Intelligent cascade quantum imaging detection system

Abstract

An intelligent cascade quantum imaging detection system is characterized by comprising a control and image calculation module, a dual-band laser, a three-dimensional imaging laser radar optical system and an associated quantum imaging optical system. The device comprises two independent working modes of large-view-field scene scanning monitoring and small-view-field target high-resolution quantum imaging, the large-view-field scene scanning monitoring mode carries out large-view-field scanning monitoring imaging, scene three-dimensional point cloud data is obtained, and target automatic detection and recognition are carried out; after a sensitive target is found, a small-view-field target high-resolution quantum imaging mode is guided to aim at the area for high-resolution quantum imaging, and intelligent recognition and analysis of the target are achieved through a high-resolution imaging result. According to the invention, large-view-field scene scanning monitoring and small-view-field target high-resolution quantum imaging capabilities in a complex environment can be greatly improved.

Description

technical field [0001] The invention belongs to the field of optical imaging, in particular to an intelligent cascaded quantum imaging detection system that takes into account the discovery of large-field surveillance targets and high-resolution imaging of small-field targets in complex environments. Background technique [0002] Correlated quantum imaging is a staring imaging technology that requires a series of independent random measurements on the scene, and obtains images through computational reconstruction. The number of independent random measurements required is proportional to the total pixel size to be resolved and the complexity of the target. When the laser repetition rate is limited, high resolution and large imaging field of view are a couple of coupling contradictions. In addition, according to the lidar distance equation, it can be seen that as the staring field of view increases, the operating range of the system decreases rapidly. In summary, from the per...
