Qhov sib txawv ntawm infrared range finder thiab laser range finder
Muaj ob hom laser ntau yam:
1) Lub teeb liab laser ntau yam (tseem hu ua lub teeb pom kev sib txawv).
2) Infrared laser ntau yam.
Ob qho tib si tau sau npe hu ua laser range.
Muaj lwm tus ultrasonic range finder nyob rau hauv kev ua lag luam, uas yog feem ntau ua txuj ua ib tug infrared range finder los yog ib tug laser range finder los ntawm cov neeg muag khoom. Ceevfaj tsis txhob dag.
Cov txheej txheem kom paub qhov txawv laser range finder los ntawm ultrasonic range finder yog:
Laser range finders (txawm yog lub teeb liab lossis lub teeb infrared) muaj tsawg kawg yog ib lub lens optical, thiab qee qhov muaj ob lub qhov muag pom, ib qho loj thiab ib qho me me.
Ultrasonic range finder tsis muaj lub lens optical, tab sis muaj piezoelectric ceramic piece.
