Abstract

The invention relates to a realization method of a programmable light source system based on a DMD, wherein an ultra wideband output of 400 nm-2400 nm is output by a super-continuous light source at first, and output light is collected by a paraboloid mirror to form parallel light; and the parallel light is split though a dispersing prism combination, the dispersed light is focused by a columnar convex lens, and the light with different wavelengths is projected to the DMD. A DMD control program selects the wavelength by selecting reversal of prisms on different rows. A to-be-output waveband is reflected by a micro mirror to one direction; and unselected wavebands are reflected to other directions. The to-be-collected light reflected by the DMD micro mirror passes through an inverted dispersing prism to offset original dispersing in order to reintegrate the reflected light into the parallel light, and then the parallel light is collected by the paraboloid mirror to an input end of a collection optical fiber. Finally, the whole system realizes rapid programmable outputting by controlling the reversal of the micro mirror on the DMD.

Description

technical field [0001] The invention relates to the field of optical engineering, in particular to a method for realizing a DMD-based programmable light source system. Background technique [0002] Broadband light sources include traditional mercury lamps, xenon lamps, deuterium lamps, QTH lamps, and SLEDs (SuperLuminescent LEDs). Relatively new technologies include laser-pumped broadband light sources developed by Energetiq Corporation of the United States. These light sources emit light based on black body radiation or arc plasma discharge, which are incoherent light sources. It has the characteristics of large luminous area, not easy to collect and focus. To obtain a single wavelength output, a monochromator system is usually required. However, due to the large light-emitting area, the energy of this light source attenuates sharply after passing through the monochromator. [0003] With the development of ultrafast lasers, the Supercontinuum light source (Supercontinuu...
