College of Optical Sciences News for March 22, 2007

 

Today:  Colloquium -- March 22, 2007 -- 3:30 p.m. -- Meinel 408

 

J. Scott Tyo, University of Arizona College of Optical Sciences, will present Sensing Higher Order Image Information at the Focal Plane Array.  Stanley Pau is the host.  Abstract:  Spectral and polarimetric imagery have emerged as tools that can assist in a range of sensing applications.  In many cases, it is desired to create a spatial image where either the spectrum or polarization (or both!) are measured at every pixel across a scene.  Numerous strategies have been suggested that enable such data to be measured, and each strategy has its own drawbacks.  One class of sensing strategy that has applicability in certain scenarios could be termed integrative sensing.  In these methods, the focal plane array itself is specially designed to inherently sense the information that is sought after.  This talk will discuss two efforts to accomplish this, one for polarimetry and one for spectral imagery.  For the past several years, we have been working with the Air Force Research Lab to operate a LWIR, division of focal plane, imaging polarimeter.  This device integrates an array of micropolarizers with a HgCdTe detector to create an inherently polarization sensitive device.  The advantages of the system is that the data is inherently aligned, both mechanically and temporally.  The disadvantage is that neighboring pixels - each viewing a different polarization state - have different instantaneous fields of view.  This IFOV error leads to false polarization signatures, especially near edges within the image.  I will discuss our efforts towards calibration of this system and compensation for the errors, and will present a range of imagery data indicating the utility of the system.  In our second effort, we are developing electronically-tunable IR FPAs for spectral sensing.  We have developed IR photodetectors based on nanoscale, self-assembled quantum dots.  These dots are grown in a quantum well, providing a number of parameters that can be used to tailor the potential contour.  Through the use of asymmetry, these devices can be made to have a spectral responsivity that changes as a function of the bias voltage applied across the detector.  We have developed noise-tolerant postprocessing strategies that allow us to infer spectral information by taking multiple measurements of a scene at different biases.  The advantage of such a system over conventional spectral sensors include: 1) the biases can be chosen at the time of collection, making the system adaptive; 2) the biases should be switchable at video frame rate; 3) the system can operate as a broadband thermal imager, a two-color camera, or in a multispectral mode without changing any hardware on the system.

 

Pouria Valley
Receives OSC's First
Outstanding Graduate Student Award

 

Nominated by his advisor, Nasser Peyghambarian, Pouria was selected to receive the award on the strength of his willingness to seek new challenges and opportunities and to accept responsibility over and above his academic, research, and outreach activities. 

 

Pouria's service credits include two years as the first President of UA's SPIE student chapter, two turns as OSC's student representative at SPIE conferences, and service as a lecturer in Arizona Youth University's Optical Sciences Summer Camp.  His list of honors and awards includes a First Prize Award at UA's Student Showcase in November 2006, a UA Super Achiever Graduate Student Certificate in all-around activities in August, 2006, and an SPIE Educational Scholarship, also in August, 2006.

 

The Optical Sciences Outstanding Graduate Student Award is new this year and Pouria is the first student to receive it.

 

Congratulations, Pouria.

 

Jae Hoon Lee
Receives the 2006-2007
Christopher Karl Schultz Memorial Scholarship

 

Jae Hoon's outstanding scholastic ability, along with his theoretical and experimental research work, demonstrate the research promise in applied optics that is the spirit of this award. 

 

The Scholarship was established by the family, friends, and colleagues of Christopher Karl Schultz, a gifted OSC graduate student who valued academic and research excellence.  The scholarship recipient is always a second-year Optical Sciences PhD student with outstanding scholastic ability and research promise in applied optics. 

 

Jae Hoon joins an elite list of Scholarship recipients:  Garrett Bonnema in 2004-2005, Nathan Hagen in 2003-2004, and Christopher DeRose in 2002-2003.

T-Shirts on Display

Vote (early and often) for Your Favorite T-Shirt Design

 

From Corrie Vandervlugt.  OSC, It's that time again... time to decide which T-shirt design will be triumphant and which ones will get tossed by the wayside (in other words get tossed in a folder marked "old designs" only to be forgotten).  It is all up to you; your vote could be the deciding factor.  

 

We have a total of 14 incredible designs to choose from, and they will be on display starting today on the 5th floor bulletin board—near the breezeway between the West Wing and the Old Building.  Note, this is a change from the hall by the library. 

 

Voting will commence Friday March 23rd at the opening of the Academic Programs Office, Room 403.  Voting will be done by ballots, and the ballot box is located in the Academic Programs Office.  Voting will end promptly at 5pm.  At this point, a number of trusted agents will count the votes and the most popular design will be declared winner. 

 

Good luck to all designs and please remember to vote on Friday!
