Lumispot Technology Co., Ltd., ishingiye ku bushakashatsi n'iterambere ry'imyaka myinshi, yakoze neza laser ntoya kandi yoroheje ifite ingufu za 80mJ, inshuro zo gusubiramo za 20 Hz n'uburebure bw'umurambararo butagira ingaruka ku maso bw'umuntu bwa 1.57μm. Ubu bushakashatsi bwagezweho binyuze mu kongera ubushobozi bwo kuganira bwa KTP-OPO no kunoza umusaruro wa module ya laser ya diode ya pompe. Dukurikije ibyavuye mu isuzuma, iyi laser yujuje ubushyuhe bwinshi bwo gukora kuva kuri -45 ℃ kugeza kuri 65 ℃ hamwe n'imikorere myiza, igera ku rwego rwo hejuru mu Bushinwa.
Pulsed Laser Rangefinder ni igikoresho gipima intera kubera inyungu ya laser pulse yerekejwe ku ntego, gifite akamaro ko gupima ahantu hatandukanye neza, ubushobozi bukomeye bwo kurwanya ingaruka mbi n'imiterere mito. Iki gicuruzwa gikoreshwa cyane mu gupima no mu bindi bice. Ubu buryo bwo gupima ahantu hatandukanye bwa pulsed laser bukoreshwa cyane mu gupima intera ndende. Muri ubu buryo bwo gupima ahantu hatandukanye, ni byiza guhitamo laser ifite ingufu nyinshi n'inguni nto yo gukwirakwiza, hakoreshejwe ikoranabuhanga rya Q-switching kugira ngo ikore pulses za nanosecond laser.
Imiterere y'ingenzi ya pulsed laser rangefinder ni iyi ikurikira:
(1) Imashini ikoresha laser irinda amaso y’umuntu: 1.57um optical parametric oscillator igenda isimbura buhoro buhoro aho ikoresha laser isanzwe ya 1.06um wavelength rangefinder mu bice byinshi by’ikoranabuhanga.
(2) Imashini ntoya ya laser iri kure ifite ubushobozi bwo gupima uburebure ifite uburemere buto kandi bworoheje.
Bitewe no kunoza imikorere ya sisitemu yo gutahura no gufata amashusho, hakenewe ibikoresho byo gupima imirasire ya laser biri kure bishobora gupima intego ntoya za 0.1m² hejuru ya kilometero 20. Kubwibyo, ni ngombwa kwiga ibikoresho byo gupima imirasire ya laser bifite imikorere myiza.
Mu myaka ya vuba aha, Lumispot Tech yashyize imbaraga mu bushakashatsi, gushushanya, gukora no kugurisha laser ya 1.57um wavelength irinda amaso ifite inguni nto yo gukwirakwiza urumuri n'imikorere myiza.
Vuba aha, Lumispot Tech, yakoze laser ikonjesha mu kirere ya 1.57um ifite imbaraga nyinshi kandi ikora neza, bitewe n’uko ubushakashatsi bwakozwe mu gupima intera ndende ya laser rangefinder butanga umusaruro mwinshi. Nyuma y’igerageza, iyi laser igaragaza uburyo bwo kuyikoresha mu buryo burambuye, ifite imikorere myiza, ihangana n’ibidukikije mu bushyuhe bwinshi kuva kuri dogere selisiyusi 40 kugeza kuri dogere selisiyusi 65,
Binyuze muri iki gipimo gikurikira, hamwe n'ingano idahinduka y'ibindi bisobanuro, binyuze mu kunoza imbaraga zo gusohora uburebure no kugabanya inguni yo gukwirakwiza imirasire, bishobora kunoza intera yo gupima uburebure bw'umurasire. Kubera iyo mpamvu, ibintu 2: agaciro k'imbaraga zo gusohora uburebure n'inguni nto yo gukwirakwiza imirasire, laser ifite imiterere iciriritse hamwe n'imikorere ikonjesha umwuka ni cyo gice cy'ingenzi kigena ubushobozi bwo gupima intera y'umurasire runaka.
Igice cy'ingenzi cyo gukoresha laser hakoreshejwe uburebure bw'umurambararo butagira ingaruka ku jisho ry'umuntu ni uburyo bwa optical parametric oscillator (OPO), harimo guhitamo kristalo idakoresha umurongo umwe, uburyo bwo guhuza ibice n'igishushanyo mbonera cya OPO interiol. Guhitamo kristalo idakoresha umurongo umwe biterwa n'uburyo bunini butagira ingaruka ku murongo umwe, urwego rwo kwirinda kwangirika cyane, imiterere ihamye ya shimi n'iy'umubiri hamwe n'uburyo bwo gukura bumaze gukura n'ibindi, guhuza ibice bigomba kujya imbere. Hitamo uburyo butari ingenzi bwo guhuza ibice bufite inguni nini yo kwakira n'inguni nto yo kuvaho; Imiterere ya OPO igomba kwita ku bushobozi n'ubwiza bw'imirasire hashingiwe ku kwemeza ko ari ingirakamaro. Impinduka z'uburebure bw'umurambararo wa KTP-OPO hamwe n'inguni yo guhuza ibice, iyo θ = 90 °, urumuri rw'ikimenyetso rushobora gusohora neza laser idakoresha umurongo umwe. Kubwibyo, kristalo yakozwe icibwa ku ruhande rumwe, guhuza inguni hakoreshejwe θ = 90 °, φ = 0 °, ni ukuvuga gukoresha uburyo bwo guhuza urwego, iyo kristalo idakoresha umurongo umwe ari yo nini kandi nta ngaruka zo gutatana.
