Problems solved by technology

[0005] figure 1 , figure 2 or image 3 As shown in the system for realizing beam homogenization, this method requires multiple lenses or two high-order aspheric aspheric lenses. The debugging process of such a large number of optical devices is very complicated, and it is easy to cause errors. At the same time, the manufacturing cost and difficulty of such an optical system are very high, and it is not easy to achieve large-scale use

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] See Figure 4 , Figure 4 It is a schematic flowchart of a method for realizing beam homogenization according to an embodiment of the present invention. The optical device in the embodiment of the present invention is a double aspherical lens, and the non-uniform light beam adopted is a Gaussian light beam. Since other non-uniform light beams that can be expressed by formulas are only different from the Gaussian light beam in light distribution, the principle is the same. So no more details. Such as figure 2 As shown, the method includes:

[0022] Step S101, the first aspheric surface of the optical device receives the input laser Gaussian beam and then diverges or focuses the beam. The two aspheric surfaces of a double aspheric len...

Abstract

The embodiment of the invention discloses a method for realizing light beam homogenization. The method comprises the following steps that: a first aspherical surface of an optical device receives input nonhomogeneous light beams, and diverges or focuses the light beams; a second aspherical surface of the optical device outputs flat-top beams collimated to be in uniform distribution by changing the phase of the beams diverged or focused by the first aspherical surface; the bending direction of the second aspherical surface is consistent with that of the first aspherical surface. The embodiment of the invention also discloses an optical device. The method can accomplish the homogenization of nonhomogeneous light beams by adopting the least optical devices, which avoids the complex debugging for a plurality of the optical devices and saves use cost as well as manufacturing cost at the same time.

Description

technical field [0001] The invention relates to the field of optics, in particular to a method for realizing beam uniformity and an optical device. Background technique [0002] With the increasing application of semiconductor lasers such as LD (Laser Diode, laser diode), LED (Light Emitting Diode, light-emitting secondary light), VCSEL (Vertical Cavity Surface Emitting Laser, vertical cavity surface emitting semiconductor laser), solid-state lasers and gas lasers , the homogenization of inhomogeneous beams, especially Gaussian beams, has become a very necessary problem in many application fields. Such as laser irradiation, ranging, free space optical communication, laser pumping, holography, coherent optical data processing, high resolution dynamic infrared radar system, laser drilling, laser marking, laser welding, laser photocopying and optical information technology, etc. Many fields of application require a uniform beam of light to illuminate the target. [0003] At p...
