An optoelectronic circuit for autocorrection of photodetector information signals by a reference light meander signal automatically corrects the time of storing output pulses of a voltage-to-frequency converter included in the circuit of encoding information signals. In a single-beam spectrophotometer with an FEU-100 photomultiplier, the signal-to-noise ratio at low frequencies (from 0.001 to 0.02 Hz) is 10-15 times higher. The device requires no mechanical chopper of light flux due to the use of a stabilized light-meander source.
