Abstract

The invention relates to a full-vector information target polarized image time-sharing delivery simulation device and method and belongs to the target simulation technical field. According to the simulating device of the invention, a computer is connected with a DMD 1 through a frequency dividing circuit; the computer is also connected with a controller; and the controller is connected with a polaroid polarizer and a liquid crystal polarizer; and a micromirror array in the DMD 1, the polaroid polarizer, the liquid crystal polarizer and an acquisition camera are arranged sequentially in an optical-coaxially manner. According to the simulation method of the invention, the computer transmits target image electrical signals to the DMD 1, and the frequency dividing circuit carries out six-frequency division processing on the target image electrical signals; the DMD 1 converts the target image electrical signals which have been subjected to the six-frequency division processing into six target image optical signals; under the control of the computer and the controller, after the six target image optical signals pass through the polaroid polarizer and the liquid crystal polarizer according to a time sequence, 0-degree, 45-degree, 90-degree and 135-degree linearly polarized vector information as well as left-handed and right-handed circularly polarized vector information are obtained; and the acquisition camera acquires a target polarized image containing full-vector information.

Description

technical field [0001] The invention relates to a time-sharing delivery simulation device and method of full-vector information target polarization images, belonging to the technical field of target simulation. Background technique [0002] Based on the principle of Stokes vector polarization imaging, light is regarded as a Stokes vector. The Stokes vector is a 4×1 matrix S=[IQUV], where the component I represents the total light intensity, and the components Q and U describe the linear polarization components, where Q describes the horizontal and vertical ie 0° and 90 °linear polarization component, U describes the 45° and 135° linear polarization, and component V represents the circular polarization component. The change of the polarization state of the incident light by the polarization optical system can be described by the 4×4 Mueller matrix M: [0003] [0004] The polarization state S of the incident light for polarized imaging 0 =[I 0 Q 0 u 0 V 0 ] T , aft...
