Detection of Solar Prominences using Automated Methods and Analysis of their Dynamic Pre-Eruptive Behaviour
… the second event, we develop and apply automated detection methods for EUV prominences observed by the twin spacecraft from the Solar Terrestrial Relations Observatory (STEREO) mission and the Solar Dynamics Observatory (SDO) near Earth. During March 2011, when each STEREO spacecraft is in …

Humidity sensing by optically interfacing with spectrally absorptive materials
… has an insertion loss of less than 0.2 dB. Two-wavelength detection is employed to provide referencing to eliminate common mode intensity variation. The basic design, construction and testing of an experimental sensor in the humidity region 20 to 80% RH and temperature range 25 to 50 °C is …

Guided -Mode Resonance in Planar Photonic Crystals: Application to Sensing
… the guided-mode resonance effect for sensing and detection applications. A theoretical basis for these applications is first developed, followed by the demonstration of a near-ultraviolet reflectance filter that provides high reflection efficiency in the 400-450 nm spectral range. The response of …

Advanced silicon photonic microcavities for routing, detection and lasing applications
… These structures provide the ability to filter wavelength, support high-Q modes and enhance intensity within the cavities while maintaining a small device footprint. Such characteristics make these structures good candidates to optimize performance and shrink the size of devices for both linear …

Vortex Light Field Microscopy for 3D Spectral Single-Molecule Imaging
… imaging, most of which either achieve continuous wavelength detection with a shallow axial range, or extended depth at several discrete wavelengths. Therefore, to address the need of a method for continuous spectral measurement with large axial range, we developed vortex light field microscopy …

Visible and Infrared Light Detection Using 2D Materials
… solar cell applications. With respect to longer wavelength detection, application of 2D crystals and other ultrathin materials such as ALD grown Hafnium Zirconium Oxide (Hf₀.₅Zr₀.₅O₂) open up the possibility of designing fast (<1 ms thermal time constant) thermal detectors while still maintaining …

Detectability of biosignature gases in the atmospheres of terrestrial exoplanets
… molecules provide the best opportunities for detection grows as well. One way to explore these systems is through modeling radiative transfer via transmissivity as light travels from the parent star, through the atmosphere of the planet, and then impacts a detector located at Earth. As the …
