Embodiment
Followingly the utility model is described in detail with reference to drawings and Examples.
Fig. 1 is the structural representation of the vertical device of photoelectricity of the present utility model.As shown in Figure 1, the vertical device of photoelectricity of the present utility model comprises the glass tube 1 of closed at both ends, is fixedly connected on the LASER Discharge Tube 2 of glass tube 1 one ends, is connected the surface array charge-coupled device 4 and the middle plummet 3 that is provided with vertical perforation of glass tube 1 other end.It is interior also fixing that the tail optical fiber end of LASER Discharge Tube 2 penetrates the vertical perforation of plummet 3, is connected with data-out port 5 on the surface array charge-coupled device 4.
Described glass tube 1 is the right cylinder of 20mm for diameter.LASER Discharge Tube 2 is the LASER Discharge Tube of the single-mode tail fiber of 9um for diameter, the laser beam of emission wavelength 650nm.Photosensitive long 25um, high 2.5nm, the 1024 pixel length overall 25.6mm of being of a size of of effective photodiode of surface array charge-coupled device 4.Obviously, the area of its photosurface is bigger, is 6.25*104(um
2), corresponding illumination sensitivity height.
During this device work, diameter is the laser of the LASER Discharge Tube 2 emissions one beam diameter 9um wavelength 650nm of 9um, surface array charge-coupled device 4 receives the 650nm laser of this bundle 9um, according to the laser beam difference that receives at diverse location, can accurately judge vertical position data, the sensing element distance of surface array charge-coupled in addition device 4 is 25um only, so can analyze vertical side-play amount, its scale division value is 25um.
The circuit output that its vertical side-play amount numerical value links to each other with surface array charge-coupled device data-out port 5 by surface array charge-coupled device 4.
The vertical device of photoelectricity of the present utility model adopts laser beam to measure, and analyzes vertical side-play amount, the accuracy height; Can be embedded in other surveying instrument and use, as the usefulness of the adjustment of the initial value of the debugging of online comprehensive instrument and instrument, applied widely; And processing and easy to use.
