Sisitimu Yekuyedza yeLPT-4 yeLC Electro-Optic Effect

Tsananguro pfupi:

Zvakanakira
1. Chishandiso chekutungamira simbi, chinotsvedza, chinotenderera, nezvimwewo zvakagadzirwa nearuminiyamu yakasimba, uye chinhu chakamira chakagadzirwa nesimbi isingatsvedzi. Chine zvakanakira zvehukuru hudiki, huremu hushoma, uye hachina ngura. Chishandiso chekutungamira chakagadzirwa zvakanaka uye chinogona kugadziriswa zvakanaka. Chishandiso chekutungamira chinoshandisa chimiro chemuswe wedovetail, icho chakaiswa zvakanaka mumutsara wakatwasuka panguva yekufamba uye chakasimbiswa zvakasimba uye zvakavimbika.
2. Gadzirisa LCD sample nechimiro chefuremu, chakasimba uye chinoyevedza; Kushandisa terminal posts kuti uise simba pasample kuri nyore uye kwakachengeteka.
3. Zvese zvinoshandiswa mumidziyo zvinoshandiswa zvinoshandiswa ne optical universal accessories (kusanganisira optical power meters). Pamusoro pekushandiswa pakuedza kwe liquid crystal electro-optic effect, zvinogonawo kushandiswa pakuedza kwe optical senge polarization kana kuyera hukama huripo pakati pe operating current uye output light intensity ye semiconductor lasers.

Matagi eChigadzirwa

Kuedza

1. Yera electro-optic curve yemuenzaniso we crystal yemvura wobva wawana ma electro-optic parameters akadai se threshold voltage, saturation voltage, contrast, uye steepness yemuenzaniso.
2. Oscilloscope yekuchengetera data yedhijitari inogona kuyera curve yemhinduro ye electro-optical yemuenzaniso we crystal yemvura uye kuwana nguva yekupindura yemuenzaniso we crystal yemvura.
3. Inoshandiswa kuratidza musimboti wekuratidza wechinhu chiri nyore kwazvo che liquid crystal display device (TN-LCD).
4. Zvikamu zvechikamu zvinogona kushandiswa pakuedza chiedza chakapatsanurwa kuti zvisimbise kuedza kwemaziso kwakadai semutemo waMarius.

Magadzirirwo

Laser ye semiconductor	Voltage yekushanda 3V, inoburitsa 650nm mwenje mutsvuku
LCD sikweya mafungu emagetsi	0-10V (kukosha kunoshanda) inogadziriswa nguva dzose, frequency 500Hz
Mita yemagetsi yeOptical	Range yacho yakakamurwa kuita mazinga maviri: 0-200wW uye 0-2mW, ine LCD display ine manhamba matatu nehafu.
