Embodiment
Referring to Fig. 1, hand-held laser rangefinder measuring system is (0.5+1 * 10 by distance accuracy
-6d) electronic total station 1 of mm, optical path changing system 2, guide rail 3, hand-held laser rangefinder clamping and positioning device 4, electronic total station clamping and positioning device 5 form.Optical path changing system 2 is comprised of near-end catoptrics assembly 21 and the far-end catoptrics assembly 22 that can move along guide rail 3, on near-end catoptrics assembly 21, place the second catoptron group 6, the first diaphragm 7, reflecting plate 8, far-end catoptrics assembly 22 is placed the first catoptron group 9, the 3rd catoptron group 10, the second diaphragm 11.
By the optical transition system being formed by near-end catoptrics assembly 21 and far-end catoptrics assembly 22, the straight line light path of 15 meters long is passed through to 6 secondary reflections, be converted to 50 meters of long light paths, adjust hand-held laser rangefinder its light path is overlapped with the light path of electronic total station 1,1 the photometry journey of electronic total station of take is standard value D

Hand-held laser rangefinder clamping and positioning device can complete the angular setting of X, the translation of Z direction, pitching, beat direction.Z axis moving range 60mm, X-axis moving range 20mm, 4 ° of horizontal direction beat scopes, 4 ° of angle of pitch setting ranges, referring to Fig. 2.
Because electronic total station itself is with horizontal dial and vertical circle, self possesses the adjustment function of deflection angle and the angle of pitch, so electronic total station clamping and positioning device only designs the displacement function of X, Y, Z three-dimensional.X-axis setting range 100mm, Y-axis setting range 100mm, Z axis setting range 500mm, referring to Fig. 3.
Guide rail total length is 16 meters, is to be spliced into two parallel guide rails by 32 1 meter of long steel pipes, and guide rail linearity is 2mm.In testing process, due to what adopt, be the light path of main measurement standard electronic total station and the method that hand-held laser rangefinder light path coincides, so guide rail linearity only exerts an influence to spot displacement, on not directly impact of test result.
Hand-held laser rangefinder emergent light is parallel with guide rail 3, and guarantee is at far-end catoptrics assembly 22 along in guide rail 3 moving process, and the facula position that the hand-held laser rangefinder emergent light of process multiple reflections projects on reflecting plate 8 remains unchanged.Method of adjustment is as follows:
1) as shown in Figure 1, along guide rail 3, move far-end catoptrics assembly 22 near near-end catoptrics assembly 21, high and low position and the horizontal level of adjusting hand-held laser rangefinder make its light path by the center of the first diaphragm 7, adjust the center superposition of the first diaphragm 7 and the second diaphragm 11 simultaneously, make hand-held laser rangefinder light path simultaneously also by the second diaphragm 11 center.
2) mobile far-end catoptrics assembly 22, apart from the about 12 meters of left and right of near-end catoptrics assembly 21, is adjusted the angle of pitch and the deflection angle of hand-held laser rangefinder, makes its light path by the second diaphragm 11 center.
3) along guide rail 3, move far-end catoptrics assembly 22 near near-end catoptrics assembly 21, whether observe hand-held laser rangefinder emergent light overlaps with the first diaphragm 7 and the second diaphragm 11 center, as change, repeat above-mentioned adjustment, until hand-held laser rangefinder emergent light can pass through the first diaphragm 7 and the second diaphragm 11 centers at far-end catoptrics assembly 22 when the most nearby with in farthest, prove that hand-held laser rangefinder emergent light and guide rail 3 are in parastate.
Equally, electronic total station emergent light and guide rail parallel, guarantee is at far-end catoptrics assembly along in guide rail moving process, and the facula position that the electronic total station emergent light of process multiple reflections projects on reflecting plate remains unchanged.Electronic total station emergent light is identical with the method for adjustment of hand-held laser rangefinder emergent light and guide rail parallelism with the adjustment of guide rail parallelism.
In optical path changing system 2, plane mirror forms respectively prism square in the mode of a group between two, used altogether three groups of plane mirrors, the first catoptron group 9 and the 3rd catoptron group 10 are placed on far-end catoptrics assembly, and the second catoptron group 6 is placed on near-end catoptrics assembly.
In hand-held laser rangefinder measuring system, plane mirror be take the mode of a group between two and is formed respectively the prism square that angle is 90 °, and the advantage of prism square is that reflected light and incident light are completely parallel in principle.Therefore, plane mirror can not be strict placing with hand-held laser rangefinder light path angle at 45 °, as long as guarantee that the angle of two sides plane mirror is 90 °, just can guarantee the collimation of light.
When respectively organizing the adjustment of plane mirror angle, mobile far-end catoptrics assembly makes 15 meters of the spacing of the first diaphragm 7 and the second diaphragm 11, near the first diaphragm 7 and the second diaphragm 11, use the glass linear standards of light-permeable to measure respectively D1 and D2, adjust the deflection angle of the first plane mirror group 9, making D1=D2 is that incident light is parallel with reflected light, and the angle that can guarantee two sides level crossing is 90 °.With same method, adjust plane mirror group 2 and flat mirror reflects group 3 angle in 90 °.
