Iimodyuli zokulinganisa umgama weLaser zizixhobo ezichaneke kakhulu ezisetyenziswa ngokubanzi kwiinkalo ezinjengokuqhuba ngokuzimela, iidrones, i-industrial automation, kunye nerobhothi. Umgaqo wokusebenza kwezi modyuli ngokuqhelekileyo ubandakanya ukukhutshwa kwe-laser beam kunye nokulinganisa umgama phakathi kwento kunye nenzwa ngokufumana ukukhanya okubonakalisiweyo. Phakathi kweeparitha ezahlukeneyo zokusebenza zeemodyuli zokulinganisa umgama we-laser, ukuhlukana kwe-beam yinto ebalulekileyo echaphazela ngokuthe ngqo ukuchaneka komlinganiselo, uluhlu lokulinganisa, kunye nokukhethwa kweemeko zesicelo.
1. Ingcamango esisiseko ye-Beam Divergence
Ukwahlukana kwe-Beam kubhekiselele kwi-angle apho umqa we-laser unyuka ngobukhulu be-cross-sectional size njengoko uhamba ngokude kwi-laser emitter. Ngamagama alula, i-divergence encinci ye-beam, i-laser beam egxininiswe ngakumbi ihlala ngexesha lokusasaza; ngokuchaseneyo, ubukhulu bokwahlukana komqadi, i-beam isasazeka ngokubanzi. Kwizicelo ezisebenzayo, ukuhlukana kwe-beam ngokuqhelekileyo kubonakaliswe kwii-angles (iidigri okanye i-milliradians).
Ukwahlukana kwe-laser beam kumisela ukuba isasazeka kangakanani kumgama onikiweyo, nto leyo echaphazela ubungakanani bendawo kwinto ekujoliswe kuyo. Ukuba ukuhlukana kukhulu kakhulu, umqadi uya kugubungela indawo enkulu kumgama omde, onokunciphisa ukuchaneka komlinganiselo. Ngakolunye uhlangothi, ukuba ukuhlukana kuncinci kakhulu, umqadi unokugxila kakhulu kumgama omde, okwenza kube nzima ukubonakalisa ngokufanelekileyo okanye ukuthintela ukufunyanwa komqondiso obonakalisiweyo. Ke ngoko, ukukhetha ukwahluka okufanelekileyo komqadi kubalulekile kukuchaneka kunye noluhlu lwesicelo semodyuli yokulinganisa umgama we-laser.
2. Impembelelo yokwahluka kweBeam kwiModyuli yoMgama womgama weLaser
Ukwahlukana kwe-Beam kuchaphazela ngokuthe ngqo ukuchaneka komlinganiselo wemodyuli yomgama we-laser. Umahluko omkhulu womqadi ukhokelela kubukhulu bendawo enkulu, nto leyo enokukhokelela ekukhanyeni okuthe saa kunye nemilinganiselo engachanekanga. Kwimigama emide, ubungakanani bendawo enkulu bunokwenza buthathaka ukukhanya okubonakalisiweyo, okuchaphazela umgangatho wesignali ofunyenwe sisiva, ngaloo ndlela ukwandisa iimpazamo zomlinganiselo. Ngokwahlukileyo, ukwahluka komqadi omncinci kugcina umqadi welaser ugxile kumgama omde, okukhokelela kubungakanani obuncinci bendawo kwaye ngenxa yoko ukuchaneka komlinganiselo ophezulu. Kwizicelo ezifuna ukuchaneka okuphezulu, okufana nokuskena kwelaser kunye nokubekwa kwindawo echanekileyo, ukwahluka komqadi omncinci ngokuqhelekileyo lolona khetho lukhethwayo.
Ukwahlukana kweBeam kukwanxulumene ngokusondeleyo kuluhlu lokulinganisa. Kwiimodyuli zomgama we-laser kunye nokwahlukana okukhulu kwe-beam, i-laser beam iya kusasazeka ngokukhawuleza kwimigama emide, yenza buthathaka isignali ebonakalisiweyo kwaye ekugqibeleni inciphise uluhlu olusebenzayo lokulinganisa. Ukongeza, ubungakanani bendawo enkulu bunokubangela ukukhanya okubonakalisiweyo kuvela kwiindlela ezininzi, okwenza kube nzima kwinzwa ukuba ifumane ngokuchanekileyo umqondiso osuka kwindawo ekujoliswe kuyo, nto leyo echaphazela iziphumo zomlinganiselo.
Kwelinye icala, ukwahluka komqadi omncinci kunceda umqadi welaser ukuba uhlale ugxile, uqinisekisa ukuba ukukhanya okubonakalisiweyo kuhlala kunamandla kwaye ngaloo ndlela kwandisa uluhlu olusebenzayo lokulinganisa. Ke ngoko, okukhona kuncinci ukwahluka komqadi wemodyuli yokulinganisa umgama welaser, kokukhona uluhlu olusebenzayo lokulinganisa luyanda.
