Abstract
The utility model relates to a multiple optical axle closed-loop control device for stabilizing multiple optical axles on a same target surface. The multiple optical axle closed-loop control device comprises two fast steering mirrors, a reflection mirror, a spectroscope, a target surface, a detector, a CCD, an image processor, and a PID controller for controlling the fast steering mirrors, wherein each fast steering mirror receives and reflects one optical path, the optical path reflected by each fast steering mirror is adjusted by the reflection mirror and finally projected on an optical path collection reflection mirror, and each optical path is reflected on the spectroscope by the optical path collection reflection mirror and split. The structure of the device is simplified, and the detection cost and control cost are reduced. Meanwhile, multiple optical spots on the target surface are arbitrarily arranged or combined into one optical spot, and easy to implement.
Description
Technical field
The utility model belongs to stablizes the optical axis technology in the optical system, be specifically related to a kind ofly in the control of multi-beam stabilizer shaft, the multi beam optical axis is carried out real-time closed-loop proofread and correct, with the multi beam optical axis closed-loop control device of multi-beam stabilizer shaft on same target surface.
Background technology
In the optical system of complexity, usually the multi beam light path can occur simultaneously, and the optical jitter of every beam optical path all needs to carry out stability control.At present, known optical axis stable control is all adopted fast anti-mirror to carry out real-time closed-loop and is proofreaied and correct to realize, for the multi beam light path system, basically all be to take the corresponding detection system of a light path and a cover closed-loop control system, it is relatively poor that every beam optical path points to the controllability of same target simultaneously, and detection system and closed-loop control system are more, and it is surveyed cost and controls cost higher.In actual applications, closed-loop control and the arrangement mode of multi beam optical axis on the target target surface are unmanageable when the multi beam optical axis.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of in the control of multi-beam stabilizer shaft, the multi beam optical axis is carried out real-time closed-loop proofread and correct, the multi-beam stabilizer shaft on same target surface, and is adopted cover detector and a closed loop controller multi beam optical axis closed-loop control device.
Solution of the present utility model is: a kind of multi beam optical axis closed-loop control device, comprise and receive the also fast anti-mirror of reflected light path, adjust the catoptron of light path, light path is divided into two-part spectroscope, the target target surface that light path is aimed at, survey the detector of the target target surface of light path aligning, detection is carried out the CCD of imaging, the image processor of imaging processing is controlled the PID controller of fast anti-mirror, is characterized in that fast anti-mirror is at least two, every fast anti-mirror reception is also reflected a light path, the light path of every fast anti-mirror reflection finally projects light path and compiles on the catoptron by its reflector alignment light path, and light path is compiled catoptron each road light path is reflexed to light splitting on the spectroscope.
Control procedure of the present utility model is: the light path that every bundle light forms projects light path through the light of fast anti-mirror reception and reflection, fast anti-mirror reflection through the reflector alignment light path and compiles on the catoptron, light path is compiled catoptron each road light path is reflexed to light splitting on the spectroscope, a part is divided to the target target surface, and another part divides to detector.Divide to the transmitted light of detector to enter on the detection target surface CCD, process being input to the optical axis that the PID controller is controlled respectively each fast anti-mirror through image, final control projects position and the arrangement of target target surface hot spot.
More excellent scheme is that fast anti-mirror is four in the solution of the present utility model, and four tunnel light paths are by fast anti-mirror one, fast anti-mirror two, fast anti-mirror three, fast anti-mirror four reflections, and catoptron corresponding to each fast anti-mirror reflexes to light path and compile on the catoptron the light path adjustment.
Detector adopts oblique mirror light splitting in the solution of the present utility model, and dot projection is arrived CCD.Its objective is and be convenient to the CCD imaging, reduce device volume.
Advantage of the present utility model: because the utility model adopts fast anti-mirror to be at least two, every fast anti-mirror reception is also reflected a light path, the light path of every fast anti-mirror reflection is by its reflector alignment light path, finally projecting light path compiles on the catoptron, light path is compiled catoptron each road light path is reflexed to light splitting on the spectroscope, proofread and correct so adopt cover detector and a closed loop controller to carry out real-time closed-loop to the multi beam optical axis, with the multi-beam stabilizer shaft on same target surface.The utility model designs simplification, reduction is surveyed cost and is controlled cost, and simultaneously, the multi beam hot spot can arbitrary arrangement or synthetic hot spot, easily realization on the target target surface.
