We proposed an alternate configuration for dynamic multi-spectral imaging using a onesensor monochrome FireWire-A camera combined with a discretely tunable LCTF and developed an algorithm based on the traditional NDVI procedure to untraditionally solve the problem of image correspondence within sequences of spectral images collected from a moving platform. This algorithm had been shown to work well during acceleration, steady and deceleration phases of a moving platform under laboratory conditions.
