Embodiment Construction
[0011] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0012] In the embodiment of the present invention, an array of LED point light sources of different colors is used as the light source of the grating stripe projection system, and the light source array can complete strobe within the order of us, and a pair of inverted prisms or a For reflective gratings placed in parallel, since the triangular prism or reflective grating has a dispersion effect on light of different colors, when light sources of different colors are used for projection illumination, the projection image of the grating will translate along the direction of dispersion, thus obtaining...
