YAYE-POLARIZER YESITHILI

Ingcaciso emfutshane:

Iipolarizer zetayile emncinci zenziwe ngezinto eziqulathiweyo ezibandakanya ifilimu eqolayo, ifilimu yokhuseleko yangaphakathi, ungqameko olunamathela ngokudibeneyo, kunye nefilimu yokhuseleko yangaphandle. I-Polarizer isetyenziselwa ukutshintsha ibhulukhwe engacacanga ukuba ibe ngumphambili womgama ocandwe. Xa ukukhanya kudlula kwi-polarizer, enye yeempawu ze-orthogonal polarization ifakwe ngokuqinileyo kwipolarizer kwaye elinye icandelo lifakwe buthathaka, ke ukukhanya kwendalo kuguqulwa kube ngumgaqo ocacileyo wecolar.

Iimpawu zeemveliso

Iipolarizer zetayile emncinci zenziwe ngezinto eziqulathiweyo ezibandakanya ifilimu eqolayo, ifilimu yokhuseleko yangaphakathi, ungqameko olunamathela ngokudibeneyo, kunye nefilimu yokhuseleko yangaphandle. I-Polarizer isetyenziselwa ukutshintsha ibhulukhwe engacacanga ukuba ibe ngumphambili womgama ocandwe. Xa ukukhanya kudlula kwi-polarizer, enye yeempawu ze-orthogonal polarization ifakwe ngokuqinileyo kwipolarizer kwaye elinye icandelo lifakwe buthathaka, ke ukukhanya kwendalo kuguqulwa kube ngumgaqo ocacileyo wecolar.

I-Optical ye-polarization ibalulekile ekusebenziseni i-intra kunye nokusetyenziswa okuthe kratya. Ngokwenza umahluko omkhulu kwiipolarists zefilimu ezityhidiweyo kuyilo lwazo, iinjineli ze-laser zinokusindisa ubunzima kunye nevolumu ngaphakathi kwezixhobo zazo ngaphandle kokuchaphazela ukuphuma kwazo. Xa kuthelekiswa ne-polarizing prism, ipolarizer ine-angle yeziganeko ezinkulu kwaye inokwenziwa nge-apertures ezinkulu. Xa kuthelekiswa neepolarizer ezenziwe kwiikristale ze-birefringent, inzuzo yeefolda ezincinci zefilimu kukuba zingenziwa ngobukhulu obukhulu, ke ngoko zinokusebenza kwisixhobo se-laser ngamandla amakhulu okanye amandla.
