Abstract

The invention relates to a continuous color matching device for a large color gamut and belongs to the technical field of optic precision measurement. The continuous color matching device comprises a first uniform area light source, a second uniform area light source, a fundamental color matching system, a complementary color matching system and a color mixer. The first uniform area light source comprises a first light source and a first small integrating sphere. The second uniform area light source comprises a second light source and a second small integrating sphere. The color mixer is formed by a large integrating sphere. The fundamental color matching system comprises a front flange A, a fundamental color filtering baseboard, three light barriers and a rear flange A. The complementary color matching system comprises a front flange B, a complementary color filtering baseboard, three light barriers and a rear flange B. The light barriers can make radial movements along light through openings. Different light barrier combinations can be selected, luminous flux of light in each color can be adjusted by moving the light barrier combination, tristimulus values of emitted light of the color mixer is changed by adjusting luminous flux ratio of the lights in six colors, so that color gamut of the emitted light can be controlled, and larger light output power can be realized.

Description

technical field [0001] The invention relates to a continuous toning device with a large color gamut and belongs to the technical field of optical precision measurement. technical background [0002] In recent years, with the development of science and technology, the application of color in various fields has become more and more extensive. In the fields of robot vision, color vision inspection of special personnel, photoelectric tracking and aiming fire control, textile, architecture, environment and art, the importance of color is particularly prominent. Therefore, the measurement of color has become a basic problem in these fields. In order to accurately detect the color of an object or evaluate the color resolution ability of an object, a light source with a large color gamut, high power, and stable performance is required. [0003] Generally, a color card and a prism can be used to generate a light source of a specific color, but both methods have defects. Placing a s...
