LASER RADIATION DETECTOR Russian patent published in 1995 - IPC

FIELD: measurement of energy of pulse optical radiation, laser radiation inclusive. SUBSTANCE: laser radiation detector uses the following components installed in succession in a mechanical contact: an absorber plate that is transparent to received radiation, intermediate member with a flange and an acoustic transducer with electrodes on its both surfaces; the intermediate member is made as a truncated cone, whose base exceeds the plate cross-sectional dimensions, and the upper section equals the section of the acoustic transducer; the thickness of the intermediate member is selected proceeding from relation (D-d)/h₂<0,4,; where D - cross-sectional dimension of intermediate member truncated cone; d - cross-sectional dimension of acoustic transducer section; h₂ - thickness of intermediate member. EFFECT: enhanced accuracy. 1 dwg
