2. Lambobin tazarar bugun jini mai canzawa (Lambar bazuwar ko Maɓallin tazarar bugun jini)

①Ƙa'idar Fasaha
Wannan hanyar ɓoyewa tana sarrafa tazarar lokaci tsakanin bugun laser don zama bazuwar ko bazuwar-bazuwar (misali, ta amfani da janareta na bazuwar bazuwar), maimakon gyarawa. Wannan bazuwar yana taimakawa bambance siginonin dawowa da rage tsangwama ta hanyoyi da yawa.

②Mabuɗin Siffofin

Ƙarfin ƙarfin hana tsangwama, manufa don gano manufa a cikin mahalli masu rikitarwa

Yadda ya kamata yana danne fatalwa

Ya dace da babban madaidaicin jeri da gano manufa da yawa

③Yanayin aikace-aikace
Tsarin LiDAR, counter-UAV/tsarin sa ido na tsaro, kewayon Laser na soja da tsarin gano manufa

3. Ƙididdigar lambar bugun jini (Lambar PCM)

①Ƙa'idar Fasaha
PCM dabara ce ta daidaitawa ta dijital inda ake ƙididdige siginar analog, ƙididdigewa, da sanya su cikin nau'i na binary. A cikin tsarin sadarwar Laser, ana iya ɗaukar bayanan PCM ta hanyar bugun laser don cimma nasarar watsa bayanai.

②Mabuɗin Siffofin

Tsayayyen watsawa da juriya mai ƙarfi

Mai ikon watsa nau'ikan bayanai daban-daban, gami da sauti, umarni, da bayanan matsayi

4. Kammalawa

Kamar yadda"kwakwalwa”na tsarin laser, fasahar ɓoye bayanan laser yana ƙayyade yadda ake watsa bayanai da kuma yadda tsarin ke aiki da kyau. Daga ainihin lambobin PRF zuwa na'urorin PCM na ci gaba, zaɓi da ƙirar tsare-tsaren ɓoyewa sun zama mabuɗin don haɓaka aikin tsarin laser.

Zaɓin hanyar da ta dace ta ɓoye yana buƙatar cikakken la'akari da yanayin aikace-aikacen, matakan tsangwama, adadin maƙasudai, da tsarin amfani da wutar lantarki. Misali, idan makasudin shine gina tsarin LiDAR don ƙirar ƙirar 3D na birni, an fi son lambar tazarar bugun bugun jini mai ƙarfi tare da ƙarfin hana jamming. Don sauƙin kayan auna nisa, madaidaicin lambar mitar na iya isa.
