Lo mshini uqukethe ikhanda lokulinganisa lemishini yokulinganisa ye-laser ultrasonic, i-laser ekhuthazayo, i-laser ekhanyayo kanye ne-convergence optical element esetshenziselwa ukuqoqa izibani ezibonakala ebusweni bepayipi ukuya ekhanda lokulinganisa.Ipharamitha yenqwaba ebalulekile yokukhiqizwa kwamapayipi ukushuba kodonga.Ngakho-ke kuyadingeka ukulinganisa nokuqapha ipharamitha yayo ngesikhathi sokukhiqizwa kwamapayipi.Kufanele udale inhlolovo ye-laser ultrasonic ukuze ulinganise ubukhulu bodonga lwepayipi lensimbi elishiselwe .Kuyindlela yokulinganisa esekelwe kumgomo we-pulse echo ukuze kuqinisekiswe ukushuba kodonga ngokulinganisa isikhathi sokusabalalisa se-ultrasonic pulse.

Le divayisi isebenzisa i-laser ekhuthazayo ezoholela ekushayeni kwe-ultrasonic ebusweni bepayipi.Futhi-ke le pulse ye-ultrasonic isakazeka epayipini futhi ibonise odongeni lwangaphakathi.Futhi singakwazi ukukala isignali ebuyela odongeni olungaphandle ngokubeka i-laser ekhanyayo ebheke phezulu kwepayipi.Lesi siginali esibonisiwe sizothunyelwa ku-interferometer lapho kukhona i-homocentric interferometer.Idivayisi yokuhlaziya nokucubungula iqinisekisa umehluko wesikhathi phakathi kwamasignali we-ultrasonic okufakwayo kanye namasignali abonisa ama-ultrasonic ukuze kutholwe inani lokujiya kodonga ngaphansi kwezimo zokwazi isivinini sokusabalalisa epayipini.

Ukuze wenze le divayisi ilinganise ubukhulu bodonga lweipayipi lensimbi elishiselwengokunembile nangokuzinza, kuyadingeka ukwenza idivayisi yokulinganisa i-laser ultrasonic isebenze ngaphansi kwesimo esingcono kakhulu sokusebenza.Futhi imfuneko yako ukuthi i-beam yokukhanya ethunyelwe nge-laser eshukumisayo kanye ne-laser yokukhanya ephuma ku-laser ekhanyayo kufanele ihlangane endaweni eyabelwe.Nokho, okokuqala, kufanele sizame konke okusemandleni ethu ukugcina ngokunembile ibanga phakathi kwepayipi lokulinganisa nekhanda lokulinganisa.Ngaphezu kwalokho, izinqubo ziye zafakazela ukuthi kunzima ukuqinisekisa isimo esingcono kakhulu sokusebenza ngaphansi kwesimo semvelo esingaphezulu, ikakhulukazi ngesikhathi sokugoqa, akunakwenzeka ukulungisa idivayisi yokulinganisa i-laser ultrasonic.Futhi lokhu kungenziwa kuphela ngokulawulwa okuvamile kwedivayisi.Uma kungenjalo, ibanga eliphakathi kwekhanda lokulinganisa nendawo engaphezulu yepayipi ledivayisi yokulinganisa ye-laser kufanele igcinwe enanini elifanele lenkomba ukuze kuqinisekiswe ukuthi ukukhanya kwe-laser okubonisiwe okuvela ebusweni bepayipi kungafaka kangcono idivayisi yokulinganisa.

Setha okungenani izinsiza ezimbili zokukhanya ezithumela ukukhanya okufanayo okunqwabelanisayo eyodwa futhi ezimiswe ezindaweni ezihlukene zekhanda lokulinganisa.Futhi okungenani izinsiza ezimbili zokukhanya zingagxilwa ekhanda lokulinganisa kanje futhi zilungiswe isiqondiso.Okungukuthi uma kunebanga langaphambili lepayipi nekhanda lokulinganisa, izibani ezihlanganisayo ezivela kulezi zinsiza ezimbili zokukhanya zizowela ebusweni bepayipi lensimbi ye-LSAW.Kungakhathaliseki ukuthi ibanga elide kangakanani phakathi kwekhanda nendawo, ungakwazi ukukala kalula ngendlela engenhla.Ngakho-ke, kungaqiniseka ukuthi idivayisi yokulinganisa i-laser ultrasonic inesimo esingcono kakhulu sokusebenza ngaphansi kwesimo sokugoqa, esithuthukisa ukukhiqiza kanye nekhwalithi yepayipi yensimbi eshiselwe.
