Fig. 1 shows a kind of high-level schematic functional block diagram of optical system provided in an embodiment of the present invention, and Fig. 2 shows thisInventive embodiments provide the structural representation in a kind of optical system practice, and for convenience of description, the present embodiment only illustratesThe part related to present invention.
In embodiments of the present invention, optical system 100 includes：Dichroic mirror 110, image receiving unit 120, Laser emissionUnit 130, details are as follows：
As one embodiment of the present of invention, dichroic mirror 110 is used for reflecting specific wavelength light, and makes except specific wavelengthOther wavelength light outside light pass through.
As a practice of the present invention, the angle between dichroic mirror 110 and horizontal plane is preferably 45 degree, not onlyIn the target zone object reflected light fully reflective entrance image receiving unit 120 that wavelength can be made consistent with preset wavelength, increasePlus image receiving unit 120 imaging precision；At the same time it can also be ensured that the reception optical axis of image receiving unit 120 and horizontal planeIn an angle of 90 degrees, so that the Aspect Ratio of image and actual Aspect Ratio is coincide, and then avoid image distortion to occur, to target objectPosition judgment produces error, improves the degree of accuracy that whole system catches to target object.
In other embodiments of the present invention, the angle between dichroic mirror 110 and horizontal plane can also be 35 degree, 40 degree,50 degree etc., specifically do not limit.
As a preferred embodiment of the present invention, the laser of laser emission element transmitting and dichroic mirror 110 reflectionTarget zone object reflected light is different wavelengths of light, and it is determined by the characteristic of dichroic mirror 110 itself.As laser emission elementThe wavelength of the laser beam of transmitting is 960nm, then the laser beam of 960nm can be completely through dichroic mirror 110, and strike is hitTarget object；And the wavelength of the target zone object reflected light through dichroic mirror 110 reflection is 480nm, then the target model of 480nmEnclose object reflected light fully reflective through dichroic mirror 110, and then target object is positioned.
Image receiving unit 120, for receiving the target zone object with preset wavelength being reflected by dichroic mirror 110Reflected light, forms image information and exports, to obtain the positional information of target object according to image information.
Referring to Fig. 3, as one embodiment of the present of invention, image receiving unit 120 includes：Image receives microscope group 121, filterLight part 122, photo-sensitive cell 123.
As a preferred embodiment of the present invention, image is received microscope group 121 and is matched with photo-sensitive cell 123, by targetIn scope object guides reflected light photo-sensitive cell 123.In practice, image receives microscope group 121 and typically adopts plastic lens, glassGlass lens etc., specifically can be matched according to user's request.
As a preferred embodiment of the present invention, optical filtering part 122 receives microscope group 121 located at photo-sensitive cell 123 with imageBetween, for only making to there is the target zone object reflected light of preset wavelength by, for example, only permission infrared light returns through targetIt is imaged to sensitive piece 123, and then the foreground moving object object in the prominent visual field, and ambient light can be eliminated to target imagingImpact；Meanwhile, equipment can be made lighter, equipment of saving uses, manufacturing cost.
As a preferred embodiment of the present invention, photo-sensitive cell 123, for reflecting the target zone receiving objectLight forms image information, and e.g., photographic head, video camera etc. have the equipment of imaging function of taking pictures.
Laser emission element 130, for the positional information according to target object, through dichroic mirror 110 to target objectCarry out Laser emission；Wherein, the Laser emission optical axis of laser emission element 130 and the reflected light of target zone object reflected light connectReceive optical axis coaxial.
Referring to Fig. 4, in embodiments of the present invention, laser emission element 130 includes：Laser instrument 131, optical path-deflecting module132.
Referring to Fig. 5, as a preferred embodiment of the present invention, laser instrument 131 includes：Laser generating element 1311, usesIn generation laser beam；And launch the collimation microscope group 1312 in light path located at laser generating element 1311, wherein, collimate microscope group1312 include at least two for the cylindrical mirror that laser is collimated, and laser generating element 1311 can be produced by collimation microscope group 1312Raw non-directional laser beam, the reference line directional transmissions being formed through space, make the collimating effect of laser more preferably, improve to meshThe seizure of mark object, strike precision.
As a preferred embodiment of the present invention, optical path-deflecting module 132, for the laser optical path that laser instrument is launchedEnter horizontal deflection, it includes at least one piece reflecting mirror or prism.In practice, user can adjust rib according to practical situationMirror angle, that is, pass through to control optical path-deflecting module 132, make laser beam accurately hit the direction being located in target object, make to swashLight device 131 structure design more optimizes.
Optical system provided in an embodiment of the present invention, by designing Laser emission optical axis and the target model of laser emission elementThe reflected light reception optical axis enclosing object reflected light is coaxial, and then improves precision and the reliability that optical system is hit in real time；WithWhen, transmitting-receiving coaxial system design can make device structure simpler, and lightweight and portable in volume reduces design and the manufacturing cost of laser radar.
