Ua Haujlwm Me Me

1) magnetoelectric nyhuv

Raws li cov kev cai Faraday txoj cai ntawm hluav taws xob induction, qhov kev sib nqus ntawm cov sib nqus ntawm cov sib nqus thiab cov sib nqus

Linear txav Magnetoelectric sensor

Cov kab txav txav mus los ntawm Magnetoelectric sensor muaj cov hlau nplaum tas mus li, ib coil thiab lub tsev nyob.

Thaum lub plhaub vibrates nrog lub cev vibrating kom raug ntsuas thiab ntau zaus yog qhov loj dua, nws yog lig dhau lawm, nws yog lig rau kev txav mus rau qhov chaw txav mus rau qhov kev txav mus rau lub cev. Nyob rau lub sijhawm no, qhov txheeb ze suab nrawm ntawm cov hlau nplaum thiab cov kauj yog ze rau qhov kev co ntawm lub vibrator.

Hom teb

Cov hlau mos, chev thiab cov hlau nplaum tas mus li yog tsau. Qhov ntsuas iav ua los ntawm cov khoom siv sib nqus tau raug teeb tsa ntawm lub cev ntsuas tig. Txhua txhua lub sij hawm ib tus hniav tau tig, lub sib nqus tiv thaiv ntawm cov hlau nplaum tsim ntawm cov ntsuas sib nqus ib zaug, thiab sib nqus flux kuj hloov ib zaug. Qhov ntau zaus (naj npawb ntawm cov pulses) ntawm cov inducteromotive quab yuam hauv kauj yog sib npaug rau cov hniav ntawm cov ntsuas ntsuas thiab ntsuas nrawm.

Lys effect

Thaum lub semiconductor lossis hlau ntawv yog muab tso rau hauv cov ntawv sib nqus ntawm cov ntawv sib nqus yog tsim tawm hauv cov kev sib nqus mus rau qhov sib nqus thiab cov khoom sib nqus thiab tam sim no. Qhov tshwm sim no yog hu ua Lall nyhuv.

Phab tsev

Cov ntaub ntawv siv feem ntau yog German (ge), si), indium antimonide (insb), Infium arsenide (inas) thiab lwm yam) thiab lwm yam) N-hom germanium yog ib qho yooj yim rau kev tsim khoom thiab muaj cov thawj coj zoo me me, qhov kub thiab linearity. P-hom Silicon muaj qhov zoo tshaj plaws linarity, thiab nws cov cuab yeej coefficient thiab nws lub peev xwm hluav taws xob yog qhov tsis zoo, yog li nws feem ntau tsis yog siv los ua ib txoj kev sib tw.
