ROF -BPR letoto la module ea ho lemoha leseli le leka-lekaneng (photodetector e leka-lekaneng) e kopanya li-photodiode tse peli tse ts'oanang le amplifier ea Ultra-low lerata ea transimpedance, ka katleho e fokotsang lerata la laser le lerata le tloaelehileng la mokhoa, ho ntlafatsa tekanyo ea lerata ea tsamaiso, ho ba le mefuta e fapaneng ea karabelo ea spectral, Lerata le tlase, phaello e phahameng, e bonolo ho e sebelisa joalo-joalo, E sebelisoa haholo bakeng sa spectroscopy, ho lemoha heterodyne, optical delay measurement, optical coherence tomography le likarolo tse ling.
Mojule oa ho lemoha o leka-lekaneng o ntlafalitsoeng bakeng sa lits'ebetso tsa OCT ho ophthalmology o na le phaello e phahameng le litšobotsi tse tlase tsa lerata, tekanyo e phahameng ea ho hana mokhoa o tloaelehileng le amplitude e phahameng ea voltage (~ 12V) ka ntlafatso ea maqhubu. E kile ea sebelisoa lits'ebetsong tsa batch lisebelisoa tsa bongaka tsa OCT, 'me sesebelisoa se ka boela sa ntlafatsoa bakeng sa 1310nm le 1550nm wavelengths.
