Kev siv tshuab optical, x-ray sorting nrhiav tau cov khoom tsis xav tau

Cov teb thiab cov vaj txiv hmab txiv ntoo tuaj yeem yog lub ntiaj teb zoo kawg nkaus, muaj khawv koob rau lawv tus kheej.

Koj tsuas yog tsis xav kom lawv cov neeg nyob hauv - lossis cov neeg tawm tsam - xaus rau hauv koj lub zaub xas lav lossis lub hnab txiv pos nphuab khov. Cov neeg siv khoom kuj tsis pom cov nplooj qhuav, qhuav lossis cov txiv pos nphuab xim av uas qab heev.

Qhov ntawd yog qhov uas kev txheeb xyuas thiab kev siv tshuab x-ray/kev kuaj hlau los pab. Txawm yog siv lub tshuab ua khoom tshiab, khov lossis ntim rau hauv lub thawv, cov khoom noj los ntawm tib qho chaw: sab nraum zoov. Cov qav, nab, kab, cov khoom txawv teb chaws xws li hlau, cov khoom tsis zoo - txhua yam yuav tsum tau txheeb xyuas thiab tshem tawm kom zoo tshaj plaws thaum lub sijhawm ntawd. ua.

Thiab lub peev xwm rau cov neeg tawm tsam tsis xaus thaum cov khoom noj mus txog rau hauv cov nroj tsuag. Txawm hais tias feem ntau muaj cov khoom tiv thaiv thiab ntau yam kev tiv thaiv, cov khoom kuj tuaj yeem nkag mus rau hauv qhov ntawd thiab.

"Hauv kev lag luam, cov tuam txhab feem ntau sib txawv ntawm kev siv tshuab cais thiab kev kuaj x-ray / hlau," Richard F. Stier, tus kws tshawb fawb txog zaub mov hauv Sonoma, California hais. "Cov thev naus laus zis tom kawg yog tsim los tshem tawm cov khoom txawv teb chaws tshwj xeeb."

Stier hais tias, cov tshuab nrhiav hlau thiab cov tshuab x-ray tuaj yeem txheeb xyuas cov hlau, pob zeb, pob txha tawv, yas thiab lwm yam khoom siv raws li qhov sib txawv ntawm qhov ceev. Nws hais tias lawv yog cov tsiaj txawv ntawm cov thev naus laus zis cais, uas siv cov lasers thiab cov teeb pom kev sib txawv.

Kev cais tawm: Li cas thiab thaum twg

John Kadinger, Key Technology Tus thawj tswj kev lag luam nyob hauv Walla Walla, Washington, tau hais tias ntxiv rau kev cais cov khoom siv siv cov koob yees duab xim nrog cov kev xaiv txheem thiab infrared uas tuaj yeem khaws qhov sib txawv ntawm cov xim thiab cov qauv kom paub qhov txawv ntawm cov khoom zoo thiab txhua yam, cov tshuab laser zoo thaum tshuaj xyuas cov khoom thaum nkag mus rau hauv cov nroj tsuag - ntawm lawv tus kheej lossis ua ke nrog cov koob yees duab, nyob ntawm daim ntawv thov. Lub tshuab fluorescence-sensing laser sorter txheeb xyuas cov qib sib txawv ntawm chlorophyll nrog rau xim, qhov loj me thiab cov duab kom qhia qhov zoo los ntawm qhov tsis zoo.

Kadinger hais tias kev kuaj pom hlau feem ntau yog qhov kev kuaj zaum kawg rau cov khoom siv hlau txawv teb chaws hauv cov pob khoom tiag tiag.

"Kev cais cov khoom siv digital, ntawm qhov tod tes, tuaj yeem ua tau ntau qhov chaw hauv kab," nws hais. "Qhov sib txawv tseem ceeb yog kev cais cov khoom siv digital siv ntau hom sensor los txheeb xyuas cov khoom txawv teb chaws thiab cov qhov tsis zoo siv ntau yam ntxwv ... xim, duab, qhov loj me, cov qauv thiab cov khoom siv biochemical."

