Measurement of the content of water using light penetration

Abstract

In this paper we use an electronic component to produce light which is applied in testing soft tissue penetration. We used bio tissue, a slice of apple, and non-bio tissue, paper. The voltage could be adjusted to brighten the light to view the penetration of the subject. The thickness of the tissue was constant and the results showed that the current and voltage were significant as the light penetrated the soft tissue.
