Imashini ishyirwa hejuru y'icyuma gishyushya, kandi icyuma gishyushya gikoresheje ikoranabuhanga cyohereza icyuma gishyushya hejuru y'ibikoresho bigenzurwa. Aho ngaho, bigaruka inyuma kandi bikakirwa na pro be. Imashini ipima igihe t hagati yo kohereza pulse no kwakira. Imashini ikoresha igihe t (n'umuvuduko w'ijwi c) kugira ngo ibare intera d hagati y'igice cyo hasi cya sensor n'ubuso bw'amazi bugenzurwa: d = c •t/2. Kubera ko imashini izi uburebure bwa H bwo gushyiraho uhereye ku bipimo, ishobora kubara urwego rukurikira: h = H – d.
Kubera ko umuvuduko w'amajwi mu kirere uterwa n'impinduka mu bushyuhe, OCM yashyizemo uburyo bwo gupima ubushyuhe kugira ngo inoze uburyo bwo gukoresha neza amajwi.
Ku bijyanye n'amatara yagenwe, hari isano idahinduka hagati y'amazi asohoka ako kanya n'amazi asohoka. Ifishi ni Q=h (x). Q bivuze amazi asohoka ako kanya, h bivuze amazi asohoka ako kanya muri amatara. Bityo, igikoresho gishobora kubara umuvuduko w'amazi binyuze muri amatara yagenwe n'agaciro k'amazi.
Ni ingenzi cyane gusobanukirwa ihame ry'imikorere kugira ngo habeho gukomeza gushyirwaho no gukoreshwa.
