Abstract
A method for determining a transmittance of light on oral tissue is provided, comprising: providing an LED; directing light from the LED onto a sample of oral tissue; measuring a first power of the light at a first surface of the sample; measuring a second power of the light at a second surface of the sample; computing surface loss of the light; and determining the transmittance of the light using the first power, the second power, and the surface loss.
