doi:10.16182/j.issn1004731x.joss.17-0078

Abstract

Abstract: The streak tube laser three-dimensional imaging system is one of the most promising practical laser imaging systems, because of its high precision, large field of view and high frame frequency. A multispectral imaging simulation algorithm for multi-slit streak tube is proposed based on the research of the multi-spectral imaging. The derivation of the main structural parameters is given. The influence of the number of different detectors on the time resolution and spatial resolution of the system is analyzed. In the model of the simulation system, the laser echo signals of multiple wavelength bands are fed into the photocathode of the same streak tube at the same time by the fiber array. The simulation experiments are carried out for the cases of 64×64 and 128×128 pixels. The experimental results verify the feasibility of the algorithm.
