Abstract

Optical sensing system for detecting an electric field and decomposed gas is proposed by using a sensor head which consists of a comer cube prism, nematic and choresteric liquid crystal (LC) cells. The electric field can be detected at the wavelength of the selective reflection band of choresteric LC and electrically induced birefringence in the nematic LC cell. The decomposed gas can also be detected as spectra changes of methyl orange film deposited on the comer cube prism.
