Description

Technical Field

[0001] The invention relates to an optical axis calibration device and method, and in particular to a fast calibration device and method for detecting an optical axis using an aspherical mirror. Background Art

[0002] During the installation, debugging and testing phase of aspheric mirrors, the size of the aspheric mirror's surface parameters is an important indicator parameter to ensure the image quality and function of the system. The smaller the surface, the better the imaging effect, the closer the system function indicators are to the design indicator requirements, and the better the product quality.

[0003] How to accurately and quickly obtain the surface parameters of the aspheric mirror after processing and after gluing is the focus of the installation personnel. Existing aspheric mirrors are generally equipped with compensators during detection, but when the compensator cannot image an infinitely far object, the return light spot cannot appear on the interferometer. As a result, during the installation and detection stage, the 18 degrees of freedom of the interferometer, compensator and aspheric mirror make it impossible for the three optical axes to quickly achieve high-precision coaxial calibration, making the installation and detection of aspheric mirrors time-consuming and laborious.

[0030] At the same time, the present invention also provides a method for quickly calibrating an optical axis of an aspherical mirror, which is special in that it includes the following steps:

[0031] Step 1: Install a standard plane lens at the exit plane of the interferometer, adjust the interferometer so that the light spot of the standard plane lens is located at the center of the cat's eye of the interferometer, then adjust the theodolite to the ground level and perform self-alignment on the standard plane lens, transfer the interferometer's posture to the theodolite, and remove the standard plane lens;

[0032] Step 2, set the first lifting frame and the support rod between the interferometer and the theodolite, install the first cantilever on the support rod, and install the plane reflector on the back of the first cantilever, adjust the position and posture of the first cantilever so that the image reflected by the plane reflector falls on the cross center of the theodolite, and remove the plane reflector; the back is the side opposite to the theodolite;

[0033] Step 3, install the second cantilever on the support rod, and install the plane reflector on the back of the second cantilever, adjust the position and posture of the second cantilever so that the image reflected by the plane reflector falls on the center of the theodolite cross, and remove the plane reflector;

[0034] Step 4, install a standard spherical lens on the interferometer, adjust the interferometer so that the light spot of the standard spherical lens is located at the center of the cat's eye of the interferometer, install a light spot analyzer on the first cantilever, make the photosensitive surface of the light spot analyzer face the focus of the standard spherical lens, record the center position of the focus, and then remove the light spot analyzer;

[0035] Step 5, install the compensator assembly on one side of the support rod, install the plane reflector on the end face of the compensator opposite to the theodolite, install the spot analyzer on the second cantilever, make the photosensitive surface of the spot analyzer opposite to the focus of the standard spherical lens, adjust the compensator until the focus position measured by the spot analyzer again is the same as the focus position recorded in step 4, and at the same time, the image reflected by the plane reflector is located at the cross center of the theodolite; Step 6, remove the plane reflector, dismantle the spot analyzer, the first lifting frame and the support rod, install the support tooling, install the aspheric mirror to be tested on the support tooling, and install the plane reflector on the back of the aspheric mirror to be tested;

[0036] Step 7: Adjust the tilt posture of the aspheric mirror to be tested by the supporting fixture so that the image reflected by the plane reflector coincides with the cross center of the theodolite. At the same time, the light emitted by the interferometer passes through the compensator and the aspheric mirror to be tested in sequence, and then returns to the interferometer through the compensator. The light spot is located at the center of the cat's eye of the interferometer, and the coaxial calibration of the optical axis is completed.

[0037] Furthermore, in step 5: when installing the compensator assembly, a laser rangefinder is used to measure the distances between the compensator and the interferometer and the aspheric mirror to be measured, respectively, so that the two distances meet preset values.

[0038] Beneficial effects of the present invention:

[0039] 1. The present invention sets a fixed tooling assembly between the interferometer and the theodolite. The spatial posture of the interferometer can be transferred to the theodolite by observing the autocollimation image of the interferometer through the theodolite. The optical path between the interferometer and the theodolite is divided into two sections by a compensator. The light spot analyzer is used to ensure the front and rear concentricity of the light of the interferometer through the compensator, so as to calibrate the optical axis of the aspheric mirror detection, and quickly connect the divided optical paths together, so as to quickly and effectively calibrate the coaxial optical axes of the interferometer, the compensator and the aspheric mirror, which greatly saves the installation time.

[0040] 2. The present invention utilizes a spot analyzer for dynamic debugging and uses an optical method to calibrate the optical axis throughout the entire process, and has the technical characteristics of simple installation and detection and high reliability.

[0041] 3. The present invention uses a guide rod plus a slider to adjust the distance between the first cantilever and the second cantilever, so that the position of the spot analyzer can be adjusted forward and backward according to actual conditions during calibration, and has a wide range of applications.
