在医学上激光的应用越来越多。某些应用已包括了测定视网膜和皮肤血管的血流量、心脏检查、内窥镜检查、外科学以及皮肤病学等。在这些应用中需要了介这些器官的反射特性,以便介决分析各个参量时的暴光程度。例如心脏检查,根据胸壁的反射特性,以便全息照相底片所要求的暴光量能够调到安全的暴光限度是重要的。现仅对确定身体各部位反射率特性的测定技术,以及有关问题作如下简要的介绍。组织的总反射率是由表面和该表面下各层的反射作用所造成的。由于组织的这些反射作用如同GOLDMAN和ROCKMWELL(1671)曾观察到的那样是遵守朗伯定律的,
In medicine, the application of laser is more and more. Some applications include measuring blood flow to the retina and cutaneous blood vessels, cardiac exams, endoscopy, surgery and dermatology. The reflection properties of these organs are required in these applications in order to determine the degree of exposure when each parameter is analyzed. For example, cardiac examination, based on the reflective properties of the chest wall, so that the amount of exposure required for holographic negatives can be adjusted to a safe exposure limit is important. Now only to determine the various parts of the body reflectance characteristics of the determination of technology, and related issues are briefly described below. The total reflectance of the tissue is caused by the reflection of the surface and the layers beneath it. Since these tissue reflexes follow Lambert’s law as observed by GOLDMAN and ROCKMWELL (1671)
