FIELD: optical measurement techniques. ^ SUBSTANCE: laser radiation receiver has diaphragm mounted in series to have mechanical contact with incident radiation dissipater, which members are fixed to have air gap in front of entrance window, radiation absorber and acoustic transducer piezoelectric element). There are electrodes at both surfaces of piezoelectric element. Liquid is used as absorber, which liquid absorbs incident radiation volumetrically. Receiver can be additionally provided with registrar connected to acoustic transducer (piezoelectric element) through capacitive voltage divider. Registrar is started by means of synchronizing photoreceiver. ^ EFFECT: widened range of measured energies. ^ 5 cl, 1 dwg |
