Abstract
: In order to realize the on-line accurate measurement of turbidity of traditional Chinese medicine ( TCM), the
spectrum characteristics analysis method was used to establish the relationship between the spectrum characteristics and turbidity
of the transmitted and scattered light signals. A near-infrared LED was employed as the light source of the sensor. The
transmitted light and scattered light signals were converted into weak current sign
