Patent number: 11460607Abstract: An apparatus includes a substrate, a first patterned layer, and a second patterned layer. The first patterned layer may be coupled to the substrate and may have a first metasurface pattern. The second patterned layer disposed separately from the substrate and the first patterned layer, and may have a second metasurface pattern. Movement of the first patterned layer relative to the second patterned layer may be controllable via control circuitry such that a gap distance of a gap between the first patterned layer and the second patterned layer is changed to cause a transmittance for radiant energy of a selected wavelength passing through the apparatus to change from a first transmittance value to a second transmittance value.Type: GrantFiled: July 4, 2019Date of Patent: October 4, 2022Assignee: The Johns Hopkins UniversityInventors: David B. Shrekenhamer, Luke J. Currano, Konstantinos Gerasopoulos, Joseph A. Miragliotta, Joshua B. Broadwater, Garret T. Bonnema

Patent number: 8928888Abstract: A method and apparatus are provided for a swept source optical coherence tomography (OCT) system utilizing a fast scanning mechanism in the sample arm and a slowly swept light source. The position data is collected rapidly while the wavelength of the source is swept slowly. The system reduces the sweep speed requirements of the light source enabling higher power, greater imaging range, and linear sweeps of the source frequency. The OCT components (or most of them) may be implemented within a hand held imaging probe. In operation, a triangulation scan may be used to orient the imaging probe with respect to a fixed coordinate system; preferably, OCT data captured by the device is then transformed to that same orientation with respect to the fixed coordinate system to improve the scanning results.Type: GrantFiled: December 28, 2012Date of Patent: January 6, 2015Assignee: D4D Technologies, LLCInventors: Garret T. Bonnema, Henley S. Quadling, Mark S. Quadling

Publication number: 20140303474Abstract: An aid to diagnosing at least one of infiltration and extravasation in Animalia tissue includes an optics bench and a controller. The optics bench includes a light emitting diode and a photodiode. The light emitting diode is configured to emit a first light signal, and the photodiode is configured to detect a second light signal. The second light signal includes a portion of the first light signal that is at least one of reflected, scattered and redirected from the Animalia tissue. The controller includes a processor, volatile memory and non-volatile memory. The non-volatile memory stores a sequence of values that correspond to the second light signal detected by the photodiode. The processor and volatile memory analyze the sequence of values according to an algorithm.Type: ApplicationFiled: April 4, 2014Publication date: October 9, 2014Applicant: ivWatch, LLCInventors: Gary P. Warren, Matthew S. Alley, Javier A. Garriz, William J. Naramore, Garret T. Bonnema
