are transmitted from the laser transmitting module and reflected to fall on the detector module, and an upper computer imaging software module for receiving electric signals outputted by the detector module and performing analytic imaging on the electric signals. The single photon three-dimensional imaging system based on the cross strip anode detector can make full use of the advantages of the cross strip anode detector in the aspect of low light detection and achieve high-spatial resolution three-dimensional imaging.

Description

technical field [0001] The invention relates to the technical field of laser three-dimensional imaging, in particular to a single-photon three-dimensional imaging system based on a cross-strip anode detector. Background technique [0002] The area array laser 3D imaging system obtains the depth information of the target by measuring the photon flight time, obtains the two-dimensional position information of the target through the position sensitivity of the detector, and combines the depth information with the two-dimensional position information to obtain the three-dimensional information of the target . Compared with the single-point scanning 3D imaging system, the area array laser 3D imaging system reduces the mechanical scanning device, thereby reducing the volume and complexity of the 3D imaging system and the resulting errors. The single-photon 3D imaging system can work under the signal intensity of photon level, which is an important development direction of the tra...
