Indlela iLaser Range esebenza ngayo

Ngokomgaqo osisiseko, kukho iintlobo ezimbini zeendlela zokusukela ngelaser: ixesha lokuhamba ngenqwelomoya (TOF) elisukela kunye nelingeloxesha lokubhabha. Naziipulsed laser rangekunye ne-laser-based laser esukela kwixesha lokuhamba ngenqwelomoya.

I-Pulse ranges yindlela yokulinganisa eyaqala ukusetyenziswa kwinkalo yovavanyo kunye nemephu ngobuchwepheshe belaser. Ngenxa yokuba i-angle ye-laser divergence incinci, ixesha le-laser pulse lifutshane kakhulu, kwaye amandla angoko nangoko makhulu kakhulu, ngoko anokufikelela kuluhlu olude kakhulu. Ngokuqhelekileyo, injongo yentsebenziswano ayisetyenziswanga, kodwa ukubonakaliswa okusasazeka kwesignali yokukhanya ngethagethi elinganisiweyo isetyenziselwa ukulinganisa umgama.

Umgaqo wendlela ye-pulsed range uqondwa kakuhle. Iwotshi ephezulu-frequency iqhuba ikhawuntala ukubala ixesha phakathi kokuthumela kunye nokufumana i-pulses, eyenza ixesha lewotshi yokubala libe lincinci kakhulu kunexesha eliphakathi kokuthumela kunye nokufumana i-pulses ukuqinisekisa ukuchaneka okwaneleyo, ngoko le ndlela yokulinganisa ifanelekile ixesha elide- umlinganiselo womgama.

I-angle yokukhutshwa kwe-laser ye-pulsed incinci, amandla agxininiswe kwindawo, kwaye amandla angoko nangoko makhulu. Ukusebenzisa ezi mpawu, ezahlukeneyo eziphakathi kunye nomgama omdelaser rangefinders, lidars, njl. zingenziwa. Okwangoku, i-laser ye-pulsed isetyenziswa ngokubanzi kwi-topographic kunye ne-geomorphological measurement, ukuhlola i-geological, ukulinganisa ukwakhiwa kobunjineli, umlinganiselo wokuphakama kwenqwelomoya, i-traffic kunye ne-logistics ...umlinganiselo womgama woshishinokunye neminye imiba yobugcisa.

Inqanaba laser ukusukakukusebenzisa ukuphindaphindeka kwebhendi yerediyo ukumodareyitha iamplitude yesibane selaser kunye nokulinganisa ukulibaziseka kwesigaba okwenziwa sisibane sokumodareyitha sibuyela emva naphambili kumgca wokulinganisa, kwaye emva koko uguqule umgama omelwe kukulibaziseka kwesigaba ngokobude bobude. yokukhanya okumodulithiweyo. Oko kukuthi, ixesha elifunekayo ukuze ukukhanya kuhambe kubuye naphambili kumgca wophando lilinganiswa ngendlela engangqalanga. Uluhlu lwe-laser lwesigaba lusetyenziswa ngokubanzi kwibala lokuchaneka kokusukela. Ngenxa yokuchaneka kwayo okuphezulu, ngokuqhelekileyo ngokulandelelana kweemilimitha, ukwenzela ukuba kubonakaliswe ngokufanelekileyo umqondiso kunye nokunciphisa itekeni ekujoliswe kuyo kwindawo ethile ehambelana nokuchaneka kwesixhobo, esi sixhobo esijikelezayo sixhotyiswe ngomboniso obizwa ngokuba yinjongo yokubambisana. ipleyiti.

Uluhlu lwe-laser yesigaba luhlala lufanelekile kumlinganiselo omfutshane kunye nophakathi, kwaye ukuchaneka komlinganiselo kunokufikelela kwiimilimitha. Ikwayindlela enomgangatho ophezulu wokuchaneka okwangoku. Inqanaba lokulinganisa kukulungelelanisa ukukhanya kokukhanya okukhutshiweyo kunye nomqondiso ohlengahlengisiweyo, kunye nokulinganisa ngokungathanga ngqo ixesha ngokulinganisa umahluko wesigaba, obunzima kakhulu kunokulinganisa ngokuthe ngqo ixesha lokuya nokubuya.

Ukuba ufuna ukwazi ngakumbi ulwazi lobugcisa kunye neemveliso ezinxulumene ne-laser range, nceda uqhagamshelane nathi.
