Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.
Fig. 1 is the synoptic diagram that the laser range finder of first embodiment of the present utility model is in distance measurement mode.Laser range finder comprises housing 101, exit lens 102, receiver lens 103, display module 104, key-press module 105, laser module and circuit control module, and is wherein not shown among laser module and circuit control module Fig. 1.After the laser beam that the laser module sends is sent from exit lens 102, drop on the object and through object and reflect, laser beam after the emission is back by avalanche photodide (Avalanche Photo Diode via receiver lens 103, APD) receive, APD inputs to the circuit control module after light signal is converted into electric signal, and the circuit control module draws the distance that measures according to described electric signal and the most original laser signal.
As shown in Figure 1, double mode laser range finder comprises that also a light changes element 106, be arranged at a side of the beam projecting of exit lens 102, in the present embodiment, light changes element 106 and is arranged in the housing 101, and double mode laser range finder also comprises an executive component 107, connects light and changes element 106.Described executive component 107 can slide in the chute 108 of housing 101.During original state, when executive component 107 is positioned at the rightmost of chute 108, light changes element 106 not on emitting light path, double mode laser range finder is under the distance measurement mode, at this moment, the light path of double mode laser range finder as shown in Figure 2, namely this moment, double mode laser range finder was exactly common laser range finder, the circuit control module can calculate the distance of object relative measurement benchmark according to emergent ray and the reflection ray that receives.
Further, wherein said light changes that element is dismountable to be installed on described casing.
Fig. 3 is the synoptic diagram that the double mode laser range finder of first embodiment of the present utility model is in the graticule pattern.At this moment, when executive component 107 was positioned at the Far Left of chute 108, light change element 106 was positioned at exit lens the place ahead and is positioned on the outgoing path of light, and the direction that light changes 106 pairs of light of element changes.In the present embodiment, it is scattering cylindrical lens that light changes element 106, and the optical axis of scattering cylindrical lens is vertical substantially with the path of beam projecting, and at this moment, double mode laser range finder is in the graticule pattern.Its light path as shown in Figure 4, because the scattering cylindrical lens is positioned on the path of beam projecting, and the optical axis L of scattering cylindrical lens is vertical substantially with the path of beam projecting, therefore the scattering cylindrical lens is converted to a laser sector with the laser beam that receives, and the optical axis L approximate vertical of this laser sector and scattering cylindrical lens.
