Urukurikirane rw'ibikoresho byo gupima amashusho: Intangiriro yo gusuzuma amashusho mu buryo bwo kuringaniza

Intangiriro kuriImashini ipima foto iringaniye(Optoelectronic Balance Detector)
Imashini ipima ishusho ya Balance ishobora kugabanywamo ubwoko bw'ihuza rya fiber optic n'ubwoko bw'ihuza rya optical spatial hakurikijwe uburyo bwo guhuza optical. Imbere, igizwe na photodiode ebyiri zihuye cyane, module y'ihuza rya transimpedance amplifier circuit module ifite urusaku ruto, na module y'ihuza rya transimpedance power low noise. Ifite imiterere ya common mode rejection ratio, ultra-low noise, na bandwidth low, kandi ikoreshwa cyane mu itumanaho ry'amajwi. Yabaye ahantu hakorerwa ubushakashatsi ku bigo na za kaminuza mu bihugu bitandukanye mu myaka yashize.
Ihame ry'imikorere rya Balance Photodetector (Igipima imiterere y'amajwi n'amashusho (Optoelectronic Balance Detector))
Ishusho y'ishusho ikoresha fotodiode ebyiri ziri mu mimerere ya reverse bias nk'igice cyakira urumuri. Iyo wakiriye ikimenyetso cy'urumuri, fotodiode ebyiri zikorwa na fotodiode zirakurwamo zigahuzwa na amplifier ya transimpedance kugira ngo zihindure ikimenyetso cy'urumuri mo ikimenyetso cy'amashanyarazi kugira ngo gikoreshwe. Gukoresha imiterere yigenga bishobora gukumira neza ikimenyetso cy'uburyo busanzwe cyashyizweho n'urumuri rwa oscillator rwo mu gace n'umuriro wijimye, byongera ikimenyetso cy'uburyo bwo gutandukanya, no kunoza ubushobozi bwo kumenya ibimenyetso by'urumuri bidakomeye.
Ibyiza: Igipimo cyo kwanga uburyo busanzwe cyane, ubushobozi bwo kumenya amakuru menshi, hamwe n'uburyo bwo kubona amakuru menshi bishobora gukemura ibibazo bitandukanye byo gukoresha.
Ingaruka mbi: Ingufu nke z'urumuri rwuzuye, zikwiriye gusa mu kubona urumuri rudakomeye, guhuza bigomba kunozwa.

IGISHUSHANYO: Imbonerahamwe y'ibanze y'imikorere y'igikoresho cyo gupima uburinganire
Ibipimo by'imikorere bya Balance Photodetector (Optoelectronic)Gupima Ingano)
1. Gusubiza ibintu neza
Gusubiza inyuma bivuga ubushobozi bwa fotodiode mu guhindura ibimenyetso by'urumuri mo fotoyo, ari na cyo gipimo cy'imbaraga z'urumuri ku bushobozi bw'urumuri. Guhitamo fotodiode ifite ubushobozi bwo gusubiza hejuru bishobora kongera ubushobozi bwa fotoyode ipima urumuri.

2. Ubugari bw'umuyoboro (bandwidth)
Bandwidth igaragaza frequency y'ikimenyetso aho amplitude y'ikimenyetso cyo gusohora cya Balance Photodetector ibora ho -3dB, kandi ifitanye isano n'ubushobozi bwa parasite bwa photodiode, ingano ya transimpedance, n'umusaruro wa gain bandwidth wa amplifier y'imikorere.
3. Igipimo cyo kwanga uburyo busanzwe
Igipimo cyo kwanga uburyo busanzwe gikoreshwa mu gupima urwego rwo kugabanya ibimenyetso by’uburyo busanzwe hakoreshejwe ibikoresho bipima ubuziranenge, kandi ibicuruzwa by’ubucuruzi muri rusange bisaba ko kwanga uburyo busanzwe nibura 25dB.
4. NEP
Imbaraga zingana n'urusaku: Imbaraga z'ikimenyetso cy'injira zikenewe ku gipimo cy'ikimenyetso hagati y'urusaku na 1, kikaba ari ikintu cy'ingenzi mu gupima imikorere y'urusaku rwa sisitemu. Ibice by'ingenzi by'urusaku rw'ikoranabuhanga ni urusaku rwo gukwirakwiza urumuri n'urusaku rw'amashanyarazi.

Gukoresha imashini ipima imiterere y'amafoto (Optoelectronic Balance Detector)
Mu myaka ya vuba aha, Balance Photodetector yakoreshejwe cyane mu nzego nka laser wind radar, laser vibration measure, fiber optic sensing, weak light coherent detection, spectral detection, gaz detection, nibindi. Ubushakashatsi ku muvuduko mwinshi, bandwidth nyinshi, urusaku ruto, high common mode rejection ratio, hamwe na balanced sensitization nyinshi zakoze iterambere kandi burimo gutera imbere mu rwego rwo guhuza cyane no gukoresha ingufu nke kugira ngo hahuzwe n’ibintu bitandukanye bikoreshwa.
