Embodiment Construction
[0018] Please refer to FIG. 2 , which is a schematic structural diagram of the first embodiment of the fiber optic projector of the present invention. The fiber optic projector includes a light source 21, an optical fiber bundle 23, a brightness modulation system 25, and a projection lens group 27, wherein the optical fiber bundle 23 includes a plurality of optical fibers 232, and one end of the plurality of optical fibers 232 forms a light incident One end is used to receive the light emitted by the light source 21, and the other end constitutes an emitting end. The light brightness modulation system 25 is arranged between the light incident end and the light output end, and is used to control the bending degree of the optical fiber 232 in the optical fiber bundle 27, so as to realize brightness modulation. The projection lens group 27 includes at least one projection lens 272 capable of projecting the light signal modulated by the brightness modulation system 25 onto the scr...
