WAERMEBILD-AUFNAHMEGERAET MIT EINEM MULTIELEMENT-DETEKTOR.

摘要

The imaging appts. has a multi-element detector (2) positioned at the centre of a concave autocollimation mirror (3) with a cooperating optical imaging system having an aperture opening for limiting the reception aperture of the multi-element detector (2). The latter is offset sidewards from the optical axis (1a) of the mirror (3), with a field lens mirror arranged symmetrically on the opposite side of the optical axis (1a), for ensuring that each single detector element (2a..2h) receives a single image. Pref. the multi-element detector (2) has a width of no more than 1 or 2 millimetres, with a similar degree of offset from the optical axis (1a).
