회전 편광자 영의 Spectroscople Ellipsometer를 제작하였다. 각 부품의 미소결함에 의한 오차를 추정하고 이들 각 부품의 미소결함이 Ellipsometric 상수들에 미치는 영향을 보정하여 정확도를 향상시키는 관련표현들을 유도하였다. Straight through operation에 대한 성능 평가 결과 파장 대역 400nm-600nm 내에서 tan$\psi$ 와 cos$\Delta$ 의 편차는 0.2% 내외로 만족할 만한 것으로 판단되었다. 광학 박막을 중심으로 Spectroscopic Ellipsomter를 사용한 연구에 대하여 실험예를 중심으로 논의하였다.

We propose a characterization method for the scattering property of microspheres using spectroscopic optical coherence tomography (OCT). To prove the effectiveness of the proposed method, we prepare solutions of different concentrations using microspheres ranging from 28 to 2300 nm in diameter. Time-frequency analysis is performed on the measured interference spectrum of each solution, and the resulting spectroscopic information is converted into histograms for centroid wavelengths. The histograms present a very sensitive response to changes in the concentration and size of microspheres. We classify them into three categories according to their characteristics. When the histogram of each category is replaced with the corresponding calculated value of the scattering coefficient, each category is mapped to a different scattering-coefficient region. It is expected that the proposed method could be used to investigate the optical characteristics of a biological sample from OCT images, which would be helpful for optical diagnostic and therapeutic applications.

The photoluminescence, electroluminescence and surface properties of ZnS:Cu,Cl phosphor coated by sol-gel process were studies. Na-silicate was used as precursor coating material. pH of solution and the concentration of Na-silicate are the important conditions to obtain the uniform coating on the phosphors. Also, the electroluminescent devices were made with Na-silicate coated phosphor. The spectroscopic characterization is performed by photospectrometer.
