Ganda rakajairika rinokwanisa kutora chiedza kuchengetedza nhengo uye matishu ari mumuviri kubva mukukuvadzwa kwechiedza.Kugona kwechiedza kupinda munyama yemunhu kunoenderana zvakanyanya nehurefu hwayo uye chimiro cheganda reganda.Kazhinji, kupfupika kwewavelength, kusadzika kwekupinda mukati meganda.Mucheka weganda unotora chiedza nekusarudza kuri pachena.Semuenzaniso, keratinocytes mu stratum corneum inogona kutora yakawanda yenguva pfupi-wave ultraviolet rays (wavelength is 180 ~ 280nm), uye masero e spinous ari mu spinous layer uye melanocytes mu basal layer inotora nguva yakareba-wave ultraviolet rays. wavelength ndeye 320 nm ~ 400nm).Iyo ganda reganda rinotora akasiyana mafungu echiedza zvakasiyana, uye mazhinji emiranzi yeultraviolet inotorwa ne epidermis.Sezvo wavelength inowedzera, chiyero chekupinda kwechiedza chinoshandukawo.Mwaranzi ye infrared padyo nemuchina wemwenje tsvuku inopinda mukati memukati meganda, asi inotorwa neganda.Iyo yakareba-wave infrared (wavelength ndeye 15 ~ 400μm) inopinda zvisina kunaka, uye yakawanda yacho inotorwa ne epidermis.
Izvo zviri pamusoro apa ndiyo nheyo yedzidziso iyo iyoganda analyzerinogona kushandiswa kuona yakadzika ganda pigmentation matambudziko.Theganda analyzerinoshandisa akasiyana spectra (RGB, Cross-polarized light, Parallel-polarized light, UV mwenje uye Wood's mwenje) kugadzira akasiyana wavelengths kutsvaga matambudziko eganda kubva kumusoro kusvika kune yakadzika layer, saka wrinkles, spider veins, pores hombe, nzvimbo dzepamusoro, mavara akadzika, pigmentation, pigmentation, kuzvimba, porphyrins uye mamwe matambudziko eganda anogona kuwonekwa neanoongorora ganda.
