Qhov chaw ntawm Ranging yuam kev hauv Optical Range Finders
Kev ntsuas qhov ntsuas qhov deb ntawm qhov ntsuas qhov ntsuas qhov yuam kev yog muab faib ua ob ntu.
(1) Qhov yuam kev loj: qhov yuam kev proportional rau qhov ntev ntawm qhov ntsuas qhov deb, feem ntau yog qhov yuam kev zaus, atmospheric refractive index yuam kev thiab lub tshuab nqus tsev ceev ntawm lub teeb kev txiav txim siab yuam kev mus rau qhov sib txawv ntawm qhov yuam kev. Ntawm lawv, qhov ceev ntawm lub teeb kev txiav txim siab yuam kev ntawm cov nqi sib txawv ntawm qhov cuam tshuam yog negligible.
(2) Kho qhov yuam kev: qhov yuam kev ntawm qhov ntsuas, uas tsis muaj dab tsi cuam tshuam nrog qhov ntev ntawm qhov ntsuas qhov deb, suav nrog kev kuaj xyuas qhov yuam kev ntawm xoom point yuam kev, qhov yuam kev hauv nruab nrab ntawm lub ntsuas ntsuas thiab qhov cuam tshuam, qhov ntsuas theem yuam kev , lub amplitude theem yuam kev, lub luminous raj theem inhomogeneity yuam kev thiab lub voj voog yuam kev. Cyclic yuam kev feem ntau yog los ntawm cov cuab yeej hauv optoelectronic teeb liab ntawm tib zaus scrambling, qhov loj ntawm qhov yuam kev yog rov ua dua lub voj voog ntawm qhov ntev ntawm daim kab xev ntsuas zoo.
Ntawm lawv, qhov kev faib ua feem yuam kev, lub voj voog yuam kev, xoom yuam kev rau lub ntsiab lus yuam kev ntawm photoelectric rangefinder.
Raws li ib tug loj tus naj npawb ntawm ntsuas cov ntaub ntawv qhia tau hais tias: vim lub teeb-emitting thiab txais tube theem inhomogeneity thiab amplitude theem yuam kev thiab lwm yam, lub ntsuas kuj muaj nyob rau hauv tas li ntawd mus rau lub zaus yuam kev thiab atmospheric refractive index yuam kev, thiab ntev. ntawm qhov kev ncua deb cuam tshuam nrog lub sij hawm kho, customarily yuav cuam tshuam nrog qhov kev ncua deb cuam tshuam txog qhov ntev ntawm tus naj npawb ntawm kev kho sib sau ua ke hu ua qhov sib npaug tas li! Kev kho ntawm xoom yuam kev yog hu ua ntxiv rau qhov tsis tu ncua. Kev ua yuam kev tuaj yeem tau txais los ntawm kev ntsuas qhov systematic yuam kev tus nqi thiab qhov kev txiav txim ntawm kev kho kom tshem tawm txoj kev. Yog li ntawd, kev txheeb xyuas qhov kev ua yuam kev ntawm lub photoelectric rangefinder feem ntau suav nrog peb yam hauv qab no.
(1) periodic yuam kev calibration.
(2) Ntxiv qhov tsis tu ncua ntawm calibration.
(3) multiplication tas mus li calibration.
