A spectrally-filtered, miniature, imaging spectrometer system for airborne remote sensing data acquisition with a two dimensional field of view. Synchronized CCD-imager sensor modules or cameras are aligned to a common field of view. One sensor module has a visible range variable interference filter on its surface and a second module has a near-infrared range variable interference filter on its surface. Video data from the three sensor modules is combined and recorded on a single analog or digital recorder. Futher, such video data is monitored by a computer and used to control the shutter speed of each of the three sensor modules. Wavelength spectral image data and directional spectral image data are acquired by a single pass over a target area. Post-processing of such data produces reconstructed track-recovery-images extracted from a sequence of video frames for the spectral regions of interest at a fixed column position to produce multiple bands of monochrome images.
