Kubyara Multi-Ubujyakuzimu bwa 3D Hologramamu Ukoresheje Urusobe rwuzuye rwa Neural Network

Umucyo utanga urumuri ni igikoresho cyiza gikoresha imiterere yacyo kugirango uhindure amplitude, icyiciro nibindi bipimo byumucyo winjiza munsi yubugenzuzi bugaragara, kandi ukabona urumuri ruteganijwe gukwirakwizwa kumurima wanyuma wakiriye ugenzura ingano nubuyobozi bwurumuri rwimbere hamwe nurumuri rwumucyo. Ikoreshwa ryumucyo utandukanya imiyoboro ya optique ya neural imiyoboro yatejwe imbere mumyaka mirongo, kandi hamwe nogutezimbere uburyo bwo guhindura modulitifike yumucyo uhinduranya hamwe no guhora tunonosora uburyo bwo kubara algorithm, ubushobozi bukomeye bwimiyoboro ya optique ya optique bwakomeje gushakishwa, hamwe nibishobora gukoreshwa muburyo bwo kureba imashini, gutunganya amashusho yubuvuzi, imiyoboro ya sensor optique nizindi nzego.

Uru rupapuro rugaragaza uburyo bwo kubyara ibice byinshi byimbitse bya holographe ukoresheje urusobe rw'imitsi rwuzuye (FCN). Uburyo bukubiyemo ahanini imbere-gusubira inyuma gutandukanya ibice byo kubara uburebure bwimbitse butandukanye, hamwe nuburyo bwo gusimbuza uburyo (L2RM) kugirango bikemure isano iri hagati. Imirima yatandukanijwe yabazwe nabambere igaburirwa muri FCN yateguwe neza, ikoresha imbaraga zayo zidafite umurongo zikwiranye no kubyara hologramamu yimbitse ya 3D igaragara. Iyanyuma irashobora kunoza ubwiza bwa hologramamu hiyongereyeho amakuru yibintu byafunzwe no koroshya imipaka yinzego zitandukanye muburyo bwo kwiyubaka. Kugaragaza imbaraga kandi zifite imbaraga za 3D bigerwaho mubigeragezo mugupakira mudasobwa yakozwe na mudasobwa (CGH) kumurongo wibanze wa moderi yumucyo (SLM).

Igice cyibikorwa byubushakashatsi nibisubizo byubushakashatsi:

Ikoreshwa rya lazeri idafite polarisiyumu ifite uburebure bwa 638 (± 8) nm n'imbaraga za mW 30 yakoreshejwe mu bushakashatsi, nkuko bigaragara ku gishushanyo cya 1.Ibisohoka bya fibre byashyizwe ahateganye na lens yegeranye ifite uburebure bwa mm 100 kugira ngo haboneke umurongo w’indege, kandi hifashishijwe akayunguruzo ka polarisi kugira ngo ubone umurongo. Isahani ya kimwe cya kabiri (HWP) yarazungurutswe kuburyo icyerekezo cya polarisiyonike yumucyo cyahujwe nicyerekezo cya LCOS collimation angle, hanyuma hagakurikiraho gushyiramo urukiramende kugirango ubone umwirondoro wurukiramende. Itara ryibyabaye ryahinduwe kandi ryerekanwa hakoreshejwe moderi yumucyo utandukanye (Zhongke Microstar FSLM-4K70-P02), kandi aho hantu hongeye kubakwa hifashishijwe ubunini bwakoreshejwe lens ya Fourier ifite uburebure bwa mm 100. Akayunguruzo kahantu gakoreshwa kuburyo icyifuzo cyo gutandukanya cyanyuze hamwe nandi mabwiriza yo gutandukanya arayungurura. Igice kinini cya 3D cyubatswe cyafashwe hakoreshejwe kamera.

Igishushanyo 1 Gushiraho igeragezwa (icyiciro cyubwoko bwimiterere yumucyo moderi, icyitegererezo: FSLM-4K70-P02)

Ibipimo byerekana imiterere yumucyo utandukanya ikoreshwa mubigeragezo nibi bikurikira:

Igishushanyo cya 2. Igisekuru cya 3D igishushanyo mbonera. A) 3D idasanzwe. B) Uburyo bwo gutoranya. C) Ishusho yimbaraga. D) Ishusho yimbitse. E) Dataset ya 3D ishushanyije.

Igishushanyo cya 3 Igisekuru cya hologramamu yimbitse hamwe na FCN. a) Kubara uburebure bwimbitse butandukanye imirima ukoresheje imbere-inyuma yo gutandukanya ibice. b) Imiterere ya FCN. c) Kubara ikosa ryimbitse.

Igishushanyo 4. Kugereranya ubuziranenge bwo kwiyubaka. A) Intego yerekanwe. B) Kwubaka muburyo bwuburyo busanzwe hamwe na L2RM. C) Kubaka neza uburyo busanzwe hamwe na L2RM.

Igishushanyo 5.Ibintu bigoye bya 3D hamwe na hologramamu ihuye. A) Ishusho yimbaraga na B) ishusho yimbitse yerekana 3D. C) Hologramu yimbitse yakozwe na FCN.

Igishushanyo cya 6. Kwubaka umubare no kwiyubaka kwa A) WH, B) DPH, na C) L2RM. Amashusho kumurongo 1, 3, na 5 yerekana kwiyubaka mubare, mugihe umurongo wa 2, 4, na 6 werekana kwiyubaka kwa optique. Mu nkingi ya 1 n'iya 2, kamera yibanda ku ndege yibanze (“umupira w'amaguru”) hamwe n'indege yibanze (“gitari”) ya “umupira-gitari”. Mu nkingi ya 3 n'iya 4, kamera yibanda ku ndege yibanze (“indege”) hamwe n'indege yibanze (“imbwa”) ya “indege-imbwa”.

Igishushanyo 7. Ibintu byubatswe ku ndege zitandukanye.

Byanditswe ku musozo:

Imiyoboro ya optique yitabiriwe cyane bitewe nubushobozi bwayo bwo kugereranya nini nini yo kubara, gukora imbaraga nke, no gusubiza byihuse, hamwe na modulator yumucyo wibikoresho nkibikoresho bitandukanya bigira uruhare runini mumiyoboro itandukanya imitsi kandi ikoreshwa mubice byinshi, nka 3D holographic imaging computing kuri AR / VR, amashusho y’ibinyabuzima, hamwe no kumva neza. Ukurikije gahunda yimikorere yimiyoboro itandukanya imiyoboro, imikorere ihanitse itandukanya imiyoboro yimitsi iteganijwe kugerwaho mugihe kizaza.
