Lub hauv paus ntawm kev ua yuam kev ntawm photoelectric rangefinder
Qhov kev ua yuam kev ntawm photoelectric rangefinder tau muab faib ua ob ntu:
(1) Qhov yuam kev loj: qhov yuam kev proportional rau qhov ntsuas qhov ntev yog feem ntau tshwm sim los ntawm qhov yuam kev zaus, atmospheric refractive index yuam kev thiab lub tshuab nqus tsev lub teeb nrawm ntsuas qhov yuam kev. Ntawm lawv, qhov cuam tshuam ntawm qhov yuam kev ntawm kev ntsuas lub teeb nrawm ntawm tus nqi sib txawv tuaj yeem tsis quav ntsej.
(2) Kho qhov yuam kev: qhov yuam kev ntawm qhov ntsuas tsis muaj dab tsi cuam tshuam nrog qhov ntsuas qhov ntev, suav nrog kev ntsuas qhov yuam kev ntawm xoom yuam kev, kev sib dhos yuam kev ntawm qhov ntsuas thiab qhov cuam tshuam, qhov ntsuas theem yuam kev, amplitude-phase yuam kev , cov theem tsis sib xws ntawm LED thiab lub sij hawm yuam kev. Qhov yuam kev tsis tu ncua feem ntau yog los ntawm tib zaus cuam tshuam ntawm cov teeb liab photoelectric hauv qhov ntsuas, thiab qhov loj ntawm qhov yuam kev rov ua dua nrog qhov ntev ntawm tus kav precision raws li lub voj voog.
Ntawm lawv, proportional yuam kev, lub sij hawm yuam kev thiab xoom yuam kev yog lub ntsiab system yuam kev ntawm photoelectric rangefinder.
Raws li ib tug loj tus naj npawb ntawm cov ntaub ntawv ntsuas, nws yog pom tau hais tias vim lub theem inhomogeneity ntawm lub teeb-emitting raj thiab lub txais lub raj ntawm lub ntsuas, amplitude thiab theem tsis ua hauj lwm thiab lwm yam, lub ntsuas tseem muaj kev kho cov nqe lus hais txog qhov ntev. ntawm qhov deb dua li qhov yuam kev zaus thiab atmospheric refractive index yuam kev. Kev lig kev cai, cov lej kho uas cuam tshuam nrog qhov ntev ntawm qhov kev ncua deb hu ua qhov sib npaug sib npaug! . Kev kho tus naj npawb ntawm xoom yuam kev yog hu ua ntxiv qhov tsis tu ncua. Qhov kev ua yuam kev tuaj yeem raug tshem tawm los ntawm kev tau txais qhov system yuam kev hauv kev txheeb xyuas thiab siv kev kho. Yog li, kev txheeb xyuas qhov yuam kev ntawm lub tshuab photoelectric rangefinder feem ntau suav nrog peb yam hauv qab no:
(1) kev txheeb xyuas qhov yuam kev tsis tu ncua;
(2) Kev txheeb xyuas ntawm kev ntxiv qhov tsis tu ncua;
(3) Kev txheeb xyuas qhov sib npaug tas li.
