Abstract

Sampling and attenuation of the laser beam to be measured is the first step for detector array target to measure temporal and spatial distribution of laser intensity. Existing sampling attenuation technology is more sensitive to the incident angle of laser beam. In practical applications, sampling angle response characteristics of laser beam can be measured experimentally, and get the coefficient to be corrected. Among them, scattering sampling method is based on scattering parameters of selected sampling material, which can effectively correct sampling angle response in theoretical or simulation stage. In this paper, focusing on angular characteristics of scattering sampling for detector array target, based on bidirectional transmission distribution function, the correlation between the scattering sampling angular characteristics and scattering distribution is derived. Experiments have proved that scattering sampling angle characteristic for detector array target can be expressed in the form of ratio of material scattering distribution function. This characteristic provides a certain guidance for design of scattering sampling angle tolerance for detector array target.
