Bilddetektor mit vermindertem Störlicht und Anwendung auf einen Endsensor

摘要

The detector includes a surface (7) which is sensitive to photon and reflective radiation and in front of which, integral with a housing (2), is placed a transparent window (11) including an internal dioptre lens (12) and an external dioptre lens (13). According to the invention, the transparent medium of the window is non-diffusing and attenuates photon radiation, the internal dioptre lens (12) is at a distance from the sensitive surface (7) which is of the order of the detector's resolving distance, and the external dioptre lens (13) is far enough from the sensitive surface to obtain a large spread in the parasitic halation due to this external dioptre lens. …Application to an earth sensor for visible radiation. ……
