Description
Technical Field
The invention relates to the technical field of optical-mechanical adjustment, which can add an auto-collimation function to the existing collimator without the auto-collimation function in a laboratory, and ensure the collimation of emergent light of a product debugged by using the collimator and the collimator.
Background
The collimator is mainly used for producing parallel light beams, is an important tool for assembling and adjusting the optical instrument, and is also an important component in an optical measuring instrument.
Part of the collimator is mainly used for simulating infinite targets, a debugged product can receive the targets, but for many debugging scenes, it is required to ensure that the parallel light enters the product at a normal incidence angle, that is, the collimator is provided with an auto-collimation device, and the angle of the returned parallel light can be received through the auto-collimation device, so that the installation posture information of the product can be captured.
At present, the collimator with the auto-collimation function is mainly divided into two types, one is to install an auto-collimation device at the rear end of a target plate of the collimator, and the other is to adopt a mode of cutting a semi-transparent and semi-reflective mirror into a convergent light path, and to divide the light path into one path to focus and image in the auto-collimation device. For the collimator without the auto-collimation function, the two modes both need to change the optical-mechanical structure of the original collimator, otherwise, the auto-collimation function is difficult to realize.
For many debugging scenes, it is necessary to ensure that the parallel light enters the product at a normal incidence angle, i.e. the collimator is required to be provided with an auto-collimation device. For the collimator without the auto-collimation function, the addition of the auto-collimation device needs to change the optical-mechanical structure of the original collimator, so that the external auto-collimation receiving device needs to be invented, the internal structure of the original collimator does not need to be changed, the existing collimator can be quickly modified, the auto-collimation function is added, the production cost is reduced, and the product quality is improved.

Detailed Description
The invention is further illustrated with reference to the following figures and examples.
The technical scheme of the invention is as follows: the external auto-collimation receiving device is arranged at the outlet of the collimator, and the pyramid prism is used for calibrating the auto-collimation position, so that the collimator is added with the auto-collimation function
An external auto-collimation receiving device comprises a CCD, a converging mirror group component, a standard reflector, a collimator and a semi-transmitting semi-reflecting mirror, wherein the semi-transmitting semi-reflecting mirror is positioned in front of the collimator, parallel light emitted by the collimator enters a pyramid prism after passing through the semi-transmitting semi-reflecting mirror, the pyramid prism returns incident light beams to the semi-transmitting semi-reflecting mirror, the light beams enter the converging mirror group component after being reflected by the semi-transmitting semi-reflecting mirror and the standard reflector, and the converging mirror group component converges the light beams entering after being reflected by the standard reflector on a CCD image surface for imaging.
The pyramid prism emits the incident beam according to the original angle and returns the incident beam to the half-transmitting and half-reflecting mirror at the same angle.
The invention can not affect the parallel light emitted by the collimator by installing the semi-transparent semi-reflecting mirror at the outlet of the collimator, the semi-transparent semi-reflecting mirror reflects the parallel light returned from the product into the convergent eyepiece and finally received by the CCD, the whole device is arranged at the periphery of the original collimator, and the self structure and performance of the collimator can not be affected.
The adjusting method of the external self-aligning direct receiving device comprises the following steps:
step 1: the semi-transparent semi-reflecting mirror is initially fixed in front of the collimator, and is arranged in a non-central area of a light-passing aperture of the collimator in order to ensure that the emergent light beam of the collimator is not influenced as much as possible.
Step 2: the converging lens group component, the standard reflector and the CCD are arranged in place, so that the converging lens group can focus incident parallel light on a CCD image surface.
And step 3: and then calibration is carried out. The pyramid prism is placed in front of the semi-transparent semi-reflective mirror, so that parallel light emitted by the collimator can enter the pyramid prism after passing through the semi-transparent semi-reflective mirror.
And 4, step 4: the pyramid prism returns the incident beam to the semi-transparent and semi-reflective mirror in the same angle, and the beam enters the converging mirror assembly after being reflected by the semi-transparent and semi-reflective mirror and the standard reflector in sequence.
And 5: the converging lens group component converges the light beam reflected by the standard reflecting mirror on a CCD image surface for imaging.
Step 6: the position and the angle of the CCD are finely adjusted, so that the target of the collimator tube can clearly image on the CCD image surface. The current imaging clear position is the auto-collimation zero position of the auto-collimation direct receiving device.
If the CCD cannot capture the target, the error of the installation angle of the semi-transparent semi-reflecting mirror and the standard reflecting mirror is too large, the light beams cannot be reflected into the converging mirror group, the angle of the semi-transparent semi-reflecting mirror and the angle of the standard reflecting mirror need to be finely adjusted until the target is clearly imaged on the CCD image surface, and then the installation angle of the semi-transparent semi-reflecting mirror and the installation angle of the standard reflecting mirror are fixed.
And 7: and after calibration is finished, taking down the pyramid prism.
And 8: when the collimator is used for assembling and adjusting products, the products needing auto-collimation are placed in front of the collimator, and the products can simultaneously receive light beams directly emitted by the collimator and light beams penetrating through the half-transmitting and half-reflecting mirror.
And step 9: and a tool reflector is arranged on the vertical reference surface of the product, so that the light beam penetrating through the semi-transparent semi-reflective mirror is reflected by the tool reflector to return to the semi-transparent semi-reflective mirror, then reflected by the semi-transparent semi-reflective mirror to reach the standard reflector, and finally imaged on the CCD image surface.
Step 10: the imaging position of the target of the collimator in the CCD is coincided with the calibrated auto-collimation zero position by fine tuning the posture of the product. At the moment, the angle of the tooling reflector is perpendicular to the angle of the parallel light emitted by the collimator, namely, the parallel light enters a product at a normal incidence angle, and the product and the collimator reach a self-collimation state.
