Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.
Referring to figs. 1 through shown in Figure 4, visual laser pickoff of the present utility model comprises: one group of above photosensitive array 1, controller, visualization interface 2.Controller drives photosensitive array 1 also receives its feedback signal, and visualization interface 2 is simulated measured laser with visual pattern under controller control; Controller is electrically connected with visualization interface 2, photosensitive array 1 formation.
Wherein photosensitive array 1 comprises a plurality of photosensitive units, and these photosensitive units can be CCD chip, CMOS chip or PSD chip photovalves such as (Position Sensitive Detector, position sensitive detectors).Visualization interface 2 is meant the human-computer interaction interface that can offer user's visual image, and as preferably, visualization interface 2 comprises: the display screen 201 that is used to show, be used to the control panel 202 controlling and import.
As a kind of preferred version, the number of the photosensitive array 1 that is become by the photosensitive unit line spread is 2, be separately positioned on the both sides of visualization interface 2, so, when lasing area A can project on such two photosensitive arrays 1, photosensitive array 1 corresponding photosensitive unit survey to laser beam, the position of result that controller is surveyed according to photosensitive array 1 and concrete photosensitive unit normally is incident upon line segment on the visualization interface 2 at the image line segment simulated laser face A that shows with display screen 201 on the visualization interface 2, concrete way is, controller determines that at first both sides photosensitive array 1 detects the specific position of lasing area A, controller control display demonstrates a line segment pattern (because restriction of display screen 201 screen sizes) then, and this line segment pattern promptly is that lasing area A is incident upon the visual pattern on the display screen 201.
Need to prove, the left and right sides of said here visualization interface 2, be meant the relative both sides of visualization interface 2 interface zones, when the lasing area A to level measures, we wish or we make photosensitive array 1 be positioned at the both sides of the level of visualization interface 2 by setting, promptly left, right both sides, the straight-line segment that this moment, the photosensitive unit arrangement formed is parallel to vertical direction, lay respectively at the left and right sides of visualization interface 2, this moment, the lasing area A of level needed only in the scope of photosensitive array 1, must be displayed on the visualization interface 2, certainly we can be by adjusting the whole height position that visualization interface 2 and photosensitive array 1 constitute, aim at lasing area A, when even the straight-line segment that forms in the photosensitive unit arrangement departs from vertical direction slightly certainly, as long as lasing area A can be radiated on the photosensitive array 1 simultaneously, visualization interface 2 still can imaging show the line segment of representing lasing area A, just also deflection of visualization interface 2 this moment, may make us can't finish the work of correction, so we still wish the lasing area A(of reception level or according to measuring that purpose is wanted the realization level and the lasing area A that needs receiver to proofread and correct) time, we need ajust the integral body of visualization interface 2 and photosensitive array 1 formation, make photosensitive unit arrange the straight-line segment that forms and are parallel to vertical direction.
To vertical lasing area A(or according to measuring that purpose is wanted the realization level and the lasing area A that needs receiver to proofread and correct), we still adopt relative both sides that linear pattern photosensitive array 1(is set promptly to constitute photosensitive array 1 by a row photosensitive unit of line spread in fact, scheme down together), only in order to detect vertical lasing area A, we wish it is vertical both sides these both sides, and this can realize also can being used for realizing by aforementioned schemes rotation 90 degree are made by photosensitive array 1 being arranged on vertical both sides.
For in the reality, when not only having had the lasing area A of level but also having existed vertical laser all to need to receive simultaneously, as a kind of preferred version, the number of photosensitive array 1 is 4, is separately positioned on the four direction of visualization interface 2; Just be equipped with photosensitive array 1 at two couple of visualization interface 2 four direction facing each other.
As further preferred, visualization interface 2 has the profile of rectangle, and the linear pattern photosensitive array 1 around it all is parallel to the outline line of visualization interface 2 tools of its place side.
In order after visualization interface 2 shows lasing area A position, to realize calibration operation, as a kind of preferred version, in laser pickoff of the present utility model, also comprise: calibrating installation 3.Particularly, calibrating installation 3 can be that mechanical bubble also can be an Electronic bubble, if Electronic bubble, then it realizes being electrically connected with controller.
When specifically carrying out work, at first pass through the position of calibrating installation 3 calibration visualization interfaces 2, make its object of reference as reference standard, carry out level or vertical location such as scale line (can be scale in kind constitute also can be the virtual line segment that display screen 201 shows) etc., further go to the position of calibration of laser face A then by them.
As a kind of preferred version, the display screen 201 of visualization interface 2 is a dot matrix display screen, under the situation of lasing area A that has calibrating installation 3 and determine to be received for definite surface level or vertical plane, a photosensitive array 1 can only be set, because this moment is in known laser face A level or when vertical, only need a point can be identified for representing its virtual line segment, what adopt for the lasing area A of level is vertical linear pattern photosensitive array 1, for the vertical linear pattern photosensitive array 1 that then adopts level, in addition, display screen 201 can adopt the segment encode display screen, during reception, by putting the segment encode level that makes the segment encode display screen or vertically.
Need to prove, when having a plurality of levels to launch lasing area A simultaneously, controller can judge whether a plurality of laser rays that detected by photosensitive unit belong to same lasing area A, it only can demonstrate line segment with the some position that belongs to same lasing area A on screen, different line segments can be by screen gray scale, color, thickness etc. go to distinguish and show, can't discern and estimate of situation when running into, can adopt in the flicker of the corresponding position of screen edge, judge voluntarily or adjust laser surveying instrument such as level with the prompting user.
Its middle controller can judge whether a plurality of laser rays that detected by photosensitive unit belong to same lasing area according to difference such as Wavelength of Laser, signal amplitude, pulsed frequencies.For example, utilize the difference of signal amplitude, when the multi-stripe laser line is got on the photosensitive array, because the distance distance is the factor of laser power, cause different laser rays difference to be arranged, and the relative amplitude of same laser line on different photosensitive arrays is constant at signal amplitude, therefore, by the judgement of relative signal amplitude, just the signal on the different photosensitive arrays can be matched, thereby can draw many lines.By the power of amplitude, the thickness and the shade that change lines show on display screen 201 again.Wherein under monochromatic display screen, can distinguish different lines,, can distinguish different lines by grayscale table having under the monochromatic display screen of gray scale with the thickness of lines.
Can certainly discern by the mistiming of laser rays, the mistiming is meant that pulse generating time is inconsistent, can judge the priority of light, whether belongs to same lasing area A thereby distinguish a plurality of laser rays.Under the pulse laser condition, display screen 201 also can promptly can be distinguished by the line of flicker or the line that continues to show by the different linear different lasing areas that show respectively.In sum, visual laser pickoff of the present utility model can manifest laser position intuitively, in real time, and the restriction in non-angular and place during use arbitrarily angledly all can be used, and positioning time is short, and in the 1s, the precision height is usually in the 1mm usually.
