Abstract

A unit detector optical tomography time division modulation imaging system comprises an image rotating device, a cylindrical mirror and an imaging detector which are sequentially arranged in the front direction of an imaging face of an object to be imaged. The image rotating device is used for rotating an incident object image to generate a rotating image; the cylindrical mirror is used for performing one-dimensional integral amplification on an incident rotating image; and the imaging detector is used for collecting the rotating image after one-dimensional integral amplification of the cylindrical mirror. According to the invention, one-dimensional integration is carried out on the optical signal through the cylindrical mirror, so that signal enhancement of the optical signal is realized, that is, pixel value improvement is carried out on a rotating image passing through the cylindrical mirror in the integration direction. Through the cooperation of the cylindrical mirror and the imaging detector, the reflected light of the object to be imaged is equivalently subjected to secondary integration, so that the pixels of the rotating image obtained by the imaging detector are easier to distinguish, and the finally obtained reconstructed two-dimensional image of the object to be imaged is clearer.

Description

technical field [0001] The invention relates to the imaging field, in particular to a unit detector optical tomography scanning time-division modulation imaging system. Background technique [0002] Object detection and tracking is a research topic of great interest to people all the time. In order to pursue a better target detection effect, the detection of target imaging technology has always attracted much attention. Existing imaging detection devices are mostly used in parallel light environments, and the resolution in natural light environments is far from ideal. Contents of the invention [0003] In order to solve the defect that the resolution of the imaging detection device in the prior art is not ideal in the natural light environment, the present invention proposes a unit detector optical tomography time division modulation imaging system. [0004] The object of the present invention adopts following technical scheme: [0005] A unit detector optical tomograph...
