FACILITY FOR DETECTION AND CONVERSION OF POWER OF RADIATION SOURCE ( VERSIONS ) Russian patent published in 2002 - IPC

FIELD: detection and conversion of radiation power. SUBSTANCE: there are proposed two versions of facility for detection and conversion of power of radiation source in which amplitude modulation with shift of signal spectrum from low-frequency region to relatively high-frequency region is realized. According to first version facility includes radiation source, first radiation detector and self-excited oscillator, frequency divider, single-shot multivibrator, circuit controlling electric motor and electric motor with modulator connected in series, additional radiation source connected to output of self-excited oscillator and second radiation detector optically coupled to it and connected in series with input of first radiation detector which output is connected in parallel to inverting input of operational amplifier with resistor in feedback circuit. In agreement with second version amplitude modulation is realized by electronic procedure which excludes mechanical modulator, electric motor rotating it and its control circuit. Radiation source is connected directly to output of single-shot multivibrator. EFFECT: improved signal-to-noise ratio while receiving signals in wide spectrum range, enhanced reliability, simplified design and provision for safe operation of facility. 2 cl, 2 dwg
