A Study on the Photographic Characteristics of Laser Scanner Film

Laser Scanner 필름의 사진특성에 관한 연구

In this study, we made experiments the preparation of silver halide microcrystals, physical ripening, chemical ripening, spectral sensitivity, additives and coating in order to develop medical laser scanner film which has photographic characteristic suitable for exposure to He-Ne and Ar laser. In the practice of sensitometry, the photographic material is exposed to a known quantity and quality of radiant energy, developed under standard conditions, and the densities resulting from the various exposures are then measured. The results are usually expressed in graphic form as curves, and from these curves numerical values are derived which are used to specify the characteristics of the material.
