Usoro ojiji nke usoro R-QCD300 nke ihe nchọpụta silikọn na-agba ọsọ n'efu gụnyere: lidar otu-photon, nchọpụta ndụ fluorescence, onyonyo otu-photon, nkwukọrịta quantum, optics quantum, ntụgharị uche mpaghara optical, wdg. E gosipụtara ngwa ndị a na-ejikarị eme ihe na eserese a.

N'ime ngwa dịka lidar nke otu photon na onyonyo otu photon, a na-ewepụta ìhè laser pulsed site na laser gaa na ihe mgbaru ọsọ ahụ. Foton mgbaàmà ahụ na-agbasa ma ọ bụ na-egosipụta mgbe ha zutere molekul n'ikuku ma ọ bụ ihe mgbaru ọsọ siri ike. Mgbe a chịkọtara ha n'ebe a na-ewepụta laser, a na-anakọta akara echo photon nke a na-egosipụta ma ọ bụ nke a na-agbasa. A na-achọpụta akara ndị a site na iji ihe nchọpụta otu photon, a na-enyochakwa akara nchọpụta ahụ na njikọ ya na akara mwepụ laser site na iji ihe mgbanwe dijitalụ oge iji nweta oge ụgbọ elu photon. N'ikpeazụ, a na-agbakọ anya nke ihe ebumnuche site na iji ọsọ nke ìhè. Na ngwa lidar nke ikuku, a na-achọpụta laser azụ gbasasịrị site na ikuku iji nweta ozi anụ ahụ nke ikuku. Na ngwa lidar onyonyo atọ, a na-enweta ozi anya nke pikselụ ọ bụla site na nyocha, mgbe ahụ a na-emegharị onyonyo atọ nke ihe ebumnuche achọpụtara nke ọma site na iji algọridim onyonyo. N'ihi mmekọrịta square dị n'etiti ike nke akara echo nke lidar natara na anya nchọpụta, ka anya nchọpụta na-abawanye, ike mgbaàmà ga-ebelata nke ukwuu. Ọzọkwa, n'ihi na ikuku na-agbasasị ma na-amịkọrọ laser ahụ n'oge njem gburugburu ya, ike mgbaama ga-ebelata. Ma e jiri ya tụnyere ihe nchọpụta fotoelectric ọdịnala, ihe nchọpụta otu-photon nwere mmetụta dị elu ma nwee ike ịzaghachi akara foton nke ọ bụla, na-eme ka nchọpụta anya dị anya ma belata ịdabere na ike mwepụ laser.
