Uruhu rusanzwe rufite ubushobozi bwo kwinjiza urumuri kugira ngo rurinde ingingo n'imitsi mu mubiri kwangirika k'urumuri. Ubushobozi bw'urumuri bwo kwinjira mu ngirabuzimafatizo z'umuntu bufitanye isano rya bugufi n'uburebure bw'urumuri rwarwo n'imiterere y'imitsi y'uruhu. Muri rusange, uko uburebure bw'urumuri buba bugufi, niko ruhu rwinjira buhoro buhoro. Imitsi y'uruhu ifata urumuri ku buryo bugaragara. Urugero, keratinocytes muri stratum corneum ishobora kwinjiza imirasire myinshi ya ultraviolet y'amawave magufi (uburebure bw'urumuri ni 180 ~ 280nm), naho uturemangingo tw'imigongo mu gice cy'umugongo n'uturemangingo tw'umugongo mu gice cy'ibanze bitwara imirasire ya ultraviolet y'amawave maremare (uburebure bw'urumuri ni 320 nm ~ 400nm). Imitsi y'uruhu ifata uburebure butandukanye bw'urumuri mu buryo butandukanye, kandi imirasire myinshi ya ultraviolet ifatwa n'uruhu. Uko uburebure bw'urumuri bwiyongera, urwego rw'urumuri narwo rurahinduka. Imirasire ya infrared hafi y'imashini y'urumuri rutukura yinjira mu bice byimbitse by'uruhu, ariko itwarwa n'uruhu. Infrarouge y'urumuri rurerure (uburebure bw'urumuri ni 15 ~ 400μm) yinjira nabi cyane, kandi igice kinini cyayo cyinjizwa n'urumuri rw'inyuma.
Ibi byavuzwe haruguru ni ishingiro ry'inyigisho z'ukoisesengura ry'uruhuishobora gukoreshwa mu gupima ibibazo by'uruhu rwinshi.isesengura ry'uruhuikoresha spectra zitandukanye (RGB, Cross-polarized light, Parallel-polarized light, UV light na Wood's light) kugira ngo ikore uburebure butandukanye bw'uburebure kugira ngo imenye ibibazo by'uruhu kuva ku buso kugera ku buso bunini, bityo iminkanyari, imitsi y'igitagangurirwa, imyenge minini, ibibara byo hejuru, ibibara byimbitse, ibara, ibara, ububyimbirwe, porphyrins n'ibindi bibazo by'uruhu byose bishobora kugaragazwa n'umusesenguzi w'uruhu.
