Abstract

The invention provides a device for producing a uniform area light source with continuously adjustable colors, and belongs to the technical field of optical precision measurement. Light emitted from the uniform area light source is incident to a continuous color mixing system; the incident light is divided into three beams of three-primary-color light by a base plate of a color filter; a red light barrier, a green light barrier and a blue light barrier respectively shield corresponding color light; tristimulus values of the emergent light of the continuous color mixing system are changed by changing the ratio of optical areas of the three beams of light and adjusting the ratio of luminous fluxes of the three color light; and after the three color light is mixed through the continuous color mixing system, the uniform area light source with specific color is output at a light outlet of a IIth integrating sphere. The invention provides the continuous color mixing system capable of independently adjusting the three color light so as to realize accurate color adjustment of emergent light. The device has the advantages of continuous color adjustment and high output power, and can be used for measuring the resolution of colors.

Description

technical field [0001] The invention relates to a device for producing a uniform surface light source with adjustable color, which belongs to the technical field of optical precision measurement, and is especially suitable for producing a uniform surface light source with continuously adjustable color. 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 high power, stable performance and the ability to produce various colors is require...
