Description
Technical field
This novel regulating device that belongs to is specifically related to a kind of optical adjustment device of Laser Detecting Set.
Background technology
Existing Laser Detecting Set; Comprise that range finder using laser, laser radar, laser active homer etc. have the active laser sniffer of emission, receiving function; Because the directionality characteristic of laser, the collimation that all can face Laser emission light path and receiving light path is regulated problem.For the Laser Detecting Set of operating distance more than 1km; The Laser emission that adopts at present, reception field angle are generally the mrad level; Receive field angle and also have only about several mrad with the differential seat angle of launching field angle, parallel accuracy requires very high, but because the processing of device and optical element and assembling equal error; Can not directly guarantee Laser emission, receiving light path parallel through machining, need to adopt governor motion to regulate and reach two light path parallels.
Existing regulating measure generally is two kinds of methods; A kind of method is to regulate light path through the relative position of regulating emission, receiving-member; Can readjust the distribution and penetrate parts, also can transfer receive parts, but the Laser Detecting Set of heat radiation requirement arranged for laser instrument; Usually regulate the laser pick-off parts, governor motion comprises adjustment rack, ball adjusting etc.Another kind method is to regulate radiation direction, and usual way is that the direction that adopts plane mirror to change emission light path or receiving light path reaches the parallel of two light paths.
Above method all need design governor motion.Because optical system has nothing in common with each other; The space difference that can be used to design governor motion is very big; Therefore in the design of the Laser Detecting Set of each mrad visual field, the design of light path parallel governor motion all needs to design again, wastes time and energy; And the adjustment structure of usually design debugs also cumbersomely, and resistance to shock is poor.
Summary of the invention
The utility model provides a kind of adjusting simple, the optical adjustment device of the Laser Detecting Set that anti-seismic performance is good to the defective of prior art.
Summary of the invention: a kind of optical adjustment apparatus structure; The fixed mounting that comprises cylinder type; The install adjustment sleeve of socket cylinder type outside fixed mounting; External diameter is set in the internal diameter of regulating sleeve regulates mount pad and preceding wedge shape mirror adjusting mount pad less than the back wedge shape mirror of the cylinder type of install adjustment sleeve, wedge shape mirror adjusting mount pad is regulated in the mount pad with preceding wedge shape mirror identical back wedge shape mirror and preceding wedge shape mirror is set in the back.
The effect of the utility model is: have advantages such as universalization, seriation, and simple in structure, take up room for a short time, can be used in the various Laser Detecting Set, regulative mode is easy, degree of regulation is high, good anti-vibration.
Description of drawings
Fig. 1 is the optical adjustment apparatus structure synoptic diagram of the Laser Detecting Set that provides of the utility model;
Fig. 2 is the synoptic diagram that the B point is adjusted to the A process.
Among the figure: 1. fixed mounting, 2. the install adjustment sleeve, 3. back wedge shape mirror regulate mount pad, 4. back wedge shape mirror, 5. before the wedge shape mirror, 6. before the wedge shape mirror regulate mount pad.
Embodiment
Shown in accompanying drawing 1; A kind of optical adjustment apparatus structure; The fixed mounting 1 that comprises cylinder type; The install adjustment sleeve 2 of socket cylinder type outside fixed mounting 1 is provided with external diameter and regulates mount pad 3 and preceding wedge shape mirror adjusting mount pad 6 less than the back wedge shape mirror of the cylinder type of install adjustment sleeve 2 in the internal diameter of regulating sleeve 2, wedge shape mirror adjusting mount pad 3 is regulated with preceding wedge shape mirror identical back wedge shape mirror 4 and preceding wedge shape mirror 5 are set in the mount pad 6 in the back.
This novel optical adjustment Unit Installation order is as follows: (back wedge shape mirror 4 bonds to back wedge shape mirror respectively with preceding wedge shape mirror 5 and regulates on mount pad 3 and the preceding wedge shape mirror adjusting mount pad 6 with the wedge shape mirror earlier; After treating bonding curing; Back wedge shape mirror adjusting mount pad 3 is screwed into from install adjustment sleeve 2 two ends respectively with preceding wedge shape mirror adjusting mount pad 6; Will back wedge shape mirror regulate that mount pad 3 spinnings put in place and fastening with holding screw, then with install adjustment sleeve 2 through in screw thread and the positioning cylindrical surface screw-in fixed mounting 1.At last fixed mounting 1 is connected firmly at the generating laser front end, can carry out next step light path and regulate.
Principles of Regulation and control method are following: if the wedge shape mirror is regulated the connecting thread between mount pad 6 and the regulating sleeve 2 before tuning; Two wedges have and relatively rotate, after laser is regulated parts through this, perpendicular to being projected as from inside to outside or from outside to inside a helix on the plane of optical axis; As shown in Figure 2; If learn that according to the laser pick-off light path subpoint of emission laser on this plane after mixing up is the A point, then need preceding wedge shape mirror be regulated mount pad 6 and tune when luminous point arrives B and no longer tuning, change into and tune being threaded between regulating sleeve 2 and the fixed mounting 1; Make two wedge shape mirrors along with regulating sleeve 2 rotates simultaneously together; Luminous point will be drawn a circle around the A point, and at this moment the hot spot drop point might not be fallen on the A point, and wedge shape mirror adjusting mount pad 6 and 2 of regulating sleeves is threaded before at this moment repeating to adjust; Change the relative position of B point position and two wedge shape mirrors; Recruiting, screw thread is drawn a circle the light drop point between regulating sleeve 2 and the fixed mounting 1 again, and so repeated multiple times can finally be transferred to A point position with laser facula.
