Nyob rau hauv kev siv xws li holography, biomedical imaging, aberration correction, laser processing, thiab dawb-qhov chaw optical kev sib txuas lus, electronically tshuaj kho qhov muag theem pib ua nrov nrov. Tam sim no, muaj ntau lub tshuab yees uas yuav siv los hloov cov theem ua ntej, nrog rau MEMS (Micro-Electro-Mechanical System) thiab Lub Caj Moos Siv Liquid Crystal (LC) -Txoj Kev Ntsuas Hluav Taws Xob Nruab Nrab (SLM). Optical MEMS theem modulators nrog tsav tsheb thiab micromirrors tau tsim los ua me me hauv kev siv zog thiab me me loj. Cov kev zoo no nws cia nws tsa ntau tus kab teeb meem ib txhij. Txawm li cas los, kho qhov muag MEMS raws theem theem modulators feem ntau muaj pixel densities ntau dua li lwm hom modulators thiab feem ntau muaj kev tswj kom muaj zog ntawm kev sib tw ntawm kev sib tw.
Nyob rau hauv qhov zoo tshaj plaws qhov teeb meem, SLM muaj ob theem siab (analog) theem tes taws los piav thiab tus nqi siab. Rau qhov kawg no, Stockley li al. npaj ib qho kev kho qhov muag analog theem zauv raws li kev sib txuas ntawm cov dej ua kua siv ferroelectric thiab ib lub cev ua kua polymer cholesteric kua hauv 1995. Ntawm qhov kev kho, qhov sib txawv theem pib yog 1.95π. Tab sis cov ntaub ntawv thov voltage yog non-linear heev.
Cov kws tshawb fawb British tau nrhiav pom qhov nruab theem ntawm cov qauv kho qhov muag raws li cov qauv electronically kho qhov cwj pwm ntawm collimated chiral nematic kua muaju raws li uniformly arranged helix (ULH, Uniform Lying Helix). Ua ntawv thov ib qho hluav taws xob ntawm 4 V / μm ntawm qhov kub ntawm 106 ° C, cov qauv no muaj peev xwm muaj kev hloov pauv hloov 2π thiab tiav qhov kev hloov ntawm qhov sib txawv. Cov qauv no tau tsim rau hauv ib qho khoom siv ntim rau ib lub teeb nrig silicate spatial. Kev loj hlob muaj peev xwm zoo. Daim ntawv tshawb fawb no tau luam tawm nyob rau hauv txoj kev kawm ntawv "NPG Asia Cov Ntaub Ntawv" ntawm Pawg Neeg Tshawb Fawb.
