A positioning system and photometer as a whole are termed
‘goniophotometer’, which is defined as a specialized instrument for
measuring the angular variation of a given photometric level. This paper
explains the design and calibration of a new automated goniophotometer
based on double reflection in order to reduce the size of the system. This
goniophotometer is suitable for measuring several photometric magnitudes
(luminance, luminous intensity. . . ) with no need for auxiliary detectors.
