Sign reflectometer

WebThe angle between the illumination axis and the retroreflector axis is known as the entrance angle (β). Simply put, this is the angle at which the light enters the retroreflector, where head-on equals 0°. As such, the entrance angle can only be positive. However, we often use two entrance angle components (β 1 and β 2) which can be positive ...
