The optical characterization methods were used in the study of the defects of transparent crystal in visible light and the near UV absorption topography method is used in the study of the defects and relationship between defect and growth facets because scintillant BGO crystals, when suffered radiation damage,have a high absorption coefficient for light of short wavelength.

除使用通常研究透明晶体的光学方法外，由于BGO晶体在受到光辐照损伤时时短波长光具有高的吸收系数，因此还采用近紫外光吸收形貌法研究晶体缺陷，以及缺陷与晶体小面之间的关系，并根据BGO晶体的结晶习性和小面形成机理提出了减少和消除晶体小面生长及缺陷的方法。

The optical dot gain results from basically the light scattering in substrates. In ink-jet printing the ink penetration changes the optics of the coating of the substrates including the light scattering coefficient and absorption coefficient. So it affects the optical dot gain greatly. The application of Kubelka-Munk Theory in halftones is also studied, and so an ink penetration model is established using K-M theory. The penetration depth and the scattering and absorption coefficients are decided.
