A laser range finder, detect fast, detect that the precision is high, output optional (actual range value or switching value), the interference of anti sunshine as a result, distance measurement scope are adjustable, module data output mode can be wired and wireless etc. Technological advantage.
Description
Technical field
The utility model is related to technical field of measuring equipment, and in particular to a kind of laser range finder.
Background technology
Laser range finder, is that the instrument to the range measurement of target is realized using certain parameter for modulating laser.According to survey
It is divided into ranging phase method instrument and impulse method rangefinder away from method, pulse type laser rangefinder is operationally a branch of to target injection
Or the of short duration pulse laser beam of sequence, the laser beam that target reflects is received by photoelectric cell, timer determines laser beam from hair
The time of reception is mapped to, is calculated from observer's range-to-go.
Laser measuring apparatus is because the monochromaticjty of laser is good, high directivity the features such as, add electronic circuit semiconductor transformation integrated
Change, compared with geodimeter, not only day and night operation but also can improve range accuracy, substantially reduce weight and power consumption.
But, existing laser range finder, due to being limited to ligh-ranging sensor, its reaction speed is slow, be more expensive to manufacture,
It is higher to detection environmental quality requirement, it is applied to industrial detection environment more, it is higher to detection environmental quality requirement, it is not suitable for dew
Apply within it 24 hours.
Utility model content
The purpose of this utility model is the defect and deficiency for prior art, there is provided a kind of simple structure, design is closed
Reason, laser range finder easy to use, it have measuring speed fast, low cost, adapt to complicated working environment, can be in outdoor ring
The advantage of round-the-clock normal work under border.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of laser range finder described in the utility model, it includes：Semiconductor laser；Reflect the semiconductor laser
Device launches the first eyeglass of laser；Refraction is by the second eyeglass of range finding object reflected light；Receive and process the CCD of the reflected light
Array；And, the signal processor processed the ccd array signal.
Further, the ccd array is linear CCD array.
Further, the signal processor is one of simulation or digital signal processor.
Further, the ccd array outer surface is additionally provided with optical filter.
Further, the semiconductor laser is the laser for launching black light.
After said structure, the utility model has the beneficial effect that：A kind of laser range finder described in the utility model, inspection
Degree of testing the speed is fast, accuracy of detection is high, output result is optional（Actual distance value or switching value）, anti-sunlight interference, distance measurement ranges
Adjustable, the module data way of output can be wired and wireless etc. technological merit.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Description of reference numerals：
1st, semiconductor laser；2nd, the first eyeglass；3rd, the second eyeglass；4th, ccd array；5th, digital signal processor；6th, filter
Mating plate.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of laser range finder described in the utility model, including：Semiconductor laser 1, refraction are described
First eyeglass 2, the refraction of semiconductor laser laser are by the second eyeglass 3 of range finding object reflected light, reception and treatment institute
The ccd array 4 for stating reflected light, the digital signal processor 5 processed the ccd array signal.
Further, the surface of the ccd array 4 is additionally provided with optical filter 6；The ccd array 4 is linear CCD array.
Semiconductor laser 1 passes through the first eyeglass 2 by non-visible laser directive body surface a, through the laser that object a reflects
By the second eyeglass 3, received by the linear camera of the inside of ccd array 4, according to different distances, the inside of ccd array 4
Linear camera " can see " this luminous point under a different angle.Laser reflects to form angle twice, is according to this angle
The distance between semiconductor laser 1 and camera can be calculated by digital signal processor 5.
Meanwhile, light beam is processed in the position of receiving element by analogy and digital circuit, and by microprocessor analysis, meter
Calculate corresponding output valve, and in the analog quantity window of user's setting, in proportion outputting standard data-signal.If using opening
Pass amount output, then turn in the window of setting, ends outside window.In addition, analog quantity is settable with output switch parameter independent
Detection window.Therefore, a kind of laser range finder of the present utility model, it has, and detection speed is fast, accuracy of detection is high, output result
It is optional（Actual distance value or switching value）, anti-sunlight interference, distance measurement ranges are adjustable, the module data way of output can be wired
Technological merit is waited with wireless.
The above is only better embodiment of the present utility model, therefore all according to described in the utility model patent claim
Construction, the equivalent change or modification done of feature and principle, be included in the utility model patent claim.
