- G - Physics
- G01J - Measurement of intensity, velocity, spectral content, polarisation, phase or pulse characteristics of infrared, visible or ultraviolet light; colorimetry; radiation pyrometry
- G01J 1/36 - Photometry, e.g. photographic exposure meter 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 using electric radiation detectors
