Snapshot spectral imaging with depth estimation based on mapped light field and coded light field

In recent years, the snapshot multi - dimensional imaging technology is emerging and becomes an increasing research focus. Especially, the spatial, spectral and depth information of scenes is particularly useful in target detection, recognition, tracking, scene classification et al. This paper proposes a snapshot compressed light field imaging spectrometer based on compressed sensing with light field concept and a snapshot depth - spectral imaging architecture based on image mapping and light field to realize the capture of depth - spectral information simultaneously. Through simulations, we demonstrate that the proposed snapshot depth - spectral imaging systems are effective to measure the depth - spectral information of scenes in a single snapshot time.
