Application of confocal surface wave microscope to self-calibrated attenuation coefficient measurement by Goos-Hänchen phase shift modulation (2018)
Journal Article

In this paper, we present a direct method to measure surface wave attenuation arising from both ohmic and coupling losses using our recently developed phase spatial light modulator (phase-SLM) based confocal surface plasmon microscope. The measuremen... Read More about Application of confocal surface wave microscope to self-calibrated attenuation coefficient measurement by Goos-Hänchen phase shift modulation.

Analysis of noise in differential and ratiometric biosensing systems (2018)
Journal Article

This paper presents formulations to evaluate noise in differential and ratiometric measurements that are often performed in biosensing. These measurements are performed to improve signal to noise ratio of the sensing systems for sensitive detection o...

Sensitive detection of voltage transients using differential intensity surface plasmon resonance system (2017)
Journal Article

This paper describes theoretical and experimental study of the fundamentals of using surface plasmon resonance (SPR) for label-free detection of voltage. Plasmonic voltage sensing relies on the capacitive properties of metal-electrolyte interface tha...

Sub-100 nm resolution microscopy based on proximity projection grating scheme (2015)
Journal Article

Structured illumination microscopy (SIM) has been widely used in life science imaging applications. The maximum resolution improvement of SIM, compared to conventional bright field system is a factor of 2. Here we present an approach to structured il...

Ultrastable embedded surface plasmon confocal interferometry (2014)
Journal Article

As disease diagnosis becomes more sophisticated, there is a requirement to measure small numbers of molecules attached to, for instance, an antibody. This requires a sensor capable not only of high sensitivity but also the ability to make measurement... Read More about Ultrastable embedded surface plasmon confocal interferometry.

Surface plasmon microscopic sensing with beam profile modulation (2012)
Journal Article

Surface Plasmon microscopy enables measurement of local refractive index on a far finer scale than prism based systems. An interferometric or confocal system gives the so-called V(z) curve when the sample is scanned axially, which gives a measure of...

Determination of crystallographic orientation of large grain metals with surface acoustic waves (2012)
Journal Article

A previously described laser ultrasonic technique known as spatially resolved acoustic spectroscopy (SRAS) can be used to image surface microstructure, using the local surface acoustic wave (SAW) velocity as a contrast mechanism. It is shown here tha... Read More about Determination of crystallographic orientation of large grain metals with surface acoustic waves.

Confocal surface plasmon microscopy with pupil function engineering (2012)
Journal Article

Surface Plasmon microscopy can measure local changes of refractive index on the micron scale. Interferometric plasmon imaging delivers quantitative high spatial resolution sensitive to refractive index. In addition the so called V(z) method allows im...

CHOTs optical transducers (2011)
Journal Article

Laser ultrasonics conventionally use direct absorption in the sample to generate ultrasound and monitor the sample to detect the ultrasound. However, in some circumstances there are significant advantages to using an optical transducer - a device to... Read More about CHOTs optical transducers.

The Design of a Real Time VLSI Optical Centroid Processor (2002)
Conference Proceeding

A real time VLSI optical centroid processor has been developed as part of a larger Shack-Hartmann wavefront sensor system for applications in adaptive optics. The implementation of the optical centroid detection system was demonstrated successfully u... Read More about The Design of a Real Time VLSI Optical Centroid Processor.
