Experience:
Medical:
Electro-Optical
Sciences, Inc. Performed the
system analysis and analyzed the pre-production procedures of a hyperspectral
medical imager designed to identify melanomas.
OcuSciences.
Inc. Designed the
diffraction-limited optics and dual illumination system (white light &
fluorescence) for a medical retinal imager to detect the early onset of
diabetes.
Inner Vision
Imaging, Inc. Responsible for
the development and production of the visible-optics section of a medical
laparoscope to detect cancer cells in living human tissue. Designed the optical zoom system and the
electro-mechanical servo system to drive it.
Performed a tolerance analysis of all the optics to ensure the device
could be built in production quantities.
Designed the lens cells and the lens measuring equipment which enabled
the complex relay system to be built to diffraction-limited performance
levels. Designed the white light
illumination system.
University of
Michigan Designed and built a
16 channel interface device to carry the electrical signals from an active
rodent’s brain to a computer.
Space and Military:
Oasis Advanced
Engineering Inc. Designed a Switchable Vision Block for armored
vehicles, which allows real or virtual graphics to be overlaid on the tank
commander’s outside view. This is
similar to the heads-up displays in F-16 aircraft. Performed all of the optical and mechanical
design work and provided the customer with complete documentation and test
procedures for building the device.
General
Dynamics – Advanced Information Systems Designed the optical system for an orbiting,
three wavelength band, scanning optical system to track and identify other
satellites. Bands were VNIR, LWIR, and
microwave.
Google Earth Designed
the optics for a 0.6 meter orbiting pushbroom satellite to map the entire Earth
to a resolution of 1.2 meters. The optics
are diffraction-limited across a 2.3 degree flat field of view. Performed the thermal analysis of the optical
and mechanical systems to ensure that they meet the resolution requirements
throughout the earth-orbit thermal cycling.
Michigan
Aerospace Corporation Designed
an airborne imaging spectrograph which utilized three progressive sets of Fabry-Perot
interferometric etalons to achieve high resolution of air velocities. Special attention was given to reducing stray
light to extremely low levels.
Microcosm, Inc.
Designed an extremely small 3FOV
Star-Tracker using invar housings and Zerodur optics. Device was designed for use in portable
backup systems if the GPS fails.
Michigan
Aerospace Corporation Designed
parts of the mechanical package for a very high resolution laser Doppler
ranging system for a weather satellite and for an airborne LIDAR system. The work included lens, flexure, and etalon
plate mounts, vacuum and cooling systems, and fiber optic and CCD detector mounts.
ERIM Designed the motion stage of a vision system
to track the growth of human tissue in a locker-based experiment on the Space
Shuttle.
Boston
University Designed and built
the Zerodur optics, Invar mounts and the support structure for a 14” F/21.4
extreme ultraviolet telescope. The
design maintained its optical alignment through the thermal cycling and 20
gravity bump and spin up of the launch rocket during the course of its flight
from the desert, to above the atmosphere, to its return to Earth.
Commercial Products
Kaiser Optical
Systems, Inc. Invented,
developed, and saw into production a patented FC optical fiber connector, which
locates single-mode fibers to sub-micron accuracy while accommodating oversize
ferrules, for a commercial Raman holographic spectrograph manufacturer. Designed and built the production fixtures
which were necessary to produce the connectors in quantity. Performed the opto-mechanical design and
stress analysis to ensure that they could be built on a production basis and
would survive in the field.
Kaiser Optical
Systems, Inc. Designed a
thermally compensated spectrograph which incorporated a volume-phase
holographic grating, using the thermal compensation features of Zemax. Designed and built a production device to
improve the optical alignment and resolution of the spectrograph lenses. Designed lens housings which would not
distort the lens elements upon thermal cycling.
IMRA America Designed the
mechanical package for the commercial production of a fiber-optic femtosecond
laser.
ArgonST
Analyzed the effects of changing the detector type and cold shield position of
a three-field-of-view MWIR telescope.
