Latest Patents
Cojan's latest patents include a method and system for protecting optoelectronic search and tracking equipment from illumination. This innovative system allows for homing on a useful target even in the presence of considerable parasite sources, such as sunlight, in the field of observation. The system features elements for spatial and spectral discrimination of infrared light sources, which are formed with a detector strip preceded by a fixed modulation grid. It also includes a uniaxial field scanning device, switchable electronic filtering, and both band pass and low pass filters. The grid is preferably designed with herringbone patterned tracks. The narrow band filter is centered around 4.4 microns, while the wide band filter covers 3 to 5 microns, facilitating missile homing through optical deviation heading measurement in ground/air or sea/air defense systems.
