Abstract: A field multiplexed dispersive imaging spectrometer (20). The novel system includes foreoptics (22) for receiving incoming electromagnetic energy, a disperser (24) disposed to receive energy from the foreoptics (22), and a focal plane array (28) disposed to receive energy from the disperser (24). The disperser (24) is a computer generated holographic disperser designed to disperse light into several, overlapping diffraction orders. In the preferred embodiment, the disperser (24) is designed with greater energy in the central, undiffracted order than in the other diffracted orders. The system (20) also includes a processor (30) which takes the data detected by the focal plane array (28) and generates a representation of the input image in several color bands using an iterative restoration algorithm (32).
