Daim ntawv thov ntawm microchip lasers hauv lub zos

Microchip Lasers, tus cwj pwm los ntawm lawv cov duab teeb monolithic, cov nqaj loj zoo, thiab tshwj xeeb yog los ntawm kev siv tshuab lub teeb kom pom kev zoo thiab txij li lub tsev). Raws li Lidar Systems ua cov thuam tseem ceeb rau kev siv liconomous tsav tsheb uas ib txwm siab {{{{2} - siv tau zoo.

1. Pib

1.1 Tus txheej txheem cej luam ntawm Lidar Technology
Kev kuaj lub teeb pom kev zoo (Lidar) yog qhov kev hnov ​​ntawm cov chaw taws teeb uas ntsuas qhov teeb meem nrog laser teeb thiab kev tshuaj ntsuam cov teeb liab. Ib txwm Lidar system muaj peb qhov kev sib xyaw ua ke: ib lub tswv yim laser, thiab lub tshuab nqus tsev (tshuab, lossis cov khoom siv- lub xeev). Los ntawm xam lub sij hawm - ntawm {4} {} Lub davhlau (TOF) ntawm cov mem tes Laser) Nws cov ntawv thov ncua tsheb kawm ntawv qib siab, Robotorics cov chaw ua si, thiab cov khoom lag luam tsis muaj zog ntxiv, ntev dua, me dua daim ntawv, thiab tus nqi qis dua.

1.2 Qhov kev thov rau cov khoom lag luam zoo tshaj plaws
Cov kev ua tau zoo ntawm lub haurar system yog cov qauv siv los ntawm cov yam ntxwv ntawm nws txoj haujlwm laser. Lub hauv paus siab zoo tshaj plaws yuav tsum txaus siab qhov kev xav tau ntawm qhov yuav tsum tau ua:

High Peak Lub Zog:Qhov tseem ceeb rau kev tshawb fawb ntev - muaj ntau, kev kov yeej cov atmospheric attenuation.

Nqaim mem tes dav:Tseem ceeb rau kev ua siab loj thiab daws teeb meem (sub - cm lub peev xwm).

Beam zoo heev (ze - diffraction - TSUA):Xyuas kom muaj qhov chaw me me, tsom mus rau cov kev ncua deb, uas ncaj qha txhais kom muaj kev sib cais thiab cov kev ntxub ntxaug.
