ROF -BPR mndandanda wa module yowunikira yowunikira bwino (yolinganiza chithunzithunzi cha Silicon Photodetector) imagwirizanitsa ma photodiode awiri ofanana ndi amplifier otsika kwambiri a phokoso, kuchepetsa phokoso la laser ndi phokoso lodziwika bwino, kupititsa patsogolo phokoso la dongosolo, kukhala ndi mayankho osiyanasiyana. kusankha, Phokoso laling'ono, kupindula kwakukulu, kosavuta kugwiritsa ntchito ndi zina zotero, Zogwiritsidwa ntchito makamaka powonera, kuzindikira kwa heterodyne, kuyeza kuchedwa kwa kuwala, kuwala kogwirizana ndi tomography ndi zina.
Module yodziwikiratu yodziwika bwino (Balanced Photodetector) yokometsedwa pamakina amtundu wachitatu wa OCT (SS-OCT), wokhala ndi kupindula kwakukulu komanso mawonekedwe aphokoso otsika, kukana kwamitundu yodziwika bwino kudzera kukhathamiritsa kwa kutalika kwa mafunde, kutulutsa mphamvu kwamagetsi (~ 7V), ndikusintha chizindikiro chowunikira cha Monitor (mpaka 10Vpp). Chowunikirachi chikupezeka pa DC-400MHz, 500K-1GHz, 500K-1.6GHz ndipo chimakongoletsedwa ndi 1064nm ndi 1310nm mafunde.
