Rofea e ikemetse e ntlafalitse photodetector e kopantseng photodiode le potoloho ea amplifier ea lerata le tlaase, ha e ntse e fana ka lihlahisoa tse fapa-fapaneng, bakeng sa basebelisi ba lipatlisiso tsa saense Fana ka tšebeletso ea boleng ba lihlahisoa, tšehetso ea botekgeniki le tšebeletso e bonolo ka mor'a thekiso. Mohala oa hona joale oa sehlahisoa o kenyelletsa: sesebelisoa sa setšoantšo sa analog se nang le amplification, fumana photodetector e feto-fetohang, photodetector ea lebelo le phahameng, High Speed InGaAs Photodetector, mochine oa 'maraka oa lehloa (APD), mochine oa ho leka-lekanya, Photodetector e tlaase ea Noise, Photoreceiver ea Low Noise PIN, joalo-joalo.
