Bafuputsi ba Univesithi ea Michigan le Univesithi ea Osaka mokhoa o mocha oa tlhaselo , e u lumellang ho etsisa litaelo tsa lentsoe u le hole u sebelisa laser bakeng sa lisebelisoa tse tšehetsang taolo ea lentsoe, joalo ka libui tse bohlale, matlapa, li-smartphone le lisebelisoa tse bohlale tsa taolo ea lapeng u sebelisa Google Assistant, Amazon Alexa, Facebook Portal le Apple Siri. Nakong ea liteko, ho ile ha bontšoa tlhaselo e entseng hore ho khonehe ho kenya taelo ea lentsoe sebakeng sa sebaka sa limithara tse 75 ka khalase ea fensetere le limithara tse 110 sebakeng se bulehileng.
Tlhaselo e itšetlehile ka tšebeliso , eo ho eona ho kenngoa ha leseli (modulated) ka thepa ho lebisa ho tsosoloso ea mocheso oa seaplane, phetoho ea bongata ba thepa le ponahalo ea maqhubu a molumo a lemohuoang ke lera la microphone. Ka ho fetola matla a laser le ho tsepamisa sekoting se ka sekoting se nang le maekrofono, o ka fihlela ts'usumetso ea melumo ea molumo e ke keng ea utloahala ho ba bang, empa e tla lemohuoa ke maekrofono.
Tlhaselo e ama li-microphone tsa electromechanical tse sebelisoang lisebelisoa tsa morao-rao ().
Har'a lisebelisoa tsa bareki tse lekiloeng bakeng sa ho ba le bothata bona ke mefuta e fapaneng ea Lehae la Google, Google NEST, Amazon Echo, Echo Plus/Spot/Dot, Facebook Portal Mini, Fire Cube TV, EchoBee 4, iPhone XR, iPad 6th Gen, Samsung Galaxy. S9 le Google Pixel 2, hape le linotlolo tse bohlale le litsamaiso tsa taolo ea lentsoe bakeng sa likoloi tsa Tesla le Ford. U sebelisa mokhoa o reriloeng oa tlhaselo, u ka etsisa ho fana ka taelo ea ho bula lemati la karache, ho reka ka marang-rang, ho leka ho hakanya PIN khoutu bakeng sa ho fihlella senotlolo se bohlale, kapa ho qala koloi e tšehetsang taolo ea lentsoe.
Maemong a mangata, matla a laser a 50 mW a lekane ho etsa tlhaselo sebakeng se fetang 60. Ho phethahatsa tlhaselo, ho ile ha sebelisoa laser pointer ea $14, Wavelength Electronics LD18CHA ea $5, amplifier ea audio ea Neoteck NTK339 ea $059, le lense ea mohala ea Opteka 28-650mm ea $1300. E le ho tsepamisa mohopolo ka nepo sehatsetsing se le hole haholo le sesebelisoa, baetsi ba liteko ba ile ba sebelisa sebonela-hōle e le pono ea mahlo. Libakeng tse haufi, ho e-na le laser, mohloli o khanyang o sa tsejoeng, joalo ka .
Hangata tlhaselo ha e hloke papiso ea lentsoe la mong'a eona, kaha temoso ea lentsoe hangata e sebelisoa nakong ea ho fihlella sesebelisoa (ho netefatsa ka ho bitsa "OK Google" kapa "Alexa", e ka rekotiloeng esale pele ebe e sebelisoa ho fetola. sesupo nakong ya tlhaselo). Litšobotsi tsa lentsoe le tsona li ka etsoa ke lisebelisoa tsa sejoale-joale tsa ho ithuta ka mochini. E le ho thibela tlhaselo, bahlahisi ba khothalletsoa ho sebelisa mechine e eketsehileng ea ho netefatsa basebelisi, ho sebelisa lintlha tse tsoang ho li-microphone tse peli, kapa ho kenya mokoallo ka pel'a microphone e thibelang tsela e tobileng ea leseli.
