The multispectral imaging in surveillance systems is a powerful tool but the unavailability of cost effective equipment has prevented its use in many cases. We have developed a new hyperspectral imaging platform based on Piezo actuator tuneable Fabry-Perot Interferometers [1, 2, 3, 4] whose manufacturing cost is much less than cost of the existing systems. This platform can be used for example in the target specifi c spectral imaging which provides a means to identify the areas whose spectral characteristics are known a priori. The new system can perform a multispectral imaging at the target specific weighting of spectral transmissions [4] in a single exposure. This system could provide a new innovative low-cost hyperspectral camera for videosurveillance.
