Coaxial self-aiming spectral measurement system and measurement method

Abstract

The invention relates to a coaxial self-aiming spectral measurement system and method, and the system comprises a rotating wheel, and one side of the rotating wheel is provided with an imaging system; at least one of the optical filter and the light source is mounted on the rotating wheel; the optical fiber is arranged on the other side of the rotating wheel, the end, away from the rotating wheel, of the optical fiber is connected with an imaging lens, the optical fiber, the optical filter and the imaging system are coaxially arranged, or the optical fiber, the light source and the imaging system are coaxially arranged. Due to the fact that the light source is arranged on the rotating wheel, light emitted by the light source can be irradiated on a spectral measurement area on the display screen through the optical fiber and the imaging lens to aim at a light path, and after the light source is turned off, emergent light of the optical fiber is imaged to the imaging system through the optical filter to achieve spectral measurement. High-precision aiming of spectral measurement can be realized; and the ND optical filter can reduce the light intensity, so that the measured brightness range is wider.

Description

technical field [0001] The invention relates to the technical field of spectrum measurement, in particular to a coaxial self-aiming spectrum measurement system and a measurement method. Background technique [0002] With the rapid development of display technology, people have higher and higher requirements for display quality and performance of display devices. Displays such as LCD, OLED, MiniLED, and MicroLED are becoming more and more widely used. Display technologies featuring high brightness, wide color gamut, high efficiency, and long life have been rapidly developed. [0003] The spectrometer is a basic optical measurement instrument. Its principle is to obtain the spectral power distribution curve of the incident light by collecting the radiated, reflected or transmitted light signals of the target object, and then to analyze the incident light. Various details, such as radiometric, photometric and colorimetric physical quantities, enable the identification of the ...
