Embodiment Construction

[0009] The implementation of the present invention is used to produce the coaxial method of the inner and outer conical mirrors of the hollow light beam. The specific embodiment is as follows, as Figure 5 shown. At first, on the display 1, display the standard bull's-eye of assembly: the display device 1 is preset as the display device of the CCD image sensor 3 by the character superposition module program; the character superposition module 2 is connected between the CCD image sensor 3 and the display 1, by The program of the character overlay module designates the center of the pixel array of the CCD image sensor 3 as the center of the optical image, and displays it on the display 1 as the bull's-eye of the adjustment reference. Secondly, establish a reference light path: the light path given by the laser 4 is collimated by the telescopic system 5 and then divided into two beams whose optical paths are perpendicular to each other by the half-mirror 6. The light path is He-N...

Abstract

The invention discloses a method for realizing coaxiality of inner and outer cone mirrors for producing hollow beams, belongs to the field of optical technology and aims to solve the problem that an inner and outer cone mirror optical system alignment technology is absent in the prior art. The method comprises the following steps: firstly, a character superimposition module program assigns pixel array centers of CCD (charge coupled device) image sensors to be centers of optical images, and the pixel array centers serving as alignment datum bull's-eyes are displayed; secondly, alignment light is collimated and divided into two beams with mutually perpendicular light paths, then the light is focused and imaged on the CCD image sensors on respective light paths through positive lenses on the respective light paths, obtained alignment light image electric signals are transmitted to a display to be displayed as alignment light images, and the positions of the two positive lenses are adjusted respectively in the horizontal direction and the vertical direction, so that the alignment light images move to the alignment datum bull's-eyes; thirdly, the to-be-aligned inner and outer cone mirror optical system is mounted on an alignment light path, and the positions of the inner cone mirror and the outer cone mirror are adjusted respectively in the horizontal direction and the vertical direction until the alignment light images move to the alignment datum bull's-eyes.

Description

technical field [0001] The invention relates to a method for realizing the coaxiality of the inner and outer conical mirrors used to generate hollow light beams, which is applied to the installation and adjustment of the inner and outer conical mirror optical systems, so that the respective geometric axes of the inner and outer conical mirrors are coaxial with the common optical axis The method for avoiding the deformation of the hollow light beam generated thereby belongs to the field of optical technology. Background technique [0002] A hollow beam (hollow laser beam) is a ring-shaped beam with zero central light intensity in the propagation direction, and has many special physical properties, such as barrel-shaped intensity distribution, small dark spot size (DSS) and propagation invariance, And has spin and orbital angular momentum, etc. As a laser catheter, optical tweezers (optical tweezers) and optical wrench, the hollow beam has become a powerful tool for precise m...
