Ukunemba kokulinganisa komshini wokulinganisa umbono kuzothinteka yizimo ezintathu, okuyiphutha lokukhanya, iphutha lomshini kanye nephutha lokusebenza komuntu.
Iphutha lomshini lenzeka kakhulu enqubweni yokukhiqiza nokuhlanganisa umshini wokulinganisa umbono. Singalinciphisa ngempumelelo leli phutha ngokuthuthukisa ikhwalithi yokuhlanganisa ngesikhathi sokukhiqiza.
Okulandelayo yizinyathelo zokuphepha zokugwema amaphutha emishini:
1. Uma ufaka i-guide rail, isisekelo sayo kumele sibe nezinga elanele, futhi kudingeka kusetshenziswe inkomba yokudayela ukulungisa ukunemba kwezinga layo.
2. Uma ufaka ama-rulers e-X axis grating, kumele futhi agcinwe esimweni esivundlile ngokuphelele.
3. Ithebula lokusebenza kumele lilungiswe ngokwezinga kanye nokuma, kodwa lokhu kuwukuhlolwa kwekhono lochwepheshe lokuhlanganisa.
Iphutha lokubona liwukuhlanekezela nokuhlanekezela okudalwa phakathi kwendlela yokubona kanye nezingxenye ngesikhathi sokuthwebula izithombe, okuhlobene kakhulu nenqubo yokukhiqiza ikhamera. Isibonelo, lapho ukukhanya kwesigameko kudlula kulensi ngayinye, kukhiqizwa iphutha lokubona kanye nephutha lesikhundla se-lattice se-CCD, ngakho-ke uhlelo lokubona lunokuhlanekezela okungaqondile kwe-geometric, okuholela ezinhlotsheni ezahlukene zokuhlanekezela kwe-geometric phakathi kwephuzu lesithombe esiqondiwe kanye nephuzu lesithombe eliyinkolelo.
Okulandelayo isingeniso esifushane sezinto eziningana ezihlanekezelwe:
1. Ukuphambuka kwemisebe: Ngokuyinhloko kuyinkinga yokulingana kwe-axis eyinhloko yelensi yekhamera, okungukuthi, amaphutha e-CCD kanye nesimo selensi.
2. Ukuhlanekezela kwe-Eccentric: Isizathu esiyinhloko ukuthi izikhungo ze-optical axis zelensi ngayinye azikwazi ukuba yi-collinear kuphela, okuholela ezikhungweni ze-optical ezingaguquguquki kanye nezikhungo ze-geometric zesistimu ye-optical.
3. Ukuhlanekezelwa kwe-prism encane: Kufana nokwengeza i-prism encane ohlelweni lwe-optical, okungeke nje kubangele ukuphambuka kwe-radial, kodwa futhi nokuphambuka kwe-tangential. Lokhu kungenxa yokwakheka kwelensi, amaphutha okukhiqiza, kanye namaphutha okufakwa kwemishini.
Elokugcina iphutha lomuntu, elihlobene kakhulu nemikhuba yokusebenza yomsebenzisi futhi ikakhulukazi lenzeka emishinini esetshenziswa ngesandla kanye nemishini ezenzakalelayo kancane.
Iphutha lomuntu lihlanganisa ikakhulukazi izici ezilandelayo:
1. Thola iphutha lesici sokulinganisa (imiphetho engacacile ne-burr)
2. Iphutha lokulungiswa kobude be-focal be-Z-axis (iphutha lokwahlulela okucacile kwephuzu lokugxila)
Ngaphezu kwalokho, ukunemba komshini wokulinganisa umbono nakho kuhlobene eduze nokusetshenziswa kwawo kaningi, ukulungiswa njalo kanye nendawo yokusetshenziswa. Amathuluzi okunemba adinga ukulungiswa njalo, agcine umshini womile futhi uhlanzekile uma ungasetshenziswa, futhi agcine kude nezindawo ezinokudlidliza noma umsindo omkhulu lapho uwusebenzisa.
