A temporally and spatially non scanning imaging spectrometercomputed tomography imaging spectrometer (CTIS) is introduced. The primary theories are described in details and a mathematical model is built. The system projector matrix of the model is calculated. With the SVD reconstruction algorithm, the simulated experiments are performed. The results show that the reconstruction algorithm is efficient and precise, and that the model and the theorem are all right.
