Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] like figure 1 , 2 As shown, a color-segmented three-dimensional projection device based on band-pass color wheel filtering includes a left projector 1 and a right projector 2 corresponding to the left eye and the right eye respectively, and the left projector 1 and the right projector 2 each includes a light source 3, a band-pass color wheel 4 capable of performing RGB three-channel filtering, a digital micromirror device DMD5, and a projection lens 6, and the light source 3, the band-pass color wheel 4, and the digital micromirror device DMD5 are arranged in sequence, The projection lens 6 is located on the reflection path of the digital micromirror device DMD5.
[0022] The bandpass color wheel 4 includes a color wheel body that can rotate around the center, and an R color bandpass filter 40, a G color bandpass filter 41 and a B color bandpass filter are inl...
