Dr.
Donald Barnhart
Donald Barnhart has been developing optical design and analysis software in Mathematica since
1991. His Optica software package, introduced in 1994, is used by thousands
of scientists across the world. Donald developed the world's first successful high-resolution holographic
instrument to measure three-dimensional velocity fields in fluids, the results
of which appeared on the front cover of Applied Optics in 1994 and are cited
in over 200 publications. Donald received the Rank Prize in 2001 for the best
electro-optics Ph.D. dissertation in the United Kingdom. The optics group to
which he belonged at Loughborough University received the Queen's
Anniversary Prize, awarded personally by the Queen at Buckingham Palace.
Since 2004 Donald has been the chief optical scientist for iCyt Mission Technology,
a Sony USA subsidiary that produces flow cytometers for stem cell and cancer
research, in addition to his ongoing Optica business.

with were submitted as part of the groups portfolio for this award. This is a
prestigious prize in the United Kingdom. (I traveled to Buckingham Palace and
met with the Queen of England for this award.) |

Professional Interests
|
-
As the lead developer of Optica Software, I am continually developing
this software as a consultant for new business applications in a wide range of
professional settings involving optical systems design and modeling.
-
A second professional interest involves the development of a fully digital
holographic camera with numeric reconstruction of the digitized holographic information.
In particular, I am using a photochromic material, known as bacteriorhodopsin
(BR), as a temporary optical storage buffer to allow the holographic information
to be digitally scanned1. This use of BR for digital holography is a completely
new concept that I have personally originated. In contrast to a CCD camera sensor,
which can only record millions of pixels, a digital holographic camera based
on BR can record 10-100 billion pixels of information. This corresponds to a
holographic object space that occupies 1-10 cubic centimeters volume with sub-micron
spatial resolution. The two principal applications of this instrument are in
the areas of biomedicine and nanotechnology research:
-
three-dimensional, velocity-field mapping of fluids, surfaces, and surface-flow
interaction,
-
digital holographic microscope for high-resolution, volumetric imaging.
-
A third interest is the development of new optical instrumentation for remote
sensing. This interest is connected with a personal endeavor to restore more
than 100 acres of farmland into native tall grass prairie (see below). Although
my experience in this research area is still limited, I wish to develop new instrumentation
for mapping out species distributions in high-diversity, natural plant communities,
such as the tall grass prairie, on a spatial scale that enables the individual
plants to be accurately located, identified, and cataloged. In addition, the
same instrumentation can have applications in commercial agriculture, for which
research/business funding is more abundantly available.
