Isesengura ry'inshuro Er: Ibikoresho byo kohereza ikirahure bya Laser

Muri sisitemu z'amajwi nka laser ranging, LiDAR, no kumenya intego, Er: Glass laser transmitters ikoreshwa cyane mu gisirikare no mu baturage bitewe n'umutekano wayo mu maso no kuba yizewe cyane. Uretse ingufu zo gutera kw'amajwi, umuvuduko wo gusubiramo (frequency) ni ikintu cy'ingenzi mu gusuzuma imikorere. Igira ingaruka kuri laser.'umuvuduko w'igisubizo, ubwinshi bw'amakuru aboneka, kandi bifitanye isano rya hafi n'imicungire y'ubushyuhe, imiterere y'amashanyarazi, n'ubudahangarwa bwa sisitemu.

1. Inshuro zikoreshwa na laser ni zingahe?

Ingano ya laser yerekeza ku mubare w'imivuduko isohoka kuri buri gice cy'igihe, ubusanzwe ipimwa muri hertz (Hz) cyangwa kilohertz (kHz). Izwi kandi nk'igipimo cyo gusubiramo, ni ikimenyetso cy'ingenzi cy'imikorere ya lasers zikoresha pulse.
Urugero: 1 Hz = 1 laser pulse ku isegonda, 10 kHz = 10.000 laser pulses ku isegonda. Inyinshi muri Er: Glass lasers zikora mu buryo bwa pulsed, kandi inshuro zazo zifitanye isano rya hafi n'ishusho y'umuvuduko w'ingufu, isuzuma rya sisitemu, no gutunganya echo target.

2. Ingano rusange ya Er:Laser z'ikirahure

Bitewe na laser'Mu bijyanye n'imiterere n'ibisabwa mu mikorere, Er: Ibyuma byo kohereza laser bya Er: Ikirahure bishobora gukora kuva kuri single-shot mode (kugeza kuri 1 Hz) kugeza kuri kilohertz icumi (kHz). Frequencies zo hejuru zishyigikira gushakisha vuba, gukurikirana buri gihe, no kubona amakuru menshi, ariko kandi binasaba ingufu nyinshi, gucunga ubushyuhe, no kumara igihe kirekire muri laser.

3. Ibintu by'ingenzi bigira ingaruka ku gipimo cyo gusubiramo

①Igishushanyo mbonera cy'isoko ry'ipompo n'ingufu

Isoko ry'ipompe ya laser diode (LD) rigomba gushyigikira modulation yihuta cyane kandi rigatanga ingufu zihamye. Module z'amashanyarazi zigomba kuba zifite ubushobozi bwo kwakira no gufunga inshuro nyinshi.

②Imicungire y'ubushyuhe

Uko inshuro nyinshi zigenda ziyongera, niko ubushyuhe bwinshi butangwa kuri buri gipimo. Ibikoresho bipima ubushyuhe neza, kugenzura ubushyuhe bwa TEC, cyangwa imiterere yo gukonjesha ya microchannel bifasha mu kubungabunga umusaruro uhoraho no kongera igihe cyo gukoresha igikoresho.

③Uburyo bwo Guhinduranya Q

Guhindura Q mu buryo bwa Passive (urugero, hakoreshejwe kristu za Cr:YAG) muri rusange bikwiriye kuri laser zifite frequency nke, mu gihe guhindura Q mu buryo bwa active (urugero, hamwe na acousto-optic cyangwa electro-optic modulators nka Pockels cells) bituma habaho frequency nyinshi hamwe n’uburyo bwo kugenzura bushobora gukorwa.

④Igishushanyo cya module

Imiterere mito kandi ikoresha imirasire ya laser ifasha mu kubungabunga ingufu z'imitsi no ku mirasire yo hejuru.

4. Ibyifuzo byo guhuza inshuro n'ikoreshwa

Uburyo butandukanye bwo gukoresha busaba inshuro zitandukanye zo gukoresha. Guhitamo igipimo gikwiye cyo gusubiramo ni ingenzi kugira ngo habeho imikorere myiza. Hano hari ingero zimwe na zimwe z'ikoreshwa n'inama zisanzwe:

①Ingufu nyinshi (1)–20 Hz)

Ni byiza cyane mu gukoresha laser igenda kure no mu gushyiraho intego, aho kwinjira no kudahungabana kw'ingufu ari ingenzi.

②Ingano iri hagati, Uburyo bw'ingufu buri hagati (50)–500 Hz)

Ikwiriye gukoreshwa mu nganda zitandukanye, mu bijyanye no kugenda mu mazi, no mu buryo bufite frequency iringaniye.

③Ingufu nyinshi, Uburyo bwo gukoresha ingufu nke (>1 kHz)

Ikwiriye cyane sisitemu za LiDAR zirimo gusesengura ibintu mu buryo bwa array, gukora point cloud, no gukora modelling ya 3D.

5. Imiterere y'ikoranabuhanga

Uko guhuza laser bikomeza gutera imbere, icyiciro gikurikira cy’ibikoresho byo kohereza laser bya Er:Ikirahure kirimo gutera imbere mu byerekezo bikurikira:

①Guhuza igipimo cyo gusubiramo kiri hejuru n'umusaruro uhamye
②Uburyo bwo kuyobora imodoka bufite ubwenge n'uburyo bwo kugenzura inshuro zihinduka
③Igishushanyo mbonera cyoroheje kandi gikoresha ingufu nke
④Imiterere y’igenzura ry’uburyo bubiri (double-control architectures) haba kuri frequency na energy, ituma habaho flexible mode switching (urugero, scanning/focus/tracking)

6. Umwanzuro

Ingano y'imikorere ni ikintu cy'ingenzi mu gushushanya no guhitamo imashini zitanga imiyoboro ya laser ya Er:Ikirahure. Ntabwo igena gusa imikorere myiza yo kubona amakuru no gusubiza ibitekerezo bya sisitemu, ahubwo inagira ingaruka ku buryo butaziguye ku micungire y'ubushyuhe n'igihe cy'ubuzima bwa laser. Ku bahanga mu by'ikoranabuhanga, gusobanukirwa uburinganire hagati y'ingano n'ingufu.—no guhitamo ibipimo bihuye n'ikoreshwa ryihariye—ni ingenzi mu kunoza imikorere ya sisitemu.

Twandikire kugira ngo umenye byinshi ku bicuruzwa byacu bitandukanye bya Er: Glass laser transmitter bifite frequencies zitandukanye n'ibipimo.'Turi hano kugira ngo tugufashe guhaza ibyo ukeneye by'umwuga mu bijyanye no gupima, gukoresha LiDAR, kugenda, no kurinda.
