Phase effects in guided mode resonances II: measuring the angular phase of a surface plasmon polariton

Autor: Thomas G. Brown, Michael J. Theisen

Publikováno v: Journal of Modern Optics. 62:236-243

We show how the phase of a resonant interaction between a focused beam and a guided mode can be directly observed in a pupil imaging experiment, in which the irradiance leaving the pupil of a standard microscope is relayed to an image sensor through

Phase effects in guided mode resonances III: parametric analysis and Fano resonances

Autor: Thomas G. Brown, Michael J. Theisen

Publikováno v: Journal of Modern Optics. 62:244-250

A parametric plot of the complex reflectivity of a Fano-type guided-mode resonance shows a geometric structure that reveals features of the resonance that are not obvious from conventional reflectance or transmittance measurements. To illustrate this

Phase effects in guided mode resonances: spectral phase

Autor: Michael J. Theisen, Thomas G. Brown

Publikováno v: Journal of Modern Optics. 62:229-235

When a suitably designed waveguide grating couples an external wave to a local wave, a well-known (and well-studied) resonance anomaly can appear in the reflectance spectrum. We employ a guided mode resonance in a silicon-on-insulator waveguide to st

Pulse visibility factor and its impact on infrared search and track systems

Autor: Gerald C. Holst, Gene D. Tener, Ronald G. Driggers, Craig Olson, Heath Gemar, Michael J. Theisen, Steve Butrimas, Carl E. Halford

Publikováno v: Optical Engineering. 58:1

The performance of an infrared search and track (IRST) sensor depends on a large number of variables that are important for determining systems performance. One of the variables is the pulse visibility factor (PVF). The PVF is linearly related to IRS

Validation of infrared sensor model with field-collected imagery of unresolved unmanned aerial vehicle targets

Autor: Michael J. Theisen, David Gaudiosi, David Shelton, Ronald G. Driggers, Drew Manville, Carl E. Halford, Jennifer Hewitt, Teresa Pace, Robert Short, Gene D. Tener, Heath Gemar, Nicolette Fudala, Craig Olson

Publikováno v: Optical Engineering. 58:1

An infrared (IR) sensor model is validated using experimentally derived peak pixel signal-to-noise ratio (SNR) versus range for detection of either an unresolved or a resolved unmanned aerial vehicle (UAV) target. The model provided estimates the tim

Comparison of midwave versus longwave intensity signatures for infrared search and track of small rotorcraft unmanned aerial vehicles

Autor: Carl E. Halford, Nicolette Fudala, Jennifer Hewitt, Ronald G. Driggers, Kathleen Richardson, Chris Fearing, David Gaudiosi, Gene D. Tener, Alex Dapore, Drew Manville, Teresa Pace, Craig Olson, Michael J. Theisen, Robert Short

Publikováno v: Optical Engineering. 58:1

Longwave infrared (LWIR) and midwave infrared (MWIR) UAV signature data have been acquired and analyzed in collaboration with L3 Technologies, and we present intensity and root sum square delta T for two rotorcraft unmanned aerial vehicles (UAVs), in

Model development and system performance optimization for staring infrared search and track (IRST) sensors

Autor: Ronald G. Driggers, Teresa Pace, Carl E. Halford, Craig Olson, Michael J. Theisen

Publikováno v: SPIE Proceedings.

The mission of an Infrared Search and Track (IRST) system is to detect and locate (sometimes called find and fix) enemy aircraft at significant ranges. Two extreme opposite examples of IRST applications are 1) long range offensive aircraft detection
