It can be seen that the technique of using properly selected filters to provide rigidly defined monochromatic bands with which to observe the fundus presents interesting and challenging information that is as yet mainly untapped. The applications quoted present only a small part of the areas that can be investigated. The technique is basically standard, but advances can still be made in optimizing filters. The question of what band width to use for a given application is by no means solved and presents a challenging avenue of inquiry. It should be pointed out that the use of color film with interference filters offers no advantage. The only dimension being recorded at each point in the film is reflectivity of the structure at the wavelength of the filter being used. Documenting the color of this wavelength by the use of color film is a fruitless exercise.
可以看出,使用经过适当选择的滤光片来提供严格定义的单色带以观察眼底的技术,呈现出有趣且具有挑战性的信息,而这些信息目前主要尚未得到充分利用。所引用的应用仅代表了可研究领域的一小部分。该技术基本是标准的,但在优化滤光片方面仍可取得进展。对于给定应用应使用何种带宽的问题远未得到解决,并且是一个具有挑战性的研究途径。应该指出的是,使用带有干涉滤光片的彩色胶片并无优势。胶片上每个点所记录的唯一维度是在所用滤光片波长下结构的反射率。通过使用彩色胶片记录该波长的颜色是徒劳的。
