Abstract :
We describe a novel method to measure the relative spectral responsivity of detectors based on a pulsed OPO tunable from 210 nm to 2000 nm. Si and InGaAs photodiodes are compared to a pyro-electric detector as Reference (REF) at each laser pulse from the OPO with a duration of several ns and a repetition rate of 1 kHz based on a beam splitter and single-pulse data acquisition.
