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.

13.5 nm EUV Lithography: Tin Droplet Detection System

When you're hitting a droplet with enough pulsed CO2 light to generate X-rays efficiently, you have to know exactly when it's going to cross the focus.
