YIMA INDAWO
Itafile yodonga, ekwabizwa ngokuba sisiqendu sokugcina, sisixhobo esiguqula ubume bokukhanya kokukhanya ngokuvelisa umahluko wendlela (okanye umahluko wesigaba) phakathi kwamacandelo amabini orthogonal polarization. Xa ukukhanya kwesiganeko kudlula kwiipleyiti zentsimbi ngeendidi ezahlukeneyo zepharamitha, ukukhanya okuphumayo kwahlukile, okunokuba kukukhanya komkara, ukukhanya okuthe tyaba, ukukhanya okuthe tyaba, njlnjl. yeplate yentsimbi.
Iicwecwe zamaza zihlala zenziwe ngezinto ezenziwe nge-birefringent ngobungqingqwa obu ngqo njenge-quartz, calcite okanye mica, ene-axis ethe gungqu yomlomo ifana nomhlaba ofile. Iipleyiti zamaza omgangatho (kubandakanya i-λ / 2 kunye ne-λ / 4 plates) zijolise kulwakhiwo olugqithiselwa ngumoya oluvumela ukusetyenziswa kwawo kwizicelo zamandla aphakamileyo ngomkhamo womonakalo ophakamileyo kune-10 J / cm² nge-20 ns pulses kwi-1064 nm.
Isiqingatha (λ / 2) Iplaza yamaza
Emva kokudlula kwipleyiti ye-λ / 2 ye-wave, ukukhanya okuthe tyaba kumacala asemgceni kusekwe umjikelo ocacileyo, nangona kunjalo, kukho umahluko we-angle (2θ) phakathi kweplanethi yokudibanisa ye-vibration edibeneyo kunye neplanethi yokudlidliza yesiganeko esikhanyayo. Ukuba θ = 45 °, isibane eshukumayo sombane ophumayo siyangqinelana nokuhamba kwendiza yokukhanya kwesiganeko, oko kukuthi, xa θ = 45 °, iplate yentsimbi / i-λ / 2 ingaguqula imeko yepararization nge-90 °.
Ikota (λ / 4) IPlaza yamaza
Xa i-angle phakathi kwesiqhushumbo sokudlwengula kwesibane sokukhanya kwe-polarised kunye ne-optical axis ye-wave plates yi-θ = 45 °, ukukhanya okudlula kwi-λ / 4 yecwecwe leplastiki kuhanjiswa ngaphakathi. Ngaphandle koko, emva kokudlula kumdibaniso wamaza / 4 wokukhanya, ukukhanya okujikelezwe ngumjikelo kuya kubekekilayini. Iapile ye-λ / 4 yeflash inefuthe elilinganayo kunye ne-λ / 2 i-plaza yamaza xa ivumela ukukhanya ukuba kudlule kabini.