Hashingiwe ku gusuzuma neza iki kibazo cyavuzwe haruguru, hamwe n’urwego rw’iterambere ry’ikoranabuhanga rya laser n’ibikoresho byayo, igisubizo cya tekiniki cyo kunoza ni iki: OPO ikoresha igishushanyo cya KTP-OPO cyo mu cyiciro cya kabiri kidashingiye ku ngingo z’ingenzi; KTP-OPO ebyiri zikozwe mu buryo buhagaze mu buryo bugororotse kugira ngo zinoze imikorere yo guhindura no kwizerwa kwa laser nk’uko bigaragara muriIgishushanyo cya 1Hejuru.
Isoko ya pompe niyo yikorera ubushakashatsi ubwayo kandi yateje imbere umurongo wa laser ya semiconductor condensate, ifite cycle y'akazi ka 2% byibuze, ingufu za 100W kuri single bar n'imbaraga zose zo gukora za 12.000W. Prism y'inguni y'iburyo, indorerwamo igaragara neza hamwe na polarizer bikora umwobo uvanze wa polarization, kandi prism y'inguni y'iburyo na waveplate birazunguruka kugira ngo haboneke umusaruro wifuzwa wa laser wa 1064 nm. Uburyo bwa Q modulation ni modulation ya Q electro-optical ikora ishingiye kuri crystal ya KDP.
Igishushanyo cya 1Amakristaro abiri ya KTP ahujwe mu buryo bukurikiranye
Muri iki kigereranyo, Prec ni yo mbaraga ntoya cyane zishobora kumenyekana;
Pout ni agaciro gakomeye k'umusaruro w'imbaraga z'akazi;

Igishushanyo cya 2: Moduli y'umurongo w'umurongo ufite ishusho ya arc binyuze mu iterambere ryigenga,
hagati hari inkoni ya kristu ya YAG.
ItsindaIgishushanyo cya 2ni imitako y'imirongo ifite ishusho ya arc, ishyiramo inkoni za kristu za YAG nk'uburyo bwa laser imbere muri module, hamwe n'icyitegererezo cya 1%. Kugira ngo hakemurwe ikibazo kiri hagati y'uburyo laser igenda n'uburyo laser ikwirakwira, hakoreshejwe uburyo bwa LD array ku nguni ya dogere 120. Isoko ya pompe ni uburebure bwa 1064nm, module ebyiri za 6000W curved array bar muri seriviseur tandem pumping. Ingufu zisohoka ni 0-250mJ hamwe n'ubugari bwa pulse bwa 10ns n'umuvuduko munini wa 20Hz. Hakoreshwa umwobo upfundikiwe, kandi laser ya 1.57μm wavelength isohoka nyuma ya tandem KTP nonlinear crystal.
Imbonerahamwe ya 3Igishushanyo mbonera cya laser ya pulsed ya wavelength ya 1.57um

Guhindura igipimo cy'ingufu za laser kugira ngo hapimwe imbaraga z'umusaruro w'ubwoko bubiri bw'uburebure bw'umurambararo. Dukurikije imbonerahamwe igaragara hepfo, agaciro k'ingufu kari impuzandengo y'agaciro kari munsi ya 20Hz hamwe n'igihe cy'umunota 1 cyo gukora. Muri zo, ingufu zikomoka kuri laser ya wavelenth ya 1.57um zifite impinduka ikurikiranye n'isano iri hagati y'ingufu z'ipompe y'uburebure bwa 1064nm. Iyo ingufu z'isoko rya pompe zingana na 220mJ, ingufu zisohoka za laser ya wavelenth ya 1.57um zishobora kugera kuri 80mJ, aho igipimo cyo guhindura kigera kuri 35%. Kubera ko urumuri rwa OPO rukorwa hifashishijwe imbaraga runaka z'urumuri rw'ibanze, agaciro karwo kari hejuru y'agaciro k'urumuri rw'ibanze rwa 1064 nm, kandi ingufu zisohoka ziyongera vuba nyuma y'uko ingufu zisohoka zirenze agaciro k'urugero rwa OPO. Isano iri hagati y’ingufu zisohoka za OPO n’imikorere myiza yazo hamwe n’ingufu z’urumuri rw’ibanze rusohoka zigaragazwa ku ishusho, aho bigaragara ko ubushobozi bwo guhindura OPO bushobora kugera kuri 35%.
Amaherezo, umuvuduko wa laser pulse wa 1.57μm w'uburebure ufite ingufu zirenze 80mJ n'ubugari bwa laser pulse bwa 8.5ns ushobora kugerwaho. Inguni y'itandukaniro ry'umuvuduko wa laser unyura muri laser beam expander ni 0.3mrad. Isesengura n'ubushobozi bwo gupima uburebure bw'icyuma gipima laser pulsed rangefinder gikoresha iyi laser bushobora kurenza 30km.
