UR SPIE Colloquium Summer Series

Close

July 1, 2014

On Tuesday, July 1st the UR SPIE student chapter will be continuing its Summer Colloquium series. Please bring your lunch and come listen to our next presentation! Snacks and beverages will be provided.

Who: Patrice Tankam
What: Multiple-Wavelength Digital Holography and Applications
Date: 7/1/2014
Time: 11:30 am - 12:30 pm
Where: Sloan Auditorium (Goergen 101)
Abstract: Since its discovery in 1947 by Denis Gabor, Holography was shown to be a powerful tool to perform “real” 3D imaging and optical metrology. The development of high-resolution CCDs and powerful processors during the last decades opened new opportunities to apply digital holography in different domains. Digital holography combines the interferometric recording of the light scattered from the object and the back-propagation computation of the interference pattern to retrieve the 3D information of the object. Most of the recent developments and accomplishments in digital holography were based on a single-wavelength configuration. However, a multiple-wavelength is necessary to obtain the true color of the object or the absolute value of the measurement. This presentation will focus on my contribution in multiple-wavelength digital holography applied in several projects (aerodynamic flow visualization, mechanics, electronics, etc).

Who: Steve Head
What: Arbitrary Spatially-Varying Polarization State Generator for Deep Sub-Wavelength Metrology​
Date: 7/8/2014
Time: 11:30 am – 12:30 pm
Where: Sloan Auditorium (Goergen 101)
Abstract: The lithography industry makes use of a wide array of tools for metrology of their nano-scale structures. Scatterometry is one such method in which the scattered light from a periodic test structure is compared with theoretical results from Rigorous Coupled Wave Analysis in order to back-out structure parameters such as critical dimension, film thicknesses, and sidewall angle. Current scatterometry methods could possibly be improved by using a focused beam to acquire angular scatter information in a single measurement and by tailoring the input polarization to make the output more sensitive to small deviations. This talk will focus on the polarization generator I helped build and how it can be used to maximize the ability of a scatterometry system to back-out structure parameters.

                   Who: Robin Sharma
                   What: Two-photon fluorescence imaging of the retina in the living eye using adaptive optics
                   Date: 7/15/2014
                   Time: 11:30 am – 12:30 pm
                   Where: Sloan Auditorium (Goergen 101)
Abstract: Adaptive optics scanning laser ophthalmoscopy (AOSLO) permits diffraction-limited imaging of microscopic structures in the retina in living eyes. Thanks to various advances in system design and image registration software, functional imaging of different cell classes in the retina is within reach. Two-photon fluorescence imaging has a number of advantages for retinal imaging. All cells in the retina fluoresce with appropriate infrared two-photon excitation, offering the possibility of imaging every class of retinal cell, even those that are transparent in visible light. It also allows the study of molecular species whose excitation regime is in the ultraviolet, a region of the spectrum that is inaccessible in reflectance and single photon fluorescence imaging because it lies outside the transmittance spectrum of the ocular media. Additionally, it allows functional as well as structural imaging by monitoring molecular changes that are invisible with conventional imaging methods. A two-photon adaptive optics scanning light ophthalmoscope has been developed for imaging living, anaesthetized primates. An ultrashort pulsed laser (~ 55 fs pulse-width) with a tunable central wavelength was used to excite two-photon fluorescence. Consistent with measurements made in excised retina, fluorescence emission was detected throughout the retina in vivo although the strongest autofluorescence signal originated from near the photoreceptor layer. Two-photon images of individual cells and other recognizable structures were obtained in multiple retinal layers such as the nerve fiber layer, individual rods as well as cones and retinal pigment epithelial cells. Also, the time-course of fluorescence from individual photoreceptor cells provides clues about the molecules that might be responsible for this autofluorescence. This is an important step towards noninvasively monitoring functional activity in individual retinal layers.

Variation Seen in Walking Patterns of a Healthy Population and the Impact of Data Collection Methods on Uncertainty and Cost of Biomechanical Modeling

 by Molly Zapkin

Co-supervised by:  Prof. Amy Lerner and Prof. Paul Funkenbusch

2:00 pm

River Campus

Hopeman Bldg., Room 224

 Abstract

Biomechanical models are often used in research to simulate complex situations that may be difficult to capture in an in-vivo setting. The two goals of this research were (1) to identify the variability in the walking patterns seen within and between subjects during normal walking and (2) to develop a methodology that can be applied to any type of model that allows the researcher to assess the model uncertainty in relation to the cost of data collection.  Intra-class correlation coefficients and 95% bootstrap confidence intervals were used to assess the intra and inter subject variability, respectively.  The variability analysis provides results that can be used when developing gait data collection protocols to obtain necessary model inputs. The methodology for assessing the uncertainty in the model provides researchers with a way to justify how they utilize their resources in terms of data collection.
