The performance of a modified Rj-7000 (MRj) radiometer in measuring low-level 1064-nm radiation is evaluated experimentally using the P-3 pulsed-laser radiometer at NBS. The MRj comprises an antireflection-coated 1-sq-cm Si PIN photodiode, a microprocessor-based receiver, a filter and aperture wheel, and 200-mm-focal-length telescopic optics focusable from 3 m to infinity. The P-3 radiometer employs a beam splitter and a 100-mm collector lens to permit simultaneous measurement with a PIN photodiode (basically identical to that of the MRj) and with an avalanche photodiode. Tests were performed using a collimated beam of half-power pulse width 15-20 ns from an LED. The results are presented graphically, and the addition of the telescope optics in the MRj is shown to increase the gain by about three orders of magnitude; the minimum detectable optical signal is found to be about 6.0 fJ/sq cm, with rms noise floor + or - 1.0 fJ/sq cm.
