Mune optical masisitimu akadai se laser inotangira, LiDAR, uye kuzivikanwa kwechinangwa, Er: Girazi laser transmitters anoshandiswa zvakanyanya mune zvese zvechiuto uye zvechivanhu zvikumbiro nekuda kwekuchengetedzeka kwemeso uye kuvimbika kwakanyanya. Pamusoro pesimba rekupuruzira, chiyero chekudzokorora (frequency) ndiyo yakakosha parameter yekuongorora mashandiro. Inokanganisa laser's yekupindura kumhanya, data acquisition density, uye ine hukama zvakanyanya nekutonga kwekupisa, dhizaini yekugovera magetsi, uye kugadzikana kwehurongwa.
1. Chii chinonzi Frequency yeLaser?
Laser frequency inoreva huwandu hwemapulses anoburitswa pachikamu chenguva, chinowanzoyerwa mu hertz (Hz) kana kilohertz (kHz). Iyo inozivikanwawo seyedzo yekudzokorodza, ndiyo yakakosha kuita chiratidzo kune pulsed lasers.
Semuenzaniso: 1 Hz = 1 laser pulse pasekondi, 10 kHz = 10,000 laser pulses pasekondi. Yakawanda Er:Glass lasers inoshanda mu pulsed mode, uye frequency yavo yakabatana zvakanyanya neinobuda waveform, system sampling, uye chinangwa echo kugadzirisa.
2. Common Frequency Range yeEr:Glass Lasers
Zvichienderana ne laser's dhizaini yedhizaini uye zvinodiwa zvekushandisa, Er: Girazi laser transmitters inogona kushanda kubva kune imwechete-kupfura modhi (yakadzika se1 Hz) kusvika makumi emakumi ekirohertz (kHz). Yepamusoro mafrequency anotsigira kukurumidza kutarisisa, kuenderera mberi kwekutevera, uye kuomarara kwekutora data, asi ivo zvakare vanoisa zvichemo zvakakwirira pakushandiswa kwesimba, kutonga kwekupisa, uye laser lifetime.
3. Zvinhu Zvikuru Zvinokanganisa Kudzokorora Mwero
①Pump Source uye Power Supply Design
Laser diode (LD) pombi masosi anofanira kutsigira yakakwirira-kumhanya modulation uye kupa simba rakagadzikana. Mamodule emagetsi anofanirwa kuve anopindura zvakanyanya uye anobudirira kubata kazhinji pa/kudzima ma cycles.
②Thermal Management
Iyo yakakwirira iyo frequency, iyo yakanyanya kupisa inogadzirwa panguva yeyuniti. Madhishi ekupisa anoshanda zvakanaka, TEC tembiricha yekudzora, kana microchannel yekutonhodza zvimiro zvinobatsira kuchengetedza zvakatsiga kubuda uye kuwedzera hupenyu hwesevhisi yechishandiso.
③Q-Switching Method
Passive Q-switching (semuenzaniso, kushandisa Cr: YAG makristasi) kazhinji akakodzera kune yakaderera-frequency lasers, nepo inoshanda Q-switching (semuenzaniso, ine acousto-optic kana electro-optic modulators sePockels masero) inogonesa yakakwirira frequency mashandiro ane programmable control.
④Module Dhizaini
Compact, simba-inoshanda laser musoro dhizaini inovimbisa kuti pulse simba rinochengetwa kunyangwe pakakwirira frequency.
4. Frequency uye Application Matching Recommendations
Mamiriro ekushandisa akasiyana anoda ma frequency ekushanda akasiyana. Kusarudza mwero wekudzokorora wakakodzera kwakakosha kuti uve nechokwadi chekuita kwakaringana. Pazasi pane mamwe akajairika makesi ekushandisa uye kurudziro:
①Yakaderera Frequency, Yakakwira Simba Modhi (1-20 Hz)
Yakanakira kureba-renji laser kubva uye chinangwa chezita, uko kupinza uye kugadzikana kwesimba kwakakosha.
②Yepakati Frequency, Medium Energy Modhi (50-500Hz)
Inokodzera maindasitiri emhando, kufamba, uye masisitimu ane mwero frequency zvinodiwa.
③High Frequency, Low Energy Mode (>1 kHz)
Yakanyatsokodzera LiDAR masisitimu anosanganisira array scanning, point Cloud generation, uye 3D modelling.
5. Tekinoroji Trends
Sezvo kubatanidzwa kwelaser kuri kuramba kuchienderera mberi, chizvarwa chinotevera cheEr:Glass laser transmitters chiri kushanduka nenzira dzinotevera:
①Kubatanidza mareti ekudzokorora akakwirira nekubuda kwakagadzikana
②Intelligent kutyaira uye dynamic frequency control
③Yakareruka uye yakaderera-simba rekushandisa dhizaini
④Dual-control architectures ezvese frequency uye simba, inogonesa inoshanduka modhi switch (semuenzaniso, scanning / kutarisa / kuteedzera)
6. Mhedziso
Kushanda frequency ndiyo yakakosha parameter mukugadzira uye kusarudzwa kweEr: Girazi laser transmitters. Iyo inongotarisa kwete chete kugona kwekutora data uye sisitimu mhinduro asi zvakare inokanganisa zvakananga kudziya kwekutonga uye laser lifespan. Kune vanogadzira, kunzwisisa chiyero pakati pe frequency ne simba-uye kusarudza ma parameter anoenderana nechaiyo application-chinhu chakakosha pakugadzirisa mashandiro ehurongwa.
Inzwa wakasununguka kutibata kuti udzidze zvakawanda nezve yedu yakakura yeEr: Girazi laser transmitter zvigadzirwa zvine ma frequency akasiyana uye zvakatemwa. Isu're pano kuti ikubatsire kusangana nezvido zvako zvehunyanzvi mukubvakacha, LiDAR, kufamba, uye kudzivirira maapplication.
