Embodiment Construction
[0016] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0017] combined with figure 1 It can be seen that the device includes a light source, lens group, DMD, lens, mirror and imaging position panel; ultraviolet light is emitted from the light source, converted by the lens group, and projected onto the DMD with better collimation. Tens of thousands of micromirrors, according to the picture information on it, selectively project light energy into the lens, the lens forms an image of the light beam carrying the picture information, and places the image surface on the imaging panel through the mirror; in order to improve the resolution of the projected picture When the picture information is input to the DMD, half of the picture information just covers all the micromirrors ...
