Kev nyab xeeb ntawm Laser Distance Sensor

Txoj kev loj hlob sai ntawm laser technology tau coj mus rau lub technologies innovation nyob rau hauv lub teb ntawmlaser nrug sensor. Laser range sensor siv laser ua cov khoom tseem ceeb ua haujlwm. Tam sim no, lub ntsiablaser ntsuasCov ntaub ntawv ntawm kev ua lag luam yog: kev ua haujlwm wavelength ntawm 905nm thiab 1540nm semiconductor laser thiab ua haujlwm wavelength ntawm 1064nm YAG laser. Txoj cai thoob ntiaj teb ntawm kev nyab xeeb ntawm cov khoom siv laser yog dab tsi? Lub Chaw Tswj Xyuas Khoom Noj thiab Tshuaj (FDA) faib cov khoom siv laser rau hauv 6 chav kawm raws li qhov loj ntawm lawv cov khoom siv laser: ClassⅠ, Class ⅱA, ClassⅡ, ClassⅢa, ClassⅢb thiab ClassⅣ.

Class I: Tsawg tso zis tsis pom laser (lub zog tsawg dua 0.4mW) tsis pub tshaj MPE tus nqi rau ob lub qhov muag thiab tawv nqaij nyob rau hauv ib qho xwm txheej, txawm tias tom qab tsom los ntawm kev kho qhov muag. tuaj yeem ua kom muaj kev nyab xeeb ntawm kev tsim, tsis muaj kev tswj hwm tshwj xeeb. Cov ntawv thov muaj xws li laser Pointers, CD player, CD-ROM cov cuab yeej, cov cuab yeej tshawb nrhiav geological thiab kuaj ntsuas ntsuas.

Chav Kawm II: Tsawg tso zis pom laser (hwj chim 0.4mW-1mW), lub sij hawm cov tshuaj tiv thaiv ntawm qhov muag kaw yog 0.25 vib nas this, siv lub sij hawm no los xam qhov raug tsis tau tshaj MPE tus nqi. Feem ntau, lub laser qis dua 1mW yuav ua rau kiv taub hau thiab xav tsis thoob. Nws tsis tuaj yeem hais tias nws muaj kev nyab xeeb kiag li kaw lub qhov muag rau kev tiv thaiv. Yog li ntawd, tsis txhob saib ncaj qha nyob rau hauv lub beam, tsis txhob siv lub Class II laser illumination rau lwm tus neeg lub qhov muag ncaj qha, thiab tsis txhob saib Class II laser nrog deb-pom cov khoom. Cov ntawv thov muaj xws li kev ua qauv qhia hauv chav kawm, laser Pointers, cov cuab yeej pom thiabrangefinders.

Tsuas yog ob hom lasers raug suav rau ntawm no vim Seakeda'sntau sensorcov khoom siv feem ntau siv laser Class I thiab Class II ua cov ntaub ntawv ua haujlwm. Lub laser wavelength yog 620 ~ 690nm thiab lub zog <0.4mW thiab <1mW. Nws muaj kev nyab xeeb siab, ua haujlwm zoo, txuag hluav taws xob ntau dua. Yog li koj tuaj yeem xaiv peb yam xyuam ximlaser range sensor.
