Serrodyne Frequency Shift Spectrometer and Serrodyne Frequency Shifting

NIST Inventors

Sean Bresler , John R. Lawall , Benjamin Reschovsky and David Long

Direct multiheterodyne or self-heterodyne frequency comb spectroscopy commonly relies upon the use of an acousto-optic modulator to provide a frequency shift of the resulting radiofrequency interferogram. We have shown that serrodyne modulation can provide this shift, resulting in a significant

Direct Digital Chirp Synthesizer And Generating A Chirped Optical Frequency Comb

NIST Inventors

David Long and Benjamin Reschovsky

Disclosed is a direct digital chirp synthesizer for generating a chirped optical frequency comb that includes: a direct digital synthesizer that receives a repetition frequency signal from a delay generator, receives a clock frequency from a frequency converter, produces a radiofrequency chirp

Optomechanical Ultrasound Detector And Performing Ultrasound Imaging

NIST Inventors

David Long , Thomas W. LeBrun and Jason J. Gorman

An optomechanical ultrasound detector includes: a micromirror substrate; a mechanical resonator that receives ultrasound waves, oscillates at resonator frequency f.sub.r, changes cavity length L.sub.c, and produces intra-cavity light; and an optical microcavity between the micromirror substrate and

Optomechanical Accelerometer And Performing Optomechanical Accelerometry

NIST Inventors

Jason J. Gorman , Thomas W. LeBrun and David Long

An optomechanical accelerometer includes: a fiducial mass for a microscale Fabry-Perot optical cavity; a proof mass for the microscale Fabry-Perot optical cavity, such that the proof mass oscillates in a displacement motion toward and away from the fiducial mass in response to acceleration of the
