State division light prism group 20, a display module 95, a detector 99 and an eyepiece 97.Optical transmitting system 92 has one second thing
Mirror 98 and a transmitting knob part 96.The image strip that object produces visible wavelength range injects the survey of this optics from the first object lens 94
Away from device 90；Then it is seen that the image light of optical wavelength range injects division light prism group from the first light output/input face 213
20.In this division light prism group 20, image strip is advanced along the path of above-mentioned first wave length light beam rl, and defeated from the second light
Go out/input face 223 is from liter.Afterwards, image strip passes through eyepiece 97, makes observer can clearly watch object.Emitting module
96 have a laser diode 961 and a lens knob 962, and launch an infrared wavelength light beam.This infrared wavelength light beam passes through the
Two object lens 98, advance towards object.This infrared wavelength is reflected by object；Wherein, the part infrared wavelength light beam of reflection leads to
Cross the first object lens 94, inject observation/receiving optics 91 in observation/receiving optics 91, infrared wavelength light beam is certainly
First light output of roof prism 21/input face 213 injects this division light prism group 20；Then, this infrared wavelength light beam edge
Advance in the path above-mentioned second wave length light beam r3, and the four light outputs/input face 232 of self compensation prism 23 is from liter.Finally,
Detector 99 receives infrared wavelength light beam.Therefore, optical distance measurement apparatus 90 come and go object and range finding according to infrared wavelength light beam
The distance between flight time between device, calculating optical range unit and object.Display knob part 95, such as liquid crystal display
Assembly, LED numerical monitor assembly, the set narrow wavelength light end of transmitting, and show the distance measuring.Display module 95 is launched
Specific wavelength light be derived from compensator 23 the second light output/input face 231 inject division light prism group 20.This narrow wavelength
Light beam along the path bank address of above-mentioned second wave length light beam r2, and from the second light output/input face 223 from liter.Afterwards, narrow wavelength
Light beam passes through eyepiece 97 so that observer can clearly watch the numeral that display module shows.
To sum up, in existing technology, the compensating glass 23 that this optical distance measurement apparatus discloses, is First Five-Year Plan angle mirror, structure is multiple
Miscellaneous, cost of manufacture is high, and the wavelength light beam that infrared wavelength is launched with light beam display module 95.Because of structural relation, the thang-kng of two light
Aperture is limited.
