Abstract

An elaborate Hadamard transform infrared imaging spectrometer system based on the digital mirror device (DMD) is proposed in this paper, through which the implementation of Hadamard coding in this system is revealed. Derivation of the process of spectra radiation transmission covers the influence factors of target radiative characteristics, atmospheric environment, optical system, dispersion, DMD modulation, spectrum response of detector, Hadamard encoding and decoding etc. A simple physical scene is introduced including diverse materials and model tank and simulation results are given by the transfer model with real-time meteorological data, real-time temperature data and imaging system parameters.
