Optical fiber scanning projection equipment

Abstract

The invention discloses optical fiber scanning projection equipment which comprises a light source driving device, a light source, a light splitting device, a light source chromaticity detection device, a light combining device, an optical fiber coupling device and a scanning optical fiber. The light source driving device is connected with the light source, the light splitting device is arranged at an emergence end of the light source, the light source chromaticity detection device is arranged at a first emergence end of the light splitting device and is connected with the light source drivingdevice, the light combining device is arranged at a second emergence end of the light splitting device, the optical fiber coupling device is arranged at the second emergence end of the light splitting device, and the scanning optical fiber is arranged at an emergence end of the light combining device; light rays emergent from the light source can be adjusted by the light source driving device according to detection results of the light source chromaticity detection device. The optical fiber scanning projection equipment has the advantages that colors of the light rays emergent from the lightsource can be adjusted by the optical fiber scanning projection equipment according to the detection results, the correctness of the white balance of the emergent light rays can be guaranteed, and accordingly the chromaticity of the light rays emergent from the optical fiber scanning projection equipment can be calibrated according to actual operation conditions of the optical fiber scanning projection equipment.

Description

technical field [0001] The invention relates to the field of optical fiber scanning, in particular to an optical fiber scanning projection device. Background technique [0002] Projection equipment is a common equipment in people's daily life, and has been used more and more in conferences, home entertainment, etc. [0003] The color of the projected image is an important parameter of the projection device, which will greatly affect the visual experience of people watching the projected image of the projection device. The color is determined by the brightness and chromaticity. It is the property of the color not including brightness, it reflects the hue and saturation of the color, for the light composed of three monochromatic lights of red (R), green (G) and blue (B) Generally speaking, the chromaticity of the light depends on the proportion of each monochromatic light. Therefore, in the prior art, the projection equipment is generally adjusted according to the temperature...

[0003] The color of the projected image is an important parameter of the projection device, which will greatly affect the visual experience of people watching the projected image of the projection device. The color is determined by the brightness and chromaticity. It is the property of the color not including brightness, it reflects the hue and saturation of the color, for the light composed of three monochromatic lights of red (R), green (G) and blue (B) Generally speaking, the chromaticity of the light depends on the proportion of each monochromatic light. Therefore, in the prior art, the projection equipment is generally adjusted according to the temperature and other parameters during use when the projection equipment leaves the factory, so that the projection equipment can emit The light of the correct color, however, the actual situation of the projection device during use may be different from the parameters used for adjustment. For example, the temperature of the projection device during use will have differences in heat dissipation due to different ambient temperatures , making the color temperature of the light source inconsistent with the color temperature during adjustment, which will cause people to be unable to obtain a satisfactory color experience
