Nhanganyaya yekurapa endoscope optical system
Parizvino, endoscopes ekurapa anonyanya kusanganisira matatu marudzi: faibha yemagetsi endoscopes, yakasimba endoscopes uye capsule endoscopes. Hard endoscope inoita basa rakakosha mukuongororwa kwekurapa kwakawanda, kuongororwa uye kurapwa nekuda kwezvakanaka zvekufungidzira kwakajeka, mutengo wakaderera uye yakakwirira imaging resolution.
Kuvhiya kwakaomarara kusingapindire zvishoma kuisa endoscope yakaoma mumuviri wemunhu (semudumbu remudumbu), shandisa mwenje unotonhora unovhenekera kuburikidza neoptical fiber, uye kutumira mufananidzo kukhamera yedhijitari kuburikidza neoptical system, iyo inoratidzwa pane yakakwira{0}definition display munguva chaiyo. Ipapo chiremba anoongorora, anotonga uye anoshanda pamamiriro emurwere maererano nemufananidzo wetishu nhengo iri pakuratidzira.
Iyo yemaziso sisitimu yekurapa yakaoma endoscope inonyanya kusanganisira zvikamu zvina: yakasimba endoscope, coupling lens, splitting prism uye CMOS mufananidzo sensor. Hard endoscope inogona kukamurwa kuita chinangwa lens, relay system uye eyepiece.
Iyo chinangwa lenzi yezvokurapa yakaoma endoscope ine hunhu hupfupi hwekutarisa kureba, nzvimbo yakakura yekuona uye kureba kwemaziso. Naizvozvo, iyo optical system inowanzo gadzirwa ine inverse telephoto chinangwa lens chimiro. Iro negative power lens boka rinoshandiswa seboka repamberi, uye simba rakanaka lens boka rinoshandiswa seboka remashure. Kana danda rakafanana richiitika, rinoparadzirwa neboka rekumberi uye robva raumbwa kuita mufananidzo uri panhandare yendege. Iyo huru yepamusoro yeiyi optical system inobviswa kubva kune chinangwa lens kuenda kumashure, nekudaro kuwana chinhambwe chekushanda chakareba kupfuura kureba kwekutarisa. Pamusoro pazvo, mushure mekunge-akisi bhindamu ine kona yemunda hombe yatsaukana neboka regetsi regetsi remagetsi, divergence angle ichipinda mupositive power lens boka inova diki, kuitira kuzadzikisa chinangwa chekona yakakura.
Kuti upinde mukati memuviri wemunhu kuti utarise maronda, iyo yekurapa yakaoma endoscope inoda kugadzirwa nehurefu hwakati, senge laparoscope, iyo inowanzoita 30 cm kureba. Izvi zvinoda kuti kuwedzera kune yekufungidzira chinangwa lens, iyo endoscope yakaoma inodawo girazi retsvimbo kuti riite senge relay image transmission system, ine magnification ye - 1. Kushandiswa kwemapoka asinganzwisisiki anogona kuita kuti hurongwa huve hwakanaka.
Basa reiyo endoscope eyepiece ndeyekupfuudza mufananidzo wakaumbwa neicho chinangwa lens uye relay system kuburikidza nemeso uye kupinda muziso remunhu muchimiro chechiedza chakafanana.
Ikozvino, iyo adapta lens inowedzerwa pahwaro hweiyo endoscope yekuona, kuitira kuti mwenje unobuda weziso rigone kufananidzirwa pane CMOS chinangwa kuburikidza neadapter lens. Iyo yekubuda pupil ye eyepiece ndiyo yekupinda pupi yeadapter
Kupfupisa, maererano nedhizaini yakazara, iyo endoscope mune yese optical system inogona kuenzaniswa nechinangwa chemifananidzo. Zvichireva kudzika kwekuongororwa kwemunda mulenzi yekamera, kudzika kwemunda weiyo endoscope imaging system inotarisa pane endoscope pachayo, kwete iyo lens.
