ACOUSOOPTICAL RECEIVER-FREQUENCY METER |
摘要 |
FIELD: radio measurement instrumentation. SUBSTANCE: invention refers to high-sensitivity receiver-frequency meter employed in communication, direction finding and radio reconnaissance systems. Heterodyne method of reception is used in receiver-frequency meter to raise its sensitivity and its circuit incorporates source of laser radiation with amplitude modulator and first source of modulating voltage, collimator and acoustic deflector with integrating lens, second source of modulating voltage loaded to position-sensitive photodetector with set of amplifiers of difference frequency. EFFECT: raised sensitivity of meter. 1 dwg
