GONIOPHOTOMETRIC INSTALLATION FOR MEASUREMENT OF PARAMETERS OF LIGHTING PRODUCTS AND CHARACTERISTICS OF RADIATION SOURCES Russian patent published in 2023 - IPC G01J1/42 

FIELD: metrology of parameters of radiation sources.

SUBSTANCE: claimed device for measuring radiation parameters contains a goniometer located on one axis with the possibility of changing the distance relative to each other (photometric distance), made with the possibility of installing a tested radiation source on its rotating platform, and at least one radiation sensor with an input window, with the possibility of changing the area of such a window. Moreover, the goniometer is configured to rotate the tested radiation source relative to the said axis in at least two planes of space, with the possibility of fixing the corresponding rotation angles with non-incremental sensors, and the radiation sensor is configured to transmit measurement results for each increment of the rotation angle in digital or analogue form, at the same time, its input window is made with the possibility of changing its dimensions on the condition that the angular size of such a window at the distance of photometry corresponds to the given illumination conditions and the minimum increment of the goniometer rotation angle.

EFFECT: increased accuracy, speed and dynamic range of measurements of luminous intensity (radiation intensity) and its spatial distribution.
