Fast Inline Microscopic Computational Imaging

open access: yesSensors, 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 ...

Optimal Stellar Photometry for Multi-conjugate Adaptive Optics Systems Using Science-based Metrics [PDF]

open access: yes, 2016
We present a detailed discussion of how to obtain precise stellar photometry in crowded fields using images from multi-conjugate adaptive optics (MCAO) systems, with the intent of informing the scientific development of this key technology for the ...

JWST Observations of the Enigmatic Y-Dwarf WISE 1828+2650. I. Limits to a Binary Companion

open access: yesThe 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 ...

PROBABILITY OF THE PHYSICAL ASSOCIATION OF 104 BLENDED COMPANIONS TO KEPLER OBJECTS OF INTEREST USING VISIBLE AND NEAR-INFRARED ADAPTIVE OPTICS PHOTOMETRY [PDF]

open access: yes, 2016
We determine probabilities of physical association for stars in blended Kepler Objects of Interest (KOIs), and find that of companions within ∼4″ are consistent with being physically unassociated with their primary.

Modeling and Analysis of an Echo Laser Pulse Waveform for the Orientation Determination of Space Debris

open access: yesRemote Sensing, 2020
Orientation information of space debris is required to improve the orbital prediction accuracy for mitigation or elimination of a significant threat to not only human space activities but also operational satellites.

Accurate Photometry of Saturated Stars Using the Point-spread-function Wing Technique with Spitzer [PDF]

open access: yesAstronomical Journal, 2021
We report Spitzer 3.6 and 4.5 μm photometry of 11 bright stars relative to Sirius, exploiting the unique optical stability of the Spitzer Space Telescope point-spread function (PSF).
