본 연구에서 우리는 다양한 종류의 패각을 사용하여 진주패각에서 나타나는 컬러 및 광학적 현상에 대해 비교 분석하였다. 다양한 종류의 패각의 진주층 단면 및 표면 SEM 이미지와 FFT 시뮬레이션을 수행했다. 그리고 반사율 측정을 통하여 패각에서 나타나는 광학적 현상에 대해 규명하고 패각의 광학적 현상에 의해 모패를 감별하기 위한 데이터를 구축하였다. 또한 패각의 진주층 구조에 기인한 회철현상을 바탕으로 하여 여러 각도의 분광반사율을 측정해서 보는 각도에 따라 패각의 색이 달라지는 현상에 대해 분석하였다.
Optical properties and color analysis of nacreous layers were performed using various pearl shells. The cross section and microstructure of the surface in each nacreous layers were observed through a SEM (Scanning Electron Microscope), and the diffraction pattern on SEM images was analyzed using FFT (Fast Fourier Transform). Through these analysises, it was verified that the color and optical characteristics are closely related to the structure of nacreous layers. Incident angle-dependent reflection spectrum was used to examine the phenomena of color differenceas the direction of observation. Quantified values on the color change were obtained by CIE L*a*b* color scale. Using this research, database for the characteristics of natural pearl shells can be established, and the precise analytic method for observation of pearl shells was suggested.
