Pete’s project list
Here’s a link to a pdf copy of Pete’s resume, or you can a list of his projects on line below.
“Pete is primarily the optics and mechanical engineering part of the team,
but our skills overlap – he’s familiar with electronics, and he keeps me out of trouble”,
I apply engineering and physics knowledge to technical product design and industrial problems
This instrument produced full sized holograms of 3D medical scans. Its foot print was 2.5 ft by 9 ft. I designed the optics path, and was responsible for the engineering of the first prototype.
This device is the size of a white-board marker. It reads 2D bar codes that direct a browser to a specific web site. I designed and built a prototype lens and LED illumination system.
DNA ARRAY READER
This product is a scanning confocal microscope, with laser excitation and fluorescence detection. I devised the scanning method, and worked with the team that put it into production. I have extensive experience with narrow band filters, commercial lasers, photo-multiplier tubes, and opto-mechanical debugging.
For this product I invented a novel pin and ring method for obtaining DNA samples from 96 well plates and depositing spots of DNA onto a microscope slide. I also was the project manager during the company start up phase.
I use Zemax for imaging lens design, laser beam telescope design, scanner mirror design, and analysis of existing systems.
This black box produces 4k X 5k images on 14 X 17 inch dry silver film. The light source is a near IR diode laser, the image was scanned mechanically with a resonant scanner and a precision galvanometer. I designed the optical path, and 2 generations of the resonant scanner. I supervised the effort of an outside lens designer.

MICRO IR SPECTROMETER
The dispersive element of this device is a 1 mm thick silicon waveguide fabricated with a combination of classical optic shop practice and modern vacuum processing techniques such as electron beam lithography. The completed device will fit inside the 1 inch bore of a drill used for Mars geology surveys.
I started working on the project to assist the PI in through ray trace studies using the non-sequential capabilities of Zemax. During this phase I brought the Zemax macro capability in house to partially automate the analysis and reporting process. I designed the illumination system, and bench tested it, verifying the predictions of the modeling phase. Presently, while working under the direction of the company’s CTO, I am working with the outside people involved in fabrication, breadboard testing elements of the waveguide, and designing the tooling for the assembly of terrestrial test devices.
This clever device is based upon the animal studies of 2 Tufts professors. Fitler testing, air flow measurement,
