Abstract

The invention discloses a slit-free image streak tube with multiple electric deflection fields and an imaging processing method thereof, relates to a streak tube and aims to solve the problem that time and space overlap is easily introduced into the conventional streak tube, so that imaging cannot be performed in the absence of an optical fiber converter and a slit. Two pairs of electric deflection pressing plates are arranged inside the conventional streak tube; three pairs of deflection voltage plates form six side faces of a hexagonal prism; each pair of deflection voltage plates are arranged in parallel; one deflection voltage plate in each pair of deflection voltage plates is connected with a driving voltage signal; and the other deflection voltage plate is connected with the power ground. A blank image to be restored with the same size as that of a streak image acquired by the streak tube is established, the blank image to be restored comprises multiple points to be restored, and each point to be restored is traversed, the strength values in the image are searched at the same speed in three streak images along respective deflection directions by taking the point to be restored as an original point, and when the same strength value is obtained at three searching points, the strength value and distance value of the points to be restored are determined. The slit-free image streak tube is used for streak tube imaging.

Description

technical field [0001] The invention relates to a stripe tube, in particular to a slitless imaging stripe tube with multiple deflection electric fields and an imaging processing method thereof. Background technique [0002] The imaging lidar with a single slit stripe tube as a detector, this imaging mechanism determines that the laser as the emission source and the stripe tube as the detector need to work at a very high frequency at the same time. Since the number of different laser stripe spots required to scan all targets in the field of view is different, this frequency may be ten times, dozens of times or even hundreds of times the imaging frequency. In the case of ensuring that the single pulse energy of the laser does not decrease, the laser emission frequency cannot be greatly increased, which restricts the final imaging frequency of the entire radar system. [0003] In order to solve the difficulty of imaging frequency, multi-slit stripe tube lidar was designed and ...
