Method for measuring luminescence distribution

Abstract

A method for measuring a luminous distribution is as follows: the spatial luminous distribution of a light source is measured through a curved mesh screen and an imaging measurement unit which comprises an area array sensor, specifically comprising: the curved mesh screen has a sampling port, and the surface of the curved mesh screen has diffuse transmission elements distributed in a grid pattern; a to-be-measured region of the light source is placed at the sampling port, light emitted from the to-be-measured region irradiates the curved mesh screen to form a light spot on each diffuse transmission element, and each light spot region corresponds to a spatial angle; the imaging measurement unit obtains a light image formed by the diffuse transmission elements on the curved mesh screen; and a data processing unit analyzes the light image to obtain angular resolved optical quantities of the to-be-measured region.
