I-laser ye-infrared engu-1310nm/1550nm yamukela i-LD engenisiwe, enezici zokukhanya okuphezulu, imvamisa yokuguquguquka okuphezulu kanye ne-spectrum emsulwa.Ilungele ucwaningo lwesayensi, imithi, ukuxhumana nge-laser, ukukhanyisa neminye imikhakha.
Umthombo wokukhanya ulawulwa isikrini sokuthinta, esingasetha kalula imingcele efana namandla okukhiphayo, imvamisa, nomjikelezo wemisebenzi.Ngesikhathi esifanayo, ukuze kube lula ukusetshenziswa, umthombo wokukhanya uphinde unikeze isikhombimsebenzisi sokulawula sangaphandle.Amakhasimende angasebenzisa imbobo yokushintshashintsha ye-TTL ukuze avumelanise ukukhanya nokuphelelwa yisikhathi kwe-laser nesiginali yokulawula yangaphandle.Iswishi engukhiye kuphaneli yangaphambili iqinisekisa ukuthi izisebenzi ezigunyaziwe kuphela ezingafinyelela umthombo wokukhanya.
