Abstract

The light filed modulated imaging spectrometer (LFMIS) can obtain a multispectral data cube in a single shot. The spatial sampling is effected by the design of spectral filters, because the diffraction limit increases as the sizes of the filters decrease. The spatial and spectral sampling characters of the system are determined by the system parameters, specially the parameters of the filters. This research presents the models of the system and the linear-variable optical filters (LVFs). The spatial sampling character is analyzed theoretically and confirmed by simulation results. Simulation experiments are performed to analyzed the characters of LVFs that effect the spectral sampling character. The results provide the parameter requirements of LVFs when designing an LFMIS system based on LVFs.
