Some key aspects of microoptic imaging systems will be explored, with an emphasis on imaging spectrometers. As a design example, a space-variant variable-dispersion imaging micro spectrometer is described. An array of MEMS mirrors is used to select different optical paths through the spectrometer, permitting dynamically adjustable grating dispersion on a pixel-by-pixel basis across the image. Design trade-offs and performance limitations are addressed.
