Star simulator target standard source based on micron-sized LED light emitting technology

The invention provides a star simulator target standard source based on a micron-sized LED light emitting technology, and belongs to the technical field of optical measuring instruments. The star simulator target standard source comprises a box body, a lens cone, a crossed reticle, an attenuation slice, an optical filter, a LED light source, an electrically-controlled mobile station for positioning the LED light source, a thermostat and a subtle controllable power source, wherein the lens cone is mounted on the side end surface of the box body; the crossed reticle, the attenuation slice and the optical filter are successively mounted in the lens cone; the electrically-controlled mobile station for positioning the LED light source, and the subtle controllable power source are mounted on the inner bottom surface of the box body; the LED light source is mounted on the electrically-controlled mobile station for positioning the LED light source; the thermostat is mounted on the back of the LED light source. The star simulator target standard source provided by the invention is simple in the whole construction structure and is convenient to mount; through the adoption of the star simulator target standard source, the simulation of first-magnitude stars to fifth-magnitude stars can be realized, the spacing precision of stars is smaller than or equal to 1+/_ 1 m, the star points can be controlled in real time, and the deployment and the maintenance of the device are convenient and rapid.
