An E-ELT Case Study: Colour-Magnitude Diagrams of an Old Galaxy in the Virgo Cluster [PDF]
SPIE Proceedings, 2011 One of the key science goals for a diffraction limited imager on an Extremely Large Telescope (ELT) is the resolution of individual stars down to faint limits in distant galaxies.

Influence of Mie scattering on nanoparticles with different particle sizes and shapes: photometry and analytical ultracentrifugation with absorption optics [PDF]
Journal of the Serbian Chemical Society, 2005 Nanoparticles are used in large quantities for very different applications. A precise determination of the diameter and the particle size distribution which is responsible for the application properties is therefore essential.

Macular pigment optical density measured by heterochromatic modulation photometry. [PDF]
PLoS ONE, 2014 PURPOSE:To psychophysically determine macular pigment optical density (MPOD) employing the heterochromatic modulation photometry (HMP) paradigm by estimating 460 nm absorption at central and peripheral retinal locations. METHODS:For the HMP measurements,

Fast Inline Microscopic Computational Imaging
Sensors, 2022 Inline inspection is becoming an essential tool for industrial high-quality production. Unfortunately, the desired acquisition speeds and needs for high-precision imaging are often at the limit of what is physically possible, such as a large field of ...

JWST Observations of the Enigmatic Y-Dwarf WISE 1828+2650. I. Limits to a Binary Companion
The Astrophysical Journal, 2023 The Y-dwarf WISE 1828+2650 is one of the coldest known brown dwarfs with an effective temperature of ∼300 K. Located at a distance of just 10 pc, previous model-based estimates suggest WISE1828+2650 has a mass of ∼5–10 M _J , making it a valuable ...

Reference-less detection, astrometry, and photometry of faint companions with adaptive optics [PDF]
, 2009 We propose a complete framework for the detection, astrometry, and photometry of faint companions from a sequence of adaptive optics corrected short exposures. The algorithms exploit the difference in statistics between the on-axis and off-axis intensity.