Nws hais tias kev siv cov cuab yeej nrhiav hlau thaum lub ntim khoom tiav lawm yam tsis tau kuaj ua ntej yuav ua rau pov tseg. Yog tias pom cov khoom txawv teb chaws, tag nrho cov pob khoom yuav raug tshem tawm, Kadinger hais. Cov tuam txhab uas tshuaj xyuas cov khoom ua ntej yuav ua tau zoo dua thiab pom cov khib nyiab tsawg dua, nws hais.

"Peb tab tom ua kev cais ntau ntawm qhov kawg tau txais lossis kev cais ua ntej ntim lossis txhua qhov chaw nyob nruab nrab, nyob ntawm qhov kev teeb tsa ntawm lub Hoobkas," nws hais. "Peb tab tom nrhiav cov khoom txawv teb chaws thiab cov qhov tsis zoo thaum nws nkag mus rau hauv lub Hoobkas. Tom qab ntawd hauv cov txheej txheem, nws tsom mus rau qhov tsis zoo, tab sis cov khoom txawv teb chaws kuj tseem ceeb. Qhov twg lub tshuab cais nyob ntawm lub tswv yim ntawm lub Hoobkas."

Qee qhov kev ua haujlwm siv ntau lub tshuab sorting ua ntej hauv cov txheej txheem kom ntseeg tau tias feem ntau ntawm cov khoom txawv teb chaws tsis xav tau thiab cov khoom tsis zoo raug tshem tawm sai dua li tom qab - txoj kev cai uas Kadinger pom zoo.

"Yav tas los, ua txhua yam kev ua tiav ua ntej, tom qab ntawd cais thiab ua qhov kev kuaj xyuas zoo ua ntej ntim khoom," Kadinger hais. "Tab sis tam sim no qee tus pom tias nws txhim kho cov txheej txheem los ntawm kev cais ua ntej."

Qhov ntawd yuav ua tau zoo dua vim tias "lawv tsis ua cov khoom uas lawv yuav tsis muag," Kadinger hais. "Nws yooj yim dua los tshem tawm cov qhov tsis zoo sai dua, tsuas yog ua cov khoom zoo xwb."

Nws hais ntxiv tias qee yam khoom "zoo" uas raug tshem tawm nrog cov khoom phem hauv kev tshuaj ntsuam thaum ntxov tuaj yeem muab tso rau hauv kev xaiv thib ob thiab rov qab tau.

"Peb ntseeg tias nws yog qhov zoo tshaj plaws los txheeb xyuas kom koj cov qoob loo zoo dua thiab ua haujlwm tau zoo sai li sai tau," nws hais, "thiab tseem yuav tsum xyuas kom meej tias thaum kawg tsis muaj dab tsi tau nkag mus rau hauv cov kwj dej xws li cov ntsaws pob ntseg, hnab looj tes lossis ib yam dab tsi siv hauv cov nroj tsuag. Peb txoj haujlwm yog (txheeb xyuas) ob qho kawg."

Tau kawg, cov khoom muag muaj ntau yam ua rau cov txheej txheem no.

"Feem ntau rau kev siv tshiab peb pom zoo kom siv lub koob yees duab thiab laser sensors rau ob qho tib si thaum ntxov lossis tom qab hauv cov txheej txheem," Kadinger hais, hais txog spinach nrog nws qhov kev nyiam los nrog ntau cov khib nyiab hauv thaj teb ua piv txwv ntawm kev siv cov thev naus laus zis ua ke.

Hauv cov txiv ntoo qhuav thiab cov txiv hmab qhuav, Kadinger hais tias Key tau sim siv cov koob yees duab uas siv "hyper-spectral color spectrum" los pab sib txawv ntawm qhov sib txawv me me hauv cov xim. Piv txwv li, lub plhaub, lub plhaub thiab cov membranes hauv walnuts thiab almonds muaj xim zoo sib xws heev, ua rau nws nyuaj rau paub qhov txawv ntawm qhov yog dab tsi.
