  • Circuit arrangement for evaluating the output of a photodiode unit
    Patent number: 4914283
    Abstract: The intensity of the optical radiation varies within a wide range. The proportion of parasitic radiation registered by the photodiodes (D1 to Dn) increases with increasing radiation intensity. To exclude this parasitic radiation from evaluation, the photodiodes (D1 to Dn) are followed by analog comparators (K1 to Kn) with a variable reference voltage (Uref1). The reference voltage (Uref1) is varied by an analog comparator (Kz1) in porportion to the radiation intensity determined by a central photodiode (Dz).
