  • High resolution non-contact interior profilometer
    Patent number: 6469794
    Abstract: Apparatus and method for inspecting the interior surfaces of devices such as vessels having a single entry port. Laser energy is introduced into a device under test and to a time delay. Light reflected from the interior surfaces of the device under test is introduced into one end of a dye-cell and the time-delayed light is introduced into the other end. The amount of time delay is adjusted to produce two-photon fluorescence in the dye-cell so that the amount of time delay is representative of the interior surfaces of the device under test.
