Abstract: Disclosed is a combined lenses-based apparatus for line laser uniformity generation. The apparatus includes a laser diode, and an aspheric focusing lens and combined lenses that are arranged behind the laser diode sequentially. The combined lenses include a cylindrical lens and a plano-convex cylindrical lens. The cylindrical lens and the plano-convex cylindrical lens are arranged on an optical path sequentially. One end surface of the aspheric focusing lens is an aspheric surface. Light emitted by the laser diode is focused by passing though the aspheric focusing lens, and the combined lenses are able to disperse a focused beam into uniform line laser.

Abstract: A liquid crystal dimming film includes two substrates, two conductive layers, two free radical resisting layers and a liquid crystal layer. After the two conductive layers are electrically conducted, the electric field generated by the conductive layer can change the liquid crystal light transmission state of the liquid crystal layer. In addition, the free radical resisting layers are coated and photo-cured on both surfaces of the liquid crystal layer respectively. When the two liquid crystal layers are situated in a lighting environment, the free radical resisting layer can capture the free radicals produced by the liquid crystal layer to prevent the free radicals from affecting the conductive layer, thereby maintaining good photoelectric properties of the conductive layer.

Abstract: Disclosed herein is a laser shooting target based on photoelectric conversion, simulated shooting sound, and voice broadcast. A front panel is the main support structure and includes a target window, a speaker and a light-emitting diode (LED) display window. The covers may be injection molded of nylon or other plastic material. A homogenizing filter of conventional optical design is included to amplify a laser target area for a photoelectric conversion circuit to collect the light (laser) signal, and to filter out any influence of ambient or stray light on the photodetector. A target ring is printed on the target surface for reference for aiming at the time of shooting. The LED display adopts a digital display for showing the results of effective shooting of target rings. The LED display photoelectric conversion circuit are coupled to an MCU processor having processor readable instructions for operation.
