光场成像光谱仪成像模型及仿真

light field imaging spectrometry can capture 2D spatial and 1D spectral information of light rays from a scene in one capture and re-distributes the 3D information on a 2D detector array. In this paper, a snapshot light field imaging spectrometer based on a microlens-array and a filter-array is analyzed. The transmission of target spectral information trought the system is established. The correlation model etween the sensor pixels and spectrum information is also provided. A light-field spectral image is synthesized based on the correlation model. Furthermore, the spectrum information is reconstructed by using the correlation model.
