Zvishandiso zveLaser rangefinder zvave zvishandiso zvinokosha muminda yakasiyana-siyana kubva kumitambo nekuvaka kusvika kutsvagurudzo yemauto nesainzi. Zvishandiso izvi zvinoyera daro nemazvo zvikuru nekubudisa mapurose elaser uye kuongorora fungidziro yazvo. Kuti tinzwisise mashandiro azvo, zvakakosha kupatsanura zvikamu zvikuru. Muchinyorwa chino, tichaongorora zvikamu zvakakosha zveLaser rangefinder uye mabasa azvo mukupa zviyero zvakarurama.
1. Laser Diode (Emitter)
Pakati pechinhu chega chega chinonzi laser rangefinder pane laser diode, iyo inogadzira mwenje wechiedza unoshandiswa pakuyera. Inowanzo shanda mu near-infrared spectrum (semuenzaniso, 905 nm kana 1550 nm wavelengths), diode iyi inoburitsa pulses pfupi, dzakanangana dzechiedza. Kusarudzwa kwewavelength kunoenzanisa kuchengetedzeka (kuchengetedza maziso evanhu) uye kushanda mumamiriro akasiyana-siyana ezvakatipoteredza. Madiode emhando yepamusoro anovimbisa kusimba kwemwaranzi kwakafanana, zvakakosha kuti zvive nyore kuona kure.
2. Sisitimu yeOptical Lens
Sisitimu ye optical lens inoita mabasa maviri makuru:
- Collimation: Danda relaser rinoburitswa rinoderedzwa uye rinonamirwa kuita danda rakafanana kuti rideredze kupararira kwedaro.
- Kutarisa: Kuti chiedza chidzoke chiratidzike, malenzi anoisa maphoton akapararira pa detector.
Zvishandiso zvemhando yepamusoro zvinogona kusanganisira malenzi anogadziriswa kana kugona kuyera kuti zvienderane nehukuru kana daro rakasiyana.
3. Chinoongorora Mufananidzo (Chinogamuchira)
Chinoongorora chiedza (photodetector)—chinowanzova avalanche photodiode (APD) kana PIN diode—chinotora ma pulses elaser anoratidzwa. Ma APD anofarirwa kushandiswa kure nekuda kwehukuru hwawo uye kugona kwawo kuwedzera masaini asina simba. Kuti asefe chiedza chemumhepo (semuenzaniso, chiedza chezuva), mafirita e optical bandpass anosanganisirwa mu receiver, zvichiita kuti wavelength chaiyo yelaser ionekwe chete.
4. Nguva Yekufamba Nendege (ToF) Dunhu
Nguva yekubhururuka ndiyo uropi hunotarisa daro. Hunoyera nguva yekunonoka pakati pekurova kwemoyo kunobuda uye kuratidzwa kwakaonekwa. Sezvo chiedza chichifamba nekumhanya kunozivikanwa (~3×10⁸ m/s), daro racho rinoverengwa uchishandisa fomura:
Matimers ekumhanya kwakanyanya (ane resolutions mu picoseconds) akakosha pakuita ma millimeter akarurama, kunyanya mumashandisirwo ari pedyo.
5. Chikamu Chekugadzirisa Zviratidzo
Data risingawanikwe kubva ku photodetector rinogadziriswa ne microcontroller kana digital signal processor (DSP). Iyi unit inosefa ruzha, inotsiva zvinhu zvakatipoteredza (semuenzaniso, atmospheric attenuation), uye inoshandura kuyerwa kwenguva kuita kuverenga kure. Maitiro epamusoro anogonawo kubata manzwi akawanda (semuenzaniso, kusateerera mashizha kana uchitarisa hunde yemuti).
6. Kuratidzwa uye Mushandisi
Zvizhinji zvezviratidziro zverangefinder zvine LCD kana OLED kuratidza zviyero, zvinowanzowedzerwa nenzira dzakadai sekugadzirisa slope, continuous scanning, kana Bluetooth connectivity yekunyora data. Zvinoiswa nemushandisi—mabhatani, touchscreens, kana rotary dials—zvinobvumira kugadziriswa kwezvishandiso zvakati, zvakaita sekutamba gorofu, kuvhima, kana kuongorora.
7. Simba remagetsi
Bhatiri rinochajwazve (semuenzaniso, Li-ion) kana masero anoraswa anoisa simba muchishandiso. Kushanda zvakanaka kwesimba kwakakosha, kunyanya kumamodheru anobatwa nemaoko anoshandiswa panze. Mamwe ma rangefinder anoshandisa nzira dzinochengetedza simba kuti awedzere hupenyu hwebhatiri panguva yekusashanda.
8. Masisitimu eDzimba neKuisa
Imba yacho yakagadzirirwa kugara kwenguva refu uye ergonomics, kazhinji ine zvinhu zvisingapindi mvura kana kuti zvisingadhuri (IP ratings). Kuti ishandiswe nezvimwe zvishandiso (semuenzaniso, makamera, pfuti, kana madrone), sarudzo dzekuisa senge tripod sockets kana Picatinny rails dzinogona kuverengerwa.
Mashandiro Azvo Pamwe Chete
1. Laser diode inoburitsa kurova kwemoyo kunoenda kune chinangwa.
2. Sisitimu ye optical inotungamira danda uye inounganidza kupenya.
3. Chinoongorora chiedza chinotora chiratidzo chekudzoka, chakasefetwa kubva muruzha rwemhepo.
4. Chiteshi cheToF chinoverenga nguva yakapera.
5. Purosesa inoshandura nguva kuita daro uye inoratidza mhedzisiro.
Mhedziso
Kubva pakunyatsorongeka kwelaser diode yayo kusvika pakunyatsogadzirwa kwemaalgorithms ayo ekugadzirisa, chikamu chimwe nechimwe chelaser rangefinder chinoita basa rakakosha pakuona kuti zvakarurama uye zvakavimbika. Kunyangwe uri mutambi wegorofu achitarisa putt kana mainjiniya wekugadzira mapu enzvimbo, kunzwisisa zvinhu izvi kunobatsira pakusarudza chishandiso chakakodzera zvaunoda.
