Physics Department Colloquium/Seminar

Schedule:

** November 6, 2009, FRIDAY  (SPECIAL DATE)**
Time: Noon-1 pm with 11:30 am tea time

**ROOM: 202 ECE **

Nonlinear Optical Tissue Imaging

Prof. Feruz Ganikhanov
West Virginia University
(Optics/Biophysics, Host: Thomas)

Abstract

Applications of nonlinear optical techniques that help to characterize live tissue with 250 nm spatial resolution will be presented. In particular, recent results on multimodal nonlinear optical imaging of fascia, a rich collagen type-I sheath around internal organs and muscle will be discussed. I will also present results on axon imaging of the peripheral nervous system using combined microscopy techniques and most recent results on resolving sarcomere structures within the skeletal muscle using Coherent Anti-Stokes Raman Scattering microscopy. Issues related to complementary information that can be obtained using four different nonlinear optical techniques will be discussed along with currently pursued instrument designs and experimental solutions that will help to find applications of nonlinear optics in biology and medicine.

"Terahertz imaging and spectroscopy for detection of concealed weapons, explosives and drugs"

Abstract

It is well-known that terahertz radiation, which covers the electromagnetic spectrum from roughly 300GHz-5THz, shows great promise as a means to detect concealed objects. THz radiation can propagate through most non-metallic and non-aqueous materials including clothing, postal packaging, plastics, etc.

Many explosives, including improvised explosive devices, exhibit characteristic THz 'colors' in both transmission and reflection. An overview of THz imaging and spectroscopy will be presented with emphasis on detection of concealed weapons, explosives, and drugs.
