Abstract
The utility model discloses a collimation device capable of controlling a spot size, which comprises an illumination light source, a collimation component, a controller and an imaging square lens. The collimation component is electrically connected with the controller, light transmitted by the illumination light source irradiates an object through the collimation component to form a spot, an image is formed through the imaging square lens when the light is reflected by the object, and the imaging square lens adopts a zoom lens with position feedback information and is mechanically connected with the collimation component. The controller obtains corresponding position data of the collimation component on a relatively appropriate spot size according to the position feedback information of the zoom lens (i.e. field feedback information), and drives the collimation component to reach a corresponding position, thus coupling of zoom and the spot is realized automatically. The controller can also drive the collimation component according to manual input to realize manual control of the spot size.
Description
Technical field
The utility model relates to field of photoelectric technology, relates in particular to a kind of collimator apparatus of controlling spot size.
Background technology
Follow the development of night vision technology, had the collimation that has zoom function on the market, and what adopt is the power zoom mode, adopt the zoom mode of this mode to can be good at being applied in the security protection equipment.
What a kind of collimator apparatus of existing control spot size adopted is artificial control, needs operating personnel and observes the hot spot suitable spot size of controlling illumination whether in the image.This device is higher to people's dependence, can not realize automatic control.But this device advantage be that the effect of throwing light on is best because the effect that the people observes is exactly actual result of use.Adopt this zoom mode to can be good at being applied in the security protection equipment, the hot spot that operating personnel can control collimation very easily at control desk goes to mate with the imaging viewing field angle of lens, thereby obtain best image, it is greatly convenient that this collimator apparatus has brought to operating personnel, but also brought trouble simultaneously to operating personnel, because regulated after the focal length of lens, must regulate spot size.
The collimator apparatus of existing interlock zoom control spot size, it is taked is artificially some field conditions to be carried out some simulations, the data writing controller that obtains by simulation is controlled thereby realization is automatic then.The advantage of this control is to realize automatic control.Though this control mode has realized interlock control, can not be change spot size manual when hot spot is inappropriate.
The utility model content
For overcoming the defective of prior art, the technical problems to be solved in the utility model has provided a kind of collimator apparatus that makes hot spot and zoom link, both can also can manually control automatically spot size.
The technical solution of the utility model is: the collimator apparatus of this control spot size, comprise the collimating components of lighting source, electrical connection and controller, as square lens, shine object from the light of lighting source emission through collimating components and form hot spot, then light by after the object reflection through picture side's lens imaging, as square lens are the zoom lens that carry position feedback information, and it mechanically links to each other with collimating components.
Controller obtains the correspondence position data of the collimating components of suitable relatively spot size according to the position feedback information (also being the visual field feedback information) of zoom lens, the controller drives collimating components arrives this correspondence position then, thereby automatically realize the interlock of zoom and hot spot, controller also can drive collimating components according to manual input, thereby realizes manually controlling spot size.
Description of drawings
Fig. 1 is the synoptic diagram of the collimator apparatus of control spot size of the present utility model.
Embodiment
Fig. 1 is the synoptic diagram of the collimator apparatus of control spot size of the present utility model.The collimator apparatus of this control spot size, comprise lighting source 1, the collimating components 2 that is electrically connected and controller 3, as square lens, passing through collimating components 2 from the light (straight line by no arrow is represented) of lighting source 1 emission shines object 4 and forms hot spot 41, then light by object 4 reflection after through picture side's lens imaging, as square lens are the zoom lens 5 that carry position feedback information, its mechanically link to each other with collimating components 2 (being the two interlock).Controller 3 (also is visual field 51 feedback informations according to the lens position signal of zoom lens 5, straight line by the band arrow is represented), obtain the correspondence position data of the collimating components of relative suitable spot size by hot spot 41 and corresponding relation as square visual field, the collimation position signal (straight line by the band arrow is represented) that these correspondence position data and collimating components 2 are sent into controller 3 relatively, if identical then collimating components is motionless, otherwise controller 3 will be controlled collimation motor signal (straight line by the band arrow is represented) and send to collimating components and arrive these correspondence positions to drive collimating components 2.Effect at body surface is: when visual field 51 became big, it is big that hot spot also becomes thereupon, thereby automatically realize the interlock of zoom and hot spot, Zhun Zhi interlock just.Controller 3 also can obtain the correspondence position data of the collimating components of relative suitable spot size according to the position feedback information of manual input (not shown in figure 1) by the hot spot and the corresponding relation of field angle of image, controller 3 drives collimating components 2 and arrives this correspondence position then, thereby realizes manually controlling spot size.
Preferably, lighting source 1 is a laser driver.
Further, laser driver is the laser driver of emission λ=0.76-3 μ m.Collimator apparatus of the present utility model so just can be used for night vision system.
Preferably, described controller is a single-chip microcomputer.
Further, described single-chip microcomputer comprises toggle switch, and it comprises startup/forbidding part, debugging part.Startup/forbidding part is according to daytime and night forbidding or enable the control of collimation zoom.Debugging part is at different lens design, can be determined the maximum hot spot and the minimum hot spot of collimation under not needing again to the situation of single-chip microcomputer programming program by the user.
Preferably, described single-chip microcomputer comprises A/D converter.For example, be digital signal after adopting 10 A/D converter that potentiometer is gathered with analog signal conversion, make precision reach 1/1024.
There is not mechanical part in the pure design of electronic circuits that controller of the present utility model adopts, and circuit part also adopts photoelectricity to isolate in addition, has very high reliability.
In addition, zoom lens 5 can closely mechanically be connected with collimating components 2.
Whether singlechip controller moves by the zoom of detector lens, if detect the camera lens action, gather the position signalling of camera lens zoom then, obtain the size of laser facula by the relation of this position and hot spot, control the collimation action by more present spot size then, realize interlock.If local feature just adopts manually control.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; every foundation technical spirit of the present utility model all still belongs to the protection domain of technical solutions of the utility model to any simple modification, equivalent variations and modification that above embodiment did.
