Abstract

The invention relates to a structure for reducing speckles and improving light spot uniformity and a laser searchlighting device. The structure comprises a laser generator and an optical fiber, the structure is characterized by further comprising a vibration motor, the output position of the vibration motor is fixedly provided with m polarization correcting plates, the m polarization correcting plates abut against the side wall of the optical fiber at the same time, and the n polarization correcting plates and the m-n polarization correcting plates are respectively arranged at two sides of theoptical fiber. The structure has the effect of reducing the speckles.

Description

technical field [0001] The present application relates to the field of imaging, in particular to a structure for reducing speckles and improving the uniformity of light spots, and laser search equipment. Background technique [0002] In night lighting imaging, it is necessary to irradiate the object or area to be imaged with a light source, and then acquire an image of the area through an image acquisition device. In order to reduce light pollution, related technical means usually use laser light in the wavelength band invisible to human eyes as the light source. [0003] In view of the above-mentioned related technologies, the inventors found that during the imaging process at night, the laser light generated by the laser generator is still irregular when it is reflected and emitted in the optical fiber many times, causing the imaging effect in the image acquisition device to appear as There are many light spots and speckles, and the uniformity is poor, and the edge of the...
