Kuwunika kwa Mitundu Yoyikira Laser: Mfundo Zaukadaulo ndi Kugwiritsa Ntchito Kwanthawi Zobwerezabwereza Zobwerezabwereza, Code Variable Pulse Interval Code, ndi Code PCM

Pamene ukadaulo wa laser ukuchulukirachulukira m'magawo monga kuyambira, kulumikizana, kuyenda, ndi kuzindikira kutali, njira zosinthira ndi ma encoding azizindikiro za laser zakhalanso zosiyanasiyana komanso zapamwamba. Pofuna kukulitsa luso lothana ndi kusokoneza, kulondola kosiyanasiyana, komanso kutumizirana ma data, mainjiniya apanga njira zingapo zolembera, kuphatikiza Precision Repetition Frequency (PRF) Code, Variable Pulse Interval Code, ndi Pulse Code Modulation (PCM).

Nkhaniyi ikuwunikira mozama mitundu yamtundu wa laser encoding iyi kuti ikuthandizeni kumvetsetsa mfundo zake zogwirira ntchito, mawonekedwe aukadaulo, komanso momwe amagwiritsira ntchito.

1. Khodi Yobwerezabwereza Molondola (PRF Code)

①Mfundo Zaumisiri
Khodi ya PRF ndi njira yolumikizira yomwe imatumiza ma pulse pafupipafupi pafupipafupi (mwachitsanzo, 10 kHz, 20 kHz). M'machitidwe opangira laser, kugunda kulikonse komwe kumabwerera kumasiyanitsidwa kutengera ma frequency ake otulutsa, omwe amayendetsedwa mwamphamvu ndi dongosolo.

②Zofunika Kwambiri

Kapangidwe kosavuta komanso mtengo wotsika wokhazikitsa

Zoyenera kuyeza zazifupi komanso zowunikira kwambiri

Zosavuta kugwirizanitsa ndi machitidwe a wotchi apakompyuta

Zosagwira ntchito bwino m'malo ovuta kapena zochitika zambiri zomwe mukufuna kuchita chifukwa cha chiopsezo cha“echo yamtengo wapatali”kusokoneza

③Zochitika za Ntchito
Ma laser rangefinders, zida zoyezera mtunda umodzi zomwe mukufuna, makina owunikira mafakitale

2. Code Variable Pulse Interval Code (Mwachisawawa kapena Variable Pulse Interval Code)

①Mfundo Zaumisiri
Njira yotsekera iyi imawongolera nthawi pakati pa kugunda kwa laser kuti kukhale kwachisawawa kapena mongoyerekeza (mwachitsanzo, kugwiritsa ntchito jenereta yotsatizana mwachisawawa), m'malo mokhazikika. Kusasinthika kumeneku kumathandiza kusiyanitsa zizindikiro zobwerera ndikuchepetsa kusokoneza kwa njira zambiri.

②Zofunika Kwambiri

Kuthekera kwamphamvu kotsutsana ndi kusokoneza, koyenera kuzindikira chandamale m'malo ovuta

Imapondereza bwino mamvekedwe a mizimu

Kuvuta kwa ma decoding apamwamba, kumafunikira mapurosesa amphamvu kwambiri

Zoyenera kulondola kwambiri komanso kuzindikira zandalama zambiri

③Zochitika za Ntchito
Machitidwe a LiDAR, njira zowunikira za UAV / chitetezo, ma laser ankhondo ndi njira zozindikiritsira chandamale

3. Pulse Code Modulation (PCM Code)

①Mfundo Zaumisiri
PCM ndi njira yosinthira digito pomwe ma siginecha a analogi amatsatiridwa, kuchulukidwa, ndikuyikidwa mu mawonekedwe a binary. M'makina olankhulirana a laser, data ya PCM imatha kunyamulidwa kudzera pa ma laser pulses kuti ikwaniritse kufalitsa chidziwitso.

②Zofunika Kwambiri

Kutumiza kokhazikika komanso kukana kwamphamvu kwaphokoso

Itha kufalitsa zidziwitso zosiyanasiyana, kuphatikiza ma audio, malamulo, ndi ma data

Pamafunika kulunzanitsa wotchi kuonetsetsa decoding yoyenera pa wolandira

Imafunikira ma modulator ochita bwino kwambiri ndi ma demodulators

③Zochitika za Ntchito
Malo olumikizirana ndi ma laser (mwachitsanzo, Free Space Optical communication systems), laser remote control ya mizinga/spacecraft, kubweza deta mu makina a laser telemetry

4. Mapeto

Monga“ubongo”ya machitidwe a laser, ukadaulo wa laser encoding umatsimikizira momwe chidziwitso chimafalidwira komanso momwe dongosololi limagwirira ntchito. Kuchokera pamakhodi oyambira a PRF mpaka kusinthika kwapakatikati kwa PCM, kusankha ndi kamangidwe ka ma encoding schemes kwakhala kiyi pakuwongolera magwiridwe antchito a laser system.

Kusankha njira yoyenera yolembera kumafuna kulingalira mozama za momwe ntchito ikugwiritsidwira ntchito, milingo yosokoneza, kuchuluka kwa zomwe mukufuna, komanso kugwiritsa ntchito mphamvu zamagetsi. Mwachitsanzo, ngati cholinga chake ndikumanga dongosolo la LiDAR lachitsanzo cha 3D chakumatauni, kachidindo kosiyana kosiyanasiyana kokhala ndi mphamvu yolimbana ndi jamming ndiyofunika. Pazida zosavuta zoyezera mtunda, kachidindo kobwerezabwereza kolondola kokwanira kangakhale kokwanira.
