Rofea yakazvimiririra yakagadzira photodetector yakabatanidzwa photodiode uye yakaderera ruzha amplifier wedunhu, ichipa zvakasiyana-siyana zvezvigadzirwa, zvevashandisi vetsvagiridzo yesainzi Ipa sevhisi yemhando yechigadzirwa, rutsigiro rwehunyanzvi uye nyore mushure mekutengesa sevhisi. Mutsara wechigadzirwa chazvino unosanganisira: analog chiratidzo fotodetector ine amplification, kuwana inogadzirika fotodetector, high speed photodetector, High Speed InGaAs Photodetector, snow market detector (APD), balance detector, Low Noise Photodetector, Low Noise PIN Photoreceiver, nezvimwewo.
