  • System and method of detecting the interface between mediums with dissimilar indices of refraction
    Patent number: 6538755
    Abstract: A system and method for determining a location of an interface between media having dissimilar indices of refraction including placing a target having a contrasting pattern on a rear side of a translucent object having boundaries which define the interface between media having dissimilar indices of refraction, observing the substantially translucent object from a front side thereof with an optical observation device, determining an apparent location of the interface based on the observation of the target image through the transparent object, the apparent location differing from an actual location due to refractive displacement of light through the substantially transparent object, and calculating the actual location of the interface based on the determined apparent location.
