Recording of Low-Power Nanosecond Radiation Pulses by a Detector Based on a Thin-Film Pyroelectric Structure

Results of an experimental study of a thin-film pyroelectric detector of radiation based on strontium barium niobate and used for detecting nanosecond radiation pulses are reported. The possibility of recording 30-ns radiation pulses with the sensitivity of 1 V/W (NEP = 8 · 10−7 W/Hz1/2) is demonstrated.
