Saamaynta Piezoelectric

Marka qaar ka mid ah dielectrics ay qallafsan yihiin iyaga oo isticmaalaya xoog jiho gaar ah, kharashyada ayaa laga soo saaraa meel gaar ah, marka xoogga dibadda laga saaro, waxay ku noqdaan xaalad aan la dallacin. Dhacdadan waxa lagu magacaabaa saamaynta piezoelectric togan. Marka beer koronto lagu dabaqo jihada polarization ee dielectric, dielectric waxay soo saari doontaa cillad farsamo ama cadaadis farsamo oo jihada gaar ah. Marka goobta korontada ee dibadda laga saaro, qallafsanaanta ama walbahaarka ayaa meesha ka baxaya, taas oo loo yaqaan saameynta piezoelectric.

Curiyaha korontada

Dareemka Piezoelectric waa dareeme jireed iyo dareeme koronto. Qalabka piezoelectric ee sida caadiga ah loo isticmaalo waa Shi Ying crystal (SiO2_2) iyo ceramics piezoelectric synthetic.

Joogtada piezoelectric ee ceramics piezoelectric waa dhowr jeer ka Shi Ying crystal, iyo dareenkiisu waa sare.

4) Transducer sawir qaade

1. saamaynta korantada

Marka iftiinku iftiimiyo shay, waxa loo qaadan karaa xadhig photon ah oo tamar leh e duqaynaya shayga. Haddii tamarta photons ay ku filan tahay, elektaroonnada gudaha walaxda ayaa ka takhalusi doona caqabadaha xoogga gudaha waxayna yeelan doonaan saameyn koronto oo u dhigma, taas oo loo yaqaan saamaynta sawir-qaadista.

1) Marka la eego ficilka iftiinka, ifafaalaha ay elektaroonadu ka baxsadaan dusha shay waxaa loo yaqaannaa saamaynta sawir-qaadista dibadda, sida tuubbada sawir-qaadista iyo tuubada sawir-qaadista.

2) Marka la eego ficilka iftiinka, ifafaale in iska caabin shay uu isbeddelo waxaa loo yaqaan 'internal photoelectric effect', sida photoresistor, photodiode, phototransistor iyo phototransistor.

3) Marka la eego ficilka iftiinka, shaygu wuxuu soo saaraa awood elektromotive ah jiho gaar ah, taas oo loo yaqaan 'photovoltaic phenomenon', sida unugga sawir-qaadista (qalab xasaasi u ah booska iftiinka dhacdada ee dusha sare ee sawir-qaadista).

2 iska caabin sawir leh

Marka sawir-qaadaha uu iftiimiyo iftiinka, elektaroonnada ayaa u guura si ay u soo saaraan lammaane-dalool elektaroonig ah, taas oo ka dhigaysa iska caabbinta yar. Iftiinku wuu sii xoogaystaa, waa uu hooseeyaa caabbinta. Iftiinka dhacdada wuu baaba'aa, lamaanaha godka elektarooniga ah ayaa soo kabanaya, qiimihii iska caabintuna si tartiib tartiib ah ayuu ugu soo noqonayaa qiimihiisii ​​asalka ahaa.

3. Tuubbada dareenka leh

Tuubooyinka xasaasiga ah (photodiode, phototransistor, phototransistor, iwm.) waxay ka tirsan yihiin aaladaha semiconductor.

4. Electroluminescence

Ififaalaha luminescence-ka ee ay soo saaraan walxaha luminescent-ka adag ee ka hooseeya kicinta beerta korantada waxaa loo yaqaan 'electroluminescence'. Electroluminescence waa hab si toos ah tamarta korontada loogu beddelo tamarta iftiinka. Diode iftiimiya (LED) waa qalab koronto-dhaliye ah oo lagu dhejiyay walxo gaar ah. Marka isku xirka PN hore loo eego, tamar xad dhaaf ah ayaa soo baxda sababtoo ah dib-u-habaynta daloolka elektarooniga ah, kaas oo lagu sii daayo qaab sawir-qaade ah oo iftiimiya iftiin.
