Koox cilmi-baarayaal ah oo ka socda Jaamacadda Ben-Gurion ee Negev iyo Machadka Weizmann ee Sayniska (Israel) ayaa sameeyay farsamo () in dib loo dhiso wada sheekeysiga gudaha iyo muusiga iyadoo la isticmaalayo falanqeynta gariir dadban ee nalka iftiinka ee ku jira qalabka nalka. Dareemaha korantada-optical-ka ee lagu dhejiyay waddada ayaa loo adeegsaday falanqeeye ahaan, iyadoo la isticmaalayo telescope, waxaa loola dan lahaa laambad ka muuqata daaqadda. Tijaabadan ayaa waxaa lagu sameeyay Laambado 12-watt ah oo LED ah, waxaana suuragashay in la abaabulo dhageysiga meel fog oo dhan 25 mitir.
Habkani wuxuu u shaqeeyaa laambad hakad ah. Gariirada dhawaaqa waxay abuuraan kala duwanaansho cadaadiska hawada, kaas oo keena microvibration shay laalan. microvibrations noocan oo kale ah waxay keenaysaa in iftiinka xagal kala duwan ay sabab u tahay barakaca diyaaradda ee dhalaalka, kaas oo lagu ogaan karaa iyadoo la isticmaalayo shidma electro-optical xasaasi ah iyo demodulated galay dhawaaqa. Telescope ayaa loo adeegsaday in lagu qabto socodka iftiinka oo loogu jiheeyo dareenka. Calaamadda laga helay dareemayaasha (Thorlabs PDA100A2 oo ku salaysan sawir-qaadaha) ayaa loo beddelay qaab dhijitaal ah iyadoo la adeegsanayo beddelaha 16-bit analog-to-dijital ADC NI-9223.
Kala soocida macluumaadka la xidhiidha dhawaaqa ee calaamadda guud ee indhaha ayaa la fuliyay dhowr marxaladood, oo ay ku jiraan , Caadiyan, dhimista qaylada iyo sixitaanka baaxadda inta jeer. Qoraal MATLAB ah ayaa la diyaariyey si loo habeeyo calaamadaha. Tayada soo celinta dhawaaqa marka laga soo qaadayo cabirrada fogaanta mitirka 25 waxay noqotay mid ku filan aqoonsiga hadalka iyada oo loo marayo Google Cloud Speech API iyo go'aaminta halabuurka muusiga iyada oo loo marayo adeegyada Shazam iyo SoundHound.
Tijaabada, codka ayaa lagu soo saaray qolka ugu badnaan codadka la heli karo, i.e. dhawaqa ayaa aad uga xoog badnaa hadalka caadiga ah. Nalalka LED-ka sidoo kale laguma dooran si kadis ah, laakiin sida bixinta saamiga ugu sarreeya ee signal-ilaa-sanqa (6.3 jeer ka sarreeya nalka iftiinka iyo 70 jeer ka sarreeya nalka fluorescent). Cilmi-baadhayaashu waxay sharraxeen in baaxadda weerarka iyo dareenka la kordhin karo iyadoo la adeegsanayo telescope weyn, dareeme tayo sare leh, iyo 24-ama 32-bit analog-to-digital Converter (ADC); tijaabada waxaa la sameeyay iyadoo la adeegsanayo telescope-gacan, Dareem raqiis ah, iyo 16-bit ADC.
Si ka duwan qaabkii hore loo soo jeediyay""Lamphone-ka oo soo qabata oo falanqeeya walxaha gariiraya qolka dhexdiisa, sida koob biyo ah ama xirmo jajab ah, Lamphone wuxuu suurtogal ka dhigayaa in la habeeyo dhegeysiga wakhtiga dhabta ah, halka makarafoonka muuqaalka ah si dib loogu dhiso dhowr ilbiriqsi oo hadal ah ayaa u baahan xisaabin degdeg ah oo qaadata. saacadaha . Si ka duwan hababka ku salaysan isticmaalka ama Makarafoon ahaan, Lamphone-ku waxa uu ogolaadaa in weerarka meel fog laga fuliyo, iyada oo aan loo baahnayn in lagu socodsiiyo aaladaha dhismaha dhexdiisa. Si ka duwan weerarrada la isticmaalayo , Lamphone uma baahna iftiiminta shayga gariiraya waxaana lagu soo saari karaa qaab dadban.
