SPECTROGRAPHIC MULTI-BAND CAMERA

摘要

The present invention concerns a method and camera for obtaining a high- contrast image of a predetermined target present in an area under observatio n. The method involves obtaining an in-band image of the observation area including the target using a filter whose bands are aligned with selected characteristic wavelength bands of the target and an out-of-band image of th e observation area excluding the target using the filter with its bands non- aligned with the selected characteristic wavelength bands of the target. Processing of the in-band and out- of-band images results in a high-contrast image highlighting the presence of the target in the observation area and thereby allowing its detection and monitoring.
