Claim Text:
1. A profilometry system, comprising: a radiation source for delivering a structured radiation pattern to an object, wherein the structured radiation pattern has a first frequency content; and a detector operable for detecting a resulting deformed radiation pattern reflected or emitted from the object, wherein the resulting deformed radiation pattern has a second different frequency content and a different spatial configuration; wherein a conversion from the structured radiation pattern to the resulting deformed radiation pattern and a corresponding conversion from the first frequency content to the second different frequency content are due to the absorption and emission of radiation by the object; wherein the first frequency content comprises one of an ultraviolet wavelength, a visible wavelength, a near-infrared wavelength, and an infrared wavelength; and wherein the second different frequency content comprises one of a different ultraviolet wavelength, a different visible wavelength, a different near-infrared wavelength, and a different infrared wavelength.
