Object scene detecting device for use in guided missile, has separation lens comprising prism coupled with optical fibers that are optically connected with emitter unit and detector unit, respectively

摘要

The device (1) has an imaging optical sensor system with a separation lens (4) arranged in a central recess (3) of an incident lens (2). An emitter unit (5) is provided for radiation emission. The separation lens has a prism coupled with optical fibers (19a, 19b) that are optically connected with the emitter unit and a detector unit (6), which is activated by target radiation of the emitter unit, respectively. The incident lens is designed as a cassegrain lens, which comprises a concave parabolic primary mirror (10) and a convex hyperbolic secondary mirror (11).
