Optical measuring device of double rotating shafts and measuring method thereof

Abstract

The invention discloses an optical measuring device of double rotating shafts and a measuring method thereof. The optical measuring device comprises a base, a first rotating motor is connected with a first worm and gear speed reducer, the first worm and gear speed reducer is connected with a light source rotating plate, and a light source is arranged at the end of the light source rotating plate; the second rotating motor is connected with a second worm and gear speed reducer, the second worm and gear speed reducer is connected with an optical fiber head rotating plate, and an optical fiber head is arranged at the end part of the optical fiber head rotating plate; a semi-integrating sphere lifting column is fixed on the base, a semi-integrating sphere cantilever is connected with the semi-integrating sphere lifting column, and the semi-integrating sphere cantilever is connected with the semi-integrating sphere; the first worm and gear speed reducer and the second worm and gear speed reducer are coaxially installed, and the light source rotating plate and the optical fiber head rotating plate are arranged in a staggered mode. According to the invention, the double rotating shafts are driven by the rotating motor and the worm and gear, and the two rotating shafts keep rotating coaxially, are arranged in a staggered manner in the vertical direction, do not interfere with each other, and can flexibly rotate by 0-180 degrees, so that optical measurement at different angles is realized.

Description

technical field [0001] The invention relates to the technical field of optical measurement, in particular to an optical measurement device with dual rotation axes and a measurement method thereof. Background technique [0002] Optical measurement equipment is used in the LCD industry to measure optical parameters such as chromaticity and brightness of the light-emitting surface of the LCD panel. With the beginning of the high-definition TV era, in order to better restore sharp, bright and high-resolution images, the development of some higher-quality display devices supporting full high-definition is also accelerating, and the various conditions for detection are also increasing. [0003] At present, the optical measuring machine with various instruments in the industry can only be used for optical measurement of different heights and different background environments. For optical measurement under the irradiation of reflected light, the reflected light instrument emits ligh...
