Abstract

The invention provides an optical darkroom optical performance detection method and an optical darkroom optical performance detection system. The method comprises the steps of identifying the walls ofan optical darkroom in space geometry, defining each wall as a single detection area, setting detection points in each detection area, testing the reflectivity of each detection point, acquiring thereflectivity detection result of each detection point, and building an evaluation model to characterize the optical performance detection result of the optical darkroom. Throughout the process, detection areas are set in a reasonable way for the geometric walls of a dark room, a certain number of detection points are set in each detection area, and finally, an evaluation model is used to characterize the optical performance detection result of the optical darkroom.

Description

technical field [0001] The invention relates to the technical field of optical detection, in particular to a detection method and system for optical performance in an optical darkroom. Background technique [0002] The optical darkroom is mainly widely used in optical tests that require weak light intensity, such as the distribution photometer environment, the verification room of optical instruments such as illuminance meters and luminance meters, and the photobiological safety test system laboratory. [0003] At present, in the field of optical measurement technology, such as JJG 245-2005 "Verification Regulations for Illuminance Meters", JJG 211-2005 "Verification Regulations for Luminance Meters", JJG 212-2003 "Verification Regulations for Color Temperature Meters", etc., only mark the test environment as Darkroom, it does not quantify the darkroom evaluation and judgment criteria. [0004] There are many darkroom applications, but there is no unified quantitative evalu...
