Mumasystem e optical akadai se laser ranging, LiDAR, uye target recognition, Er:Glass laser transmitters inoshandiswa zvakanyanya mukushandiswa kwemauto neveruzhinji nekuda kwekuchengetedzwa kwemaziso avo uye kuvimbika kwakanyanya. Kuwedzera kune simba rekurova kwemoyo, repetition rate (frequency) chinhu chakakosha pakuongorora mashandiro. Inokanganisa laser.'kumhanya kwekupindura, kuwanda kwedata, uye zvine chekuita nekutarisira kupisa, dhizaini yemagetsi, uye kugadzikana kwesystem.
1. Chii Chinonzi Kuwanda KweLaser?
Kuwanda kweLaser kunoreva huwandu hwemapulse anoburitswa pachikamu chenguva, anowanzo kuyerwa mu hertz (Hz) kana kilohertz (kHz). Inozivikanwawo se repetition rate, chiratidzo chikuru chekushanda kwemapulsed lasers.
Semuenzaniso: 1 Hz = 1 laser pulse pasekondi, 10 kHz = 10,000 laser pulses pasekondi. Mazhinji eEr:Glass lasers anoshanda mu pulsed mode, uye frequency yawo yakabatana zvakanyanya ne output waveform, system sampling, uye target echo processing.
2. Huwandu Hwakajairika hweEr: Magirazi eLaser
Zvichienderana nelaser'Nekuda kwekugadzirwa kwechimiro uye zvinodiwa zvekushandisa, maEr:Glass laser transmitters anogona kushanda kubva pamodhi ye single-shot (yakaderera se1 Hz) kusvika kumakumi e kilohertz (kHz). Ma frequency akakwira anotsigira kukurumidza kuskena, kutevedza nguva dzose, uye kuwanikwa kwedata rakawanda, asi anoisawo kuda kwakanyanya pakushandiswa kwesimba, manejimendi yekupisa, uye hupenyu hwe laser.
3. Zvinhu Zvikuru Zvinokanganisa Mwero weKudzokorora
①Dhizaini yePombi uye Simba reKupa
Mapombi eLaser diode (LD) anofanira kutsigira modulation yekumhanya kwepamusoro uye kupa simba rakagadzikana. Mamodule emagetsi anofanirwa kunge achipindura zvakanyanya uye achinyatsoshanda kuti akwanise kubata ma cycles anongoerekana avhurwa/kudzimwa.
②Kutarisira Kupisa
Kana frequency yakakwira, kupisa kwakawanda kunogadzirwa panguva imwe neimwe. Ma heat sinks anoshanda zvakanaka, TEC tembiricha control, kana microchannel cooling structures zvinobatsira kuchengetedza simba remagetsi rakasimba uye kuwedzera hupenyu hwebasa remuchina.
③Nzira yekuchinja Q
Kuchinja-chinja kweQ (semuenzaniso, kushandisa makristaro eCr:YAG) kunowanzo kukodzera malaser ane frequency yakaderera, nepo active Q-switching (semuenzaniso, ine acousto-optic kana electro-optic modulators dzakadai sePockels cells) inogonesa kushanda kwema frequency akakwira nehurongwa hwehurongwa.
④Dhizaini yeModule
Magadzirirwo emisoro yelaser akamanikana uye asingashandise simba zvakanyanya anoita kuti simba rekurova kwemoyo rirambe riripo kunyangwe pamafrequency akakwira.
4. Mazano ekuenzanisa mashandisirwo enguva nenguva
Mamiriro akasiyana ekushandisa anoda mafrequency akasiyana ekushanda. Kusarudza mwero wakakodzera wekudzokorora kwakakosha pakuona kuti inoshanda zvakanaka. Heano mamwe mashandisirwo akajairika uye mazano:
①Kuwanda Kwakaderera, Simba Rakawanda (1)–20 Hz)
Yakanakira kushandisa laser rangeing uye chinangwa, uko kupinda kwayo uye kugadzikana kwesimba zviri zvakakosha.
②Kuwanda Kwenguva Dzepakati, Simba Repakati (50)–500 Hz)
Yakakodzera kushandiswa kwemaindasitiri akasiyana-siyana, kufamba-famba, uye masisitimu ane zvinodiwa zvemafrequency ari pakati nepakati.
③Kuwanda Kwakawanda, Simba Rakaderera (>1 kHz)
Zvakakodzera zvikuru masisitimu eLiDAR anosanganisira array scanning, point cloud generation, uye 3D modeling.
5. Maitiro eTekinoroji
Sezvo kubatanidzwa kwelaser kuri kuramba kuchifambira mberi, chizvarwa chinotevera cheEr:Glass laser transmitters chiri kushanduka nenzira dzinotevera:
①Kubatanidza mwero wekudzokorora wakakwira nekubuda kwakagadzikana
②Kutyaira kwakangwara uye kutonga kwakasimba kwema frequency
③Dhizaini inorema uye inoshandisa simba shoma
④Magadzirirwo maviri ekudzora ma frequency nesimba, zvichiita kuti pave nekuchinja kwemodhi inochinjika (semuenzaniso, kuongorora/kutarisa/kutevera)
6. Mhedziso
Mafambiro ekushanda ndiwo chinhu chikuru mukugadzirwa uye kusarudzwa kwemaEr:Glass laser transmitters. Haangoone chete kushanda kwedata uye mhinduro yesystem asiwo anokanganisa zvakananga manejimendi yekupisa uye hupenyu hwelaser. Kune vanogadzira, kunzwisisa chiyero pakati pemafrequency nesimba.—uye kusarudza ma parameter anokodzera application chaiyo—chinhu chakakosha pakuvandudza mashandiro ehurongwa.
Sunungukai kutibata kuti muzive zvakawanda nezvezvigadzirwa zvedu zvakasiyana-siyana zveEr:Glass laser transmitter zvine mafrequency akasiyana uye specifications.'Tiri pano kuti tikubatsirei kuzadzisa zvinodiwa nehunyanzvi hwenyu mukushandisa mafambiro emhando dzakasiyana, LiDAR, kufamba, uye kudzivirira.
