Description

Laser projected scale system
Technical field
The present invention relates to a kind of scale, be specifically related to a kind of laser projected scale system.
Background technology
At present, a kind of prior art, the laser radiation of launching from lasing light emitter is in the transmission-type scale.By moving of transmission-type scale, the polarization angle of transmitted light changes according to the orientation of the 1/2 wavelength sheet of arranging along longitudinally.Polarization angle does not allow to be subject to the influence of noise factor such as ambient light.Because analyzer is crossed in transmission and lean on the light intensity of the polarized component that photodetector detected to change according to polarization angle, so change along with moving of transmission-type scale, detection signal is exported to the amount of movement arithmetic unit.If come the computing amount of movement, then can detect amount of movement accurately based on this signal.
Another kind of prior art, laser projector, only just can on the omnirange in the predetermined planes such as surface level, throw continuous light in a narrow margin simultaneously with a light source, and before product export, adjust easily, optical system by fixed cylinder glass and by the somascope portion of axle supporting light sources supporting mass, from the upwardly extending support of somascope portion, and 2 foot sections of extending downwards constitute.Can in surface level, carry out the position adjustment to discoideus reflecting body on the top of support.The parallel rays generating apparatus that is made of light source and lens is installed on the light source placing plate, can be in the enterprising line position adjustment of this light source placing plate.
Also has a kind of prior art, remote measurement laser scale, relate to the design and fabrication technology of measuring apparatus, send equality beam laser transmitter by two and constitute, generating laser is dress optically focused convex lens and a laser diode in being provided with the fixed cover of laser emission port, is fixedly set in the firm banking, firm banking is provided with the positioning screw, the fixed cover afterbody is a spring, and the spring other end leans on the firm banking bonnet, and there are laser emission port and fixed orifice in the firm banking front portion.Two groups of laser send parallel beam, two groups of luminous points are shot with video-corder into, thereby the size of definite testee are used for bottom culture, sea floor exploration, industries such as the observation of forest animal.
The shortcoming of the remote measurement laser scale of this prior art is:
1, the remote measurement laser scale of this prior art uses in the time of can not being used for the light amplification projection owing to be not provided with projection arrangement, and usable range is narrow.
2, the remote measurement laser scale of this prior art is owing to be provided with two parallel generating lasers, the cost height, and complex structure can not be applied to teaching classroom, and experimental phenomena is simple and clear inadequately.
Summary of the invention
The purpose of this invention is to provide a kind of laser projected scale system, the measuring system that can utilize laser projections light source and catoptron to form can be distinguished the reading of measuring voltage by nonadjustable signal and movable scale, so that the student demonstrates observation.
The purpose of laser projected scale system of the present invention is achieved through the following technical solutions: a kind of laser projected scale system comprises housing, is arranged on the projection source of the back upper place of case top; Also comprise catoptron, scale and moving element.
Described moving element is arranged in the housing.
Described moving element is made of moving-coil and the pointer that is arranged on the moving-coil.
Described scale is arranged on the housing front.
Described catoptron is installed in the moving-coil top.
Described catoptron is arranged on the top of back side of shell.
Described catoptron is 0.3 square centimeter of super-thin high efficient level crossing.
Described scale also comprises movable scale, is arranged on blackboard or the wall survey measurements.
Described moving-coil is made of aluminium frame and the coil winding that is wound on the aluminium frame.
Described coil winding is that diameter is the copper enameled wire of 1-1.5mm.
Above-mentioned laser projected scale system, wherein, the moving-coil pointer is connected with catoptron, when pointer deflects, the drive catoptron rotates, and projection source is opened and is radiated on the catoptron, by reflected illumination on blackboard or wall, and on blackboard or wall calibrate, can survey measurements or can directly read by the nonadjustable signal that is arranged on housing of the present invention dead ahead.
Laser projected scale system of the present invention makes it compared with prior art owing to adopted above-mentioned technical scheme, has following advantage and good effect:
1, laser projected scale system of the present invention is owing to be provided with the laser projections light source, and mission life can reach more than 5000 hours, and it is low to consume energy.
2, laser projected scale system of the present invention is owing to be provided with 0.3 square centimeter of super-thin high efficient level crossing as catoptron, and projection distance is far away, and the scope of application arrives hall greatly, and is little of laboratory table.
3, laser projected scale system cost of the present invention is low, simple in structure, and processing ease, the tinkling of pieces of jade are portable ingeniously, is easy to maintenance and repair and popularization and application.
