Latest Patents

Chan's latest patents include a broadband profiler system and a method for constructing a three-dimensional profile of a target. This three-dimensional profiler utilizes a broadband radiation source and an interferometric system that comprises first and second beam splitters, a moving time delay-inducing reflector, and a stationary reflector. The system is designed to create a time-delayed optical sample radiation source and an optical reference incident radiation source. A stationary sample holder receives the optical sample incident radiation, while a reference plane receives the optical reference incident radiation. A detector captures an interference signal from reflected or scattered optical sample radiation and reflected or scattered optical reference radiation. The processor then extracts an optical path difference between the reference plane and the sample, reconstructing a three-dimensional morphology of the sample.

Another significant patent is the time-temperature indicator (TTI) that employs polymer hardening properties to retain indications of temperature history. This TTI consists of a mesh layer affixed to a thermo-conductive adhesive layer and a photonic crystal patterned film. The photonic crystal exhibits a property of bandgap shift versus temperature, responding to a predetermined range of temperatures to provide a visible indication. A hardener pouch is attached to one end of the mesh layer, releasing hardener in response to an initiating event, allowing the photonic crystal material to present a fixed state.
