Acousto-optic modulation type wide-spectrum multichannel polarized monochromatic light source

The utility model discloses an acousto-optic modulation type wide-spectrum multichannel polarized monochromatic light source. According to the device, a parabolic reflecting cover, confocal off-axis parabolic reflecting mirrors and a diaphragm are utilized, and therefore, light energy utilization efficiency can be improved, and stray light interference can be decreased; a visible spectrum, a short-wave spectrum and a medium-wave infrared spectrum which are formed through beam splitting of a color separation film are modulated through an acousto-optic tunable filter, so that a wide-spectrum, multichannel and tunable polarized monochromatic light source can be obtained. No moving parts exist in the light source. The acousto-optic modulation type wide-spectrum multichannel polarized monochromatic light source has the advantages of stable spectral characteristics, high linear polarization characteristics, miniaturization, low power consumption, light weight and so on, and can well satisfy requirements of field environments.