Ukukhethwa kokwahlukana kwe-beam kwakhona kuboshwe ngokusondeleyo kwimeko yesicelo semodyuli yokulinganisa umgama we-laser. Kwiimeko ezifuna imilinganiselo emide kunye neyokuchaneka okuphezulu (njengokubonwa komqobo ekuqhubeni ngokuzimeleyo, i-LiDAR), imodyuli ene-divergence encinci ye-boam ikhethwa ngokuqhelekileyo ukuqinisekisa imilinganiselo echanekileyo kwimigama emide.
Ukulinganisa umgama omfutshane, ukuskena, okanye ezinye iisistim ezizenzekelayo kwimizi-mveliso, imodyuli enokwahlukana okukhulu komqadi kunokukhethwa ukwandisa indawo yokugubungela kunye nokuphucula ukusebenza komlinganiselo.
Ukwahlukana kweBeam kukwaphenjelelwa ziimeko zokusingqongileyo. Kwiindawo eziyinkimbinkimbi kunye neempawu ezibonakalisiweyo ezinamandla (ezifana nemigca yemveliso yezoshishino okanye ukuskena isakhiwo), ukusasazeka kwe-laser beam kunokuchaphazela ukubonakalisa kunye nokwamkela ukukhanya. Kwiimeko ezinjalo, ukuhlukana okukhulu kwe-boam kunokuncedisa ngokugubungela indawo enkulu, ukwandisa amandla omqondiso ofunyenweyo, kunye nokunciphisa ukuphazamiseka kokusingqongileyo. Ngakolunye uhlangothi, kwiindawo ezicacileyo, ezingabonakaliyo, ukuhlukana kwe-boam encinci kunokuncedisa ukugxininisa umlinganiselo kwithagethi, ngaloo ndlela kuncitshiswe iimpazamo.
3. Ukukhethwa kunye noyilo lweBeam Divergence
Ukwahlukana kwe-beam yemodyuli yokulinganisa umgama we-laser ngokuqhelekileyo kumiselwa kuyilo lwe-laser emitter. Iimeko ezahlukeneyo zesicelo kunye neemfuno zikhokelela kukwahluka kuyilo lokwahlukana kwe-beam. Apha ngezantsi kukho iimeko ezininzi eziqhelekileyo zesicelo kunye nokukhetha kwazo okudityanisiweyo kokwahluka komqadi:
- Ukuchaneka okuPhezulu kunye noMlinganiselo woLunge olude:
Kwizicelo ezifuna ukuchaneka okuphezulu kunye nemigama emide yokulinganisa (efana nemilinganiselo echanekileyo, i-LiDAR, kunye nokuqhuba ngokuzimeleyo), ukwahluka komqadi omncinci kuyakhethwa ngokubanzi. Oku kuqinisekisa ukuba i-laser beam igcina ubungakanani bendawo encinci kwimigama emide, iphucula zombini ukuchaneka komlinganiselo kunye noluhlu. Umzekelo, ekuqhubeni ngokuzimeleyo, ukwahluka komqadi kwiinkqubo ze-LiDAR ngokuqhelekileyo kugcinwa ngaphantsi kwe-1 ° ukuze kubonwe ngokuchanekileyo imiqobo ekude.
- Ukhuseleko olukhulu oluneeMfuno eziChanekileyo ezisezantsi:
Kwiimeko apho kufuneka indawo enkulu yokhuselo, kodwa ukuchaneka akubalulekanga kangako (okufana nokufakwa kwerobhothi yalapha kunye nokuskena okusingqongileyo), umahluko omkhulu womqadi udla ngokukhethwa. Oku kuvumela umqa welaser ukuba ugqume indawo ebanzi, uphucula amandla okuva kwesixhobo, kwaye uwenze ulungele ukuskena okukhawulezayo okanye ubhaqo lwendawo enkulu.
- Umlinganiselo wangaphakathi woMgama oMfutshane:
Kwimilinganiselo yangaphakathi okanye yoluhlu olufutshane, ukwahlukana okukhulu kwe-boam kunokuncedisa ukwandisa ukugquma kwe-laser beam, ukunciphisa iimpazamo zokulinganisa ngenxa yee-engile zokubonisa ngokungafanelekanga. Kwiimeko ezinjalo, ukuhlukana okukhulu kwe-boam kunokuqinisekisa iziphumo ezizinzileyo zokulinganisa ngokunyusa ubungakanani bendawo.
4. Isiphelo
Ukwahlukana kweBeam yenye yezinto eziphambili ezichaphazela ukusebenza kweemodyuli zokulinganisa umgama we-laser. Ichaphazela ngokuthe ngqo ukuchaneka komlinganiselo, uluhlu lokulinganisa, kunye nokukhethwa kweemeko zesicelo. Uyilo olufanelekileyo lokuhlukana kwe-beam kunokuphucula ukusebenza ngokubanzi kwemodyuli yokulinganisa umgama we-laser, ukuqinisekisa ukuzinza kwayo kunye nokusebenza kakuhle kuzo zonke izicelo. Njengoko itekhnoloji yokulinganisa umgama we-laser iqhubeka nokuguquguquka, ukulungelelanisa ukuhlukana kwe-beam kuya kuba yinto ebalulekileyo ekwandiseni uluhlu lwesicelo kunye namandla okulinganisa kwezi modyuli.
