PCT No. PCT/SE85/00133 Sec. 371 Date Nov. 8, 1985 Sec. 102(e) Date Nov. 8, 1985 PCT Filed Mar. 26, 1985 PCT Pub. No. WO85/04773 PCT Pub. Date Oct. 24, 1985.An apparatus for increasing the dynamic range of an integrating input stage in an optoelectric receiver by means of a feed-back (F2) between the output of an amplifier (F1), associated with the stage, and the pole of an optoelectric converter (D) facing away from the input of the amplifier (F1). The gain of the feed-back can be controlled in response to the luminance with the aid of a transducer (G) connected in series with the converter (D). |
