Ikoranabuhanga ryo gutahura imvugo hakoreshejwe laser
LaserGutahura imvugo iri kure: Guhishura imiterere y'uburyo bwo gutahura

Umurasira woroheje wa laser ubyina neza mu kirere, ushakisha amajwi ya kure bucece, ihame riri inyuma y'ubu "bumaji" bw'ikoranabuhanga bw'ejo hazaza ni iry'ibintu bidasanzwe kandi ryuzuyemo ubwiza. Uyu munsi, reka dukureho iri koranabuhanga ritangaje kandi dusuzume imiterere n'amahame yaryo meza. Ihame ryo kumenya ijwi rya laser rigaragara ku Ishusho ya 1 (a). Sisitemu yo kumenya ijwi rya laser igizwe na sisitemu yo gupima vibration ya laser n'intego yo gupima vibration idahuje. Dukurikije uburyo bwo kumenya urumuri rugaruka, sisitemu yo kumenya ishobora kugabanywamo ubwoko bwo kudahuza n'ubwoko bwo kudahuza, kandi igishushanyo mbonera cy'ishusho kigaragara ku Ishusho ya 1 (b) na (c).

ISHUSHO YA 1 (a) Ishusho y'urukiramende rw'amajwi yo gupima ijwi hakoreshejwe laser; (b) Ishusho y'icyitegererezo cy'uburyo bwo gupima ijwi hakoreshejwe laser idakoresha interferometric; (c) Ishusho y'ingenzi y'uburyo bwo gupima ijwi hakoreshejwe laser idakoresha interferometric

一. Sisitemu yo gutahura idahungabanya Gutahura idahungabanya ni umwihariko woroshye w'inshuti, binyuze mu kurabagirana kw'ubuso bw'ikintu kigamije, hamwe n'ingendo y'urumuri rwagaragaye ihinduka ry'impinduka mu gice cyo kwakira ubukana bw'urumuri cyangwa ishusho y'udusimba kugira ngo hapimwe neza uburyo ubuso bw'ikintu kigamije bunyuramo, hanyuma "bugakomeza bugana ku buryo bugororotse" kugira ngo hagerwe ku gupima ikimenyetso cy'ijwi kiri kure. Dukurikije imiterere y'icyakiriwe.icyuma gipima foto, sisitemu yo kudahungabanya ishobora kugabanywamo ubwoko bw'ingingo imwe n'ubwoko bw'urutonde. Ishingiro ry'imiterere y'ingingo imwe ni "kongera kubaka ikimenyetso cy'amajwi", ni ukuvuga ko guhindagura kw'ubuso bw'ikintu bipimwa hapimwa impinduka z'ubukana bw'urumuri rw'icyuma gipima bitewe n'impinduka z'icyerekezo cy'urumuri rugaruka. Imiterere y'urutonde rumwe ifite ibyiza byo kugabanuka, imiterere yoroshye, igipimo cyo hejuru cyo gupima no kongera kubaka ikimenyetso cy'amajwi mu gihe nyacyo hakurikijwe uko umuvuduko w'amashanyarazi uhagaze, ariko ingaruka za laser speckle zizasenya isano iri hagati y'ubukana bw'urumuri n'ubukana bw'urumuri rw'icyuma gipima, bityo bikabuza ikoreshwa rya sisitemu yo gutahura urugingo rumwe gusa. Imiterere y'urutonde yongera kubaka guhindagura kw'ubuso bw'ikintu binyuze muri algorithme yo gutunganya amashusho ya speckle, ku buryo sisitemu yo gupima guhindagura igira ubushobozi bwo guhuza neza n'ubuso bugoye, kandi ikagira ubunyangamugayo n'ubuhanga bwo hejuru.

Ikindi. Sisitemu yo gutahura ikibazo itandukanye n'uburyo bwo kutabangamira, uburyo bwo kumenya ikibazo bufite ubwiza butaziguye, ihame ni ugukoresha imirasire ya laser ku buso bw'ikintu kigamije, ubuso bw'ikintu bunyuze ku murongo w'urumuri rw'inyuma butanga impinduka mu cyiciro/impinduka, ikoreshwa ry'ikoranabuhanga ryo gupima impinduka/impinduka mu gihe cy'impinduka kugira ngo hagerwe ku gupima mikoro-mikoro. Kuri ubu, ikoranabuhanga rigezweho ryo kumenya hagati y'ibintu rishobora kugabanywamo amoko abiri hakurikijwe ihame ry'ikoranabuhanga ryo gupima imivuduko ya laser Doppler n'uburyo bwo kwivangavanga bwa laser bushingiye ku gupima ibimenyetso by'amajwi. Uburyo bwo gupima imivuduko ya Laser Doppler bushingiye ku ngaruka za Doppler za laser kugira ngo hamenyekane ikimenyetso cy'amajwi binyuze mu gupima impinduka ya Doppler iterwa no guhindagura kw'ubuso bw'ikintu kigamije. Ikoranabuhanga ryo kwivanga rya laser ripima kwimuka, umuvuduko, guhindagura n'intera y'ikintu kigamije binyuze mu kwemerera igice cy'urumuri rugaragara rw'ikintu kigamije kure kongera kwinjira muri resonator ya laser bigatuma habaho modulation y'uburebure n'impinduka mu murima wa laser. Ibyiza byayo biri mu bunini buto no mu buryo bworoshye bwo gupima vibration system, ndetse nolaser ifite imbaraga nkeishobora gukoreshwa mu kumenya ikimenyetso cy'amajwi kiri kure. Sisitemu yo gupima frequency-shift laser yivanga ubwayo yo kumenya ikimenyetso cy'amajwi kiri kure igaragara ku Ishusho ya 2.

ISHUSHO YA 2 Imbonerahamwe y'uburyo bwo gupima frequency-shift laser yivanga ubwayo

Nk'uburyo bw'ikoranabuhanga bw'ingirakamaro kandi bunoze, "ubumaji" bwa laser bukoresha imvugo iri kure ntabwo bushobora gusa mu rwego rwo gutahura, ahubwo bunafite imikorere myiza kandi ikoreshwa mu buryo bwagutse - ikoranabuhanga ryo kurwanya ihohoterwa rishingiye kuri laser. Iri koranabuhanga rishobora kugera ku ntera zo kurwanya ihohoterwa rishingiye kuri laser ku rwego rwa metero 100 mu nzu, mu biro no mu zindi nkuta z'amadirishya y'ibirahure, kandi igikoresho kimwe gishobora kurinda neza icyumba cy'inama gifite ubuso bwa metero kare 15, hiyongereyeho umuvuduko wihuse wo gusuzuma no gushyira mu mwanya mu masegonda 10, kumenya neza aho ibintu biherereye ku kigero cyo hejuru kirenga 90%, no kwizera cyane akazi gahoraho. Ikoranabuhanga ryo kurwanya ihohoterwa rishingiye kuri laser rishobora gutanga icyizere gikomeye ku mutekano w'amakuru y'abakoresha mu biro by'ingenzi by'inganda n'ibindi bintu.
