Title: Adventures in interferometric metrology

Location: Information Technologies Engineering

ITEB Room 336

Thursday May 7, 2015

Speaker: Dr. Peter J. de Groot

Host: Prof. Bahram Javidi

Sponsored by SPIE and OSA Uconn chapter

Abstract

Light travels incredibly fast, has a wavelength of less than a thousandth of a millimeter

in the visible, and oscillates at 600 THz—far too fast to be detected directly the way that

we detect radio waves or sound waves. Miraculously, we can access the wavelength and

use it as a precise unit of measurement, by taking advantage of the principle of

superposition: Two light waves can coexist in the same space, and when they do, they

interfere with each other. The effect is linear in complex amplitude (well, most of the

time), which is mathematically lovely. If the two waves are close in frequency, it is easy

to observe the interference fringe patterns and use the very small wavelength for high-

precision metrology. I always delight in the appearance of interference fringes not only

for the remarkable physics that they reveal, but also for their practical value—I have

made use of this effect to solve problems in optical metrology and instrument design.

This presentation will provide illustrative examples of such practical interferometry,

including precision stage motion control, the testing of lenses and mirrors,

semiconductor wafer metrology, the detailed analysis of microscopic surface structure,

and life science applications.

Title: Tomographical wavefront restoration using lightfield

acquisition.

Location: Information Technologies Engineering

ITEB Room 401A

Wednesday, August 26, 2015

Speaker: José Manuel Rodríguez Ramos

Host: Prof. Bahram Javidi

Sponsored by SPIE and OSA Uconn chapter

Abstract:

Lightfield acquisition is a well-known technique to capture the entire optical

information from a scene. We use information from the light field to obtain a distribution

map of the wavefront phase. This distribution is associated with changes in refractive

index which are relevant in that are caused by the propagation of light through a

heterogeneous or turbulent medium.

Wavefront recovery is not limited to a single layer but it is also possible to recover

tomographic information of wavefront using, for instance, one plenoptic sensor to

acquire the lightfield.

This technique can be applied to transparent objects in microscopy, for adaptive optics

correction in Astronomy, etc.

Title: Photoacoustic sensor for concurrent opto-mechanical

microfluidic sensing

Location: Information Technologies Engineering

Abstract

While there are a large number of reports on acoustic wave based sensors for evaluating

mechanical parameters of fluid samples such as density, viscosity etc., devices for the

simultaneous optical and mechanical characterization of fluids remain unexplored. In

this context, effective utilization of surface acoustic wave (SAW) sensors comprising

elliptically polarized evanescent waves for optical characterization of an analyte is

intriguing. A combination of SAW and photoacoustic (PA) techniques presents

promising capabilities for optical and mechanical characterization of fluids in micro

volumes. We present a SAW-PA integrated device combining PA and SAW where the

samples are introduced into a microfluidic channel. The PA signal generated from a

sample in the microchannel of the SAW-PA device is mode-converted into SAW signals

upon reaching the piezoelectric substrate, which is detected using the inter-digital

transducer (IDT) deposited on the substrate. We further demonstrate the use of this

SAW-PA compact platform for investigating the opto-acoustical properties of standard

dye solutions and gold nanoparticles whose absorption is due to plasmonic resonance.

Title: Single-pixel imaging by means of Fourier spectrum acquisition

Location: Information Technologies Engineering

ITEB Room 301

October 20 2016, Thursday, 12:00 PM –2:00 PM.

Host: Hamed Vavadi/ Mohsen Erfanzadeh

Sponsored by SPIE and OSA UConn chapter

Abstract:

Single-pixel imaging techniques enable to capture a scene without a direct line of sight

to the object, but high-quality imaging has been proven challenging especially in the

presence of noisy environmental illumination. Here we present a single-pixel imaging

technique that can achieve high-quality images by acquiring their Fourier spectrum. We

use phase-shifting sinusoid structured illumination for the spectrum acquisition.

Applying inverse Fourier transform to the obtained spectrum yields the desired image.

The proposed technique is capable of capturing a scene without a direct view of it. Thus,

it enables a feasible placement of detectors, only if the detectors can collect the light

signals from the scene. The technique is also a compressive sampling like approach, so

it can reconstruct an image from sub-Nyquist measurements. We experimentally obtain

clear images by utilizing a detector not placed in direct view of the imaged scene even

with noise introduced by environmental illuminations.
