Isi ihe dị na nso nso a bụ ebe dị anya nke foton ndị laser na-ebupụta nwere ike imeri nhụsianya ikuku na nhụsianya ebumnuche, ma ka na-ejide ya site na njedebe nnata dị ka akara ngosi dị irè. Ihe ngosi ndị a nke isi iyi laser 1.5 μm fiber laser na-achịkwa usoro a ozugbo:
① Ike kacha elu (kW): ọkọlọtọ 3kW @ 3ns & 100kHz ； Ngwaahịa emelitere 8kW @ 3ns & 100kHz bụ "ike ịnya ụgbọ ala" nke oke nchọta, na-anọchi anya ike ozugbo nke laser wepụtara n'ime otu usu, na ọ bụ isi ihe na-ekpebi ike nke akara ngosi dị anya. Na nchọpụta drone, photons kwesịrị ịga ọtụtụ narị ma ọ bụ ọbụna ọtụtụ puku mita site na ikuku, nke nwere ike ime ka attenuation n'ihi mgbasa nke Rayleigh na aerosol absorption (ọ bụ ezie na 1.5 μm band bụ nke "window ikuku", a ka nwere attenuation attenuation). N'otu oge ahụ, nlegharị anya elu ezubere iche (dịka ọdịiche dị na ahịhịa, ọla, na okwute) nwekwara ike ibute mfu mgbaàmà. Mgbe ike kacha elu na-abawanye, ọbụna mgbe ogologo anya attenuation na echiche ọnwụ, ọnụ ọgụgụ nke photons na-eru na njedebe na-anata ka nwere ike izute "signal-na-noise ratio threshold", si otú ịgbatị ihe nchọpụta nso - dịka ọmụmaatụ, site n'ịbawanye ike kachasị elu nke 1.5 μm fiber laser site na 1kW ruo 5kW, n'okpuru ọnọdụ nke 1. gbatịpụrụ site na mita 200 ruo mita 350, na-edozi kpọmkwem ihe mgbu nke "enweghị ike ịlele anya" na ọnọdụ nyocha buru ibu dị ka ugwu ugwu na ọzara maka drones.
② Obosara usu (ns): mgbanwe site na 1 ruo 10ns. Ọkọlọtọ ngwaahịa nwere a zuru okpomọkụ (-40 ~ 85 ℃) usu obosara okpomọkụ mbanye nke ≤ 0.5ns; n'ihu, ọ nwere ike iru a zuru okpomọkụ (-40 ~ 85 ℃) usu obosara okpomọkụ mbanye nke ≤ 0.2ns. Ihe ngosi a bụ "ọnụọgụ oge" nke ziri ezi nke anya, na-anọchi anya ogologo oge nke pulses laser. Usoro ngụkọ anya maka nchọpụta drone bụ "anya = (ọkụ ọkụ x pulse oge njem njem)/2", yabụ obosara usu na-ekpebi ozugbo "ntụzi nha oge". Mgbe obosara pulse na-ebelata, "oge nkọ" nke pulse na-abawanye, na njehie oge n'etiti "oge pulse emission" na "oge nnabata pulse gosipụtara" na njedebe nnata ga-ebelata nke ukwuu.
③ Nkwụsi ike nke ogologo: n'ime 1pm / ℃, obosara ahịrị na okpomọkụ zuru oke nke 0.128nm bụ "arịlịka ziri ezi" n'okpuru nnyonye anya gburugburu ebe obibi, yana mgbanwe mgbanwe nke laser mmepụta wavelength na okpomọkụ na voltaji mgbanwe. Usoro nchọpụta na 1.5 μm wavelength band na-ejikarị teknụzụ "wavelength diversity reception" ma ọ bụ "interferometry" nkà na ụzụ iji meziwanye izi ezi, na ngbanwe ogologo ogologo nwere ike ime ka nha nha nha anya - dịka ọmụmaatụ, mgbe drone na-arụ ọrụ na elu elu, ọnọdụ okpomọkụ nwere ike ibili site na -10 ℃ 3.0. Ọ bụrụ na ọnụọgụ okpomọkụ nke 1.5 μm fiber laser bụ 5pm / ℃, ogologo wavelength ga-agbanwe site na 200pm, na njehie nha anya kwekọrọ ga-abawanye site na 0.3 millimeters (nke sitere na usoro mmekọrịta n'etiti ogologo wavelength na ọsọ ọkụ). Karịsịa n'ebe ndị na-ahụ maka ikuku ụgbọ ala na-enweghị mmadụ, ọ dị mkpa ka a tụọ ihe ndị dị ka sag waya na ogologo ahịrị. Ogologo ebili mmiri na-adịghị akwụ ụgwọ nwere ike iduga ngbanwe data ma na-emetụta ntule nchekwa ahịrị; Laser 1.5 μm na-eji teknụzụ mkpọchi ogologo ogologo nwere ike ijikwa nkwụsi ike ogologo oge n'ime 1pm / ℃, na-ahụta izi ezi nke ọkwa centimita ọbụlagodi mgbe mgbanwe okpomọkụ na-eme.
④ Mmekọrịta ihe ngosi: "Ntụziaka" n'etiti izi ezi na oke na ọnọdụ nchọpụta drone n'ezie, ebe ndị na-egosi adịghị eme onwe ha, kama nwee mmekorita ma ọ bụ mmachi. Dị ka ihe atụ, na-amụba elu ike nwere ike ịgbatị na nchọpụta nso, ma ọ dị mkpa ijikwa pulse obosara iji zere mbelata nke ziri ezi (a itule nke "elu ike + warara pulse" kwesịrị inweta site pulse mkpakọ technology); Ịkwalite ogo beam nwere ike imeziwanye oke na izi ezi n'otu oge (ịta ahụhụ n'okirikiri na-ebelata mkpofu ume yana nnyonye anya nha na-ebute site na ntupọ ọkụ na-agafe n'ebe dị anya). Uru nke laser fiber 1.5 μm dabere n'ikike ya iji nweta njikarịcha synergistic nke "ike elu dị elu (1-10 kW), obosara usu dị warara (1-10 ns), ogo beam dị elu (M ² <1.5), na nkwụsi ike dị elu (<1pm / ℃)" site na njirimara dị ala nke mgbasa ozi fiber na pulse. Nke a na-enweta ọganihu abụọ nke "ogologo dị anya (300-500 mita)+ nkenke dị elu (ọkwa centimeter)" na nchọpụta ụgbọ ala na-adịghị mma, nke bụkwa isi asọmpi ya n'iji dochie 905nm omenala na 1064nm lasers na nyocha ụgbọ elu na-enweghị isi, nnapụta mberede na ọnọdụ ndị ọzọ.
