Transdermal glucose detectors based on optical coherence tomography

This was a photon budget for an OCT system—interesting primarily for the effect of path delay in turning FM noise in the superluminescent diode (SLD) into AM noise in the measurement.

High resolution touchscreens

This was for a midsize start-up making very large, high resolution touchscreen displays—they needed an outside pair of eyes to do some sanity checking of a couple of their proposed designs.

Mixed-reality head-mounted projection displays

I chaired a series of formal design reviews for a start-up company making immersive displays with resolution better than the human eye.

All-Optical Downlink for Antisubmarine Warfare (ASW) sonobuoys

Another Della project for the Navy: I did a photon budget that showed that this could be done optically within the power and weight constraints, and would work in bright sun as well as at night. (Optical communications are much harder to intercept or to jam than radio.)

Integrating vs. TIA front ends for compressive-scan cameras

A shootout between the two major classes of transimpedance amplifier (TIA) designs for one difficult corner of the design space.
