Description

Class  G01J : MEASUREMENT OF INTENSITY, VELOCITY, SPECTRAL CONTENT, POLARISATION, PHASE OR PULSE CHARACTERISTICS OF INFRA-RED, VISIBLE OR ULTRA-VIOLET LIGHT; COLORIMETRY; RADIATION PYROMETRY


Subclass 1/34: Photometry, e.g. photographic exposure meter (spectrophotometry G01J 3/00; specially adapted for radiation pyrometry G01J 5/00) by comparison with reference light or electric value intensity of the measured or reference value being varied to equalise their effects at the detector, e.g. by varying incidence angle using separate light-paths used alternately or sequentially, e.g. flicker
