摘要：

Biodegradable polymers exhibit major surface changes that cannot be measured by gravimetric methods. This paper describes a simple, inexpensive system that can accurately record these surface changes. It is based on a laser light source and a scanning photodiode controlled by microcomputer. © 1990.
