Amakuru - Idirishya ryumukara kuri Lidar / DMS / OMS / Tof Module (1)

Kuva mu modoka ya kera ya Tof kuri Lidar kuri DMS iriho, bose bakoresha itsinda rya Infrared:

Tof module (850nm / 940nm)

Lidar (905nm / 1550nm)

DMS / OMS (940NM)

Mugihe kimwe, idirishya rya optique ni igice cyinzira nziza ya detector / yakira. Imikorere nyamukuru ni ukurinda ibicuruzwa mugihe wandika laser yuburebure bwihariye bwasohoye na laser inkomoko ya laser, no gukusanya imiraba yamenyekanye binyuze mumadirishya.

Idirishya rigomba kugira imirimo yibanze ikurikira:

1. Hasi bigaragara umukara kugirango uhangane ibikoresho bya optoelectronic inyuma yidirishya;

2. Ubutaka rusange bugaragaza idirishya rya optique ni bike kandi ntibizatera gutekereza neza;

3. Ikora neza kumatsinda ya Laser. Kurugero, kubisanzwe kuri 905nm laser detector, kohereza idirishya mumatsinda 905nm birashobora kugera kuri 95%.

4. Akazu kangiza, kunoza ibimenyetso-ku rusaku rw'ibitabo, no kuzamura ubushobozi bwo gutahura.

Ariko, lidar na DMS ni ibicuruzwa byombi, kuburyo ibicuruzwa byidirishya bishobora kubahiriza ibisabwa, byasubiye inyuma isoko yinyuma, kandi isura yumukara yabaye ikibazo.

01. Incamake y'ibisubizo by'idirishya kuri ubu ku isoko

Hariho ubwoko butatu:

Ubwoko bwa 1: Substrate ikozwe mubikoresho byashyizwe ahagaragara

Ubu bwoko bwibikoresho ni umukara kuko birashobora gukurura urumuri rugaragara no kohereza hafi-infrared band ya 90% (nka 905nm mumatsinda ya infrared) hamwe na 10%.

Ubu bwoko bwibikoresho burashobora gukoresha infrared Postparent Resin Pastrates, nka Bayer Makrolon PC 2405, ariko ibisigisigi bikunze gutondekanya amashusho ya Optique, kandi ntibishobora gutondekanya ibidukikije bikaba bifatika, kandi ntibishobora gutondekanya ibidukikije bikaba byiza, bityo ubundi buryo bwo guhoberana bukabije, kandi rero ubu bwoko bwa Shorshing Ntukeneye gushyushya.

Urashobora kandi guhitamo Schott RG850 cyangwa Igishinwa HWB850 ikirahure cyirabura, ariko ikiguzi cyubu bwoko bwikirahure cyirabura ni kinini. Gufata ikirahure cya HWB850 nkurugero, igiciro cyacyo kirenze inshuro 8 optique yikirahure kimwe, kandi ibyinshi mubicuruzwa ntibishobora kurenga kuri rohs ext na none ntishobora gukoreshwa kuri Windows yakozwe muri lidar.

Ubwoko bwa 2: Ukoresheje Ink yometse

Ubu bwoko bwa infrad yinjira yinjira akuramo urumuri rugaragara kandi rushobora kohereza imitwe ya infrant, hamwe na 80% kuri 90%, hamwe nurwego rusange rwoherezwa, hamwe nurwego rwoherejwe muri rusange ni hasi. Byongeye kandi, inyuma yinyo ihujwe na optique, ibijyanye no kurwanya ikirere ntibishobora gutsinda ibisabwa bikabije ikirere (nko kwipimisha ubushyuhe bukabije bukoreshwa mubindi bicuruzwa bifite ibikoresho byo kurwanya ikirere bifite isuku hamwe na kamera.
Ubwoko bwa 3: Gukoresha umwirabura
Akayunguruzo k'umukara ni akayunguruzo kashobora guhagarika urumuri rugaragara kandi rutanduza cyane kuri bande ya nir (nka 905nm).

Akayunguruzo k'umukara kagenewe hamwe na silicon hydride, silicon okiside nibindi bikoresho bya firime bito, kandi byateguwe ukoresheje tekinoroji ya Magnetron. Irangwa nimikorere ihamye kandi yizewe kandi irashobora gukorwa misa. Kugeza ubu, ibisobanuro bisanzwe bya Optique Akayunguruzo Filime muri rusange ukoreshe imiterere isa na firime yoroheje. Munsi yuburyo busanzwe bwa silicon ya silicon. Igitekerezo gisanzwe ni ukugabanya kwinjiza hydride ya silicon, cyane cyane kwinjiza itsinda ryabanjirije iyi, kugirango habeho gusubizwa mu itsinda rya 905NM nka 1550nm.
