Depth Profilometry involves the measurement of the depth profile of objects, and has significant potential for various industrial applications that benefit from non-destructive sub-surface profiling such as defect detection, corrosion assessment, and

In this paper, we present a spectral parallelism electronic system that works as a data acquisition and image reconstruction system for magnetic resonance imaging (MRI). It uses a custom receiver chain and narrowband bandpass filters. The broadband m

Hyperspectral imaging (HSI) device users often require both high spectral resolution, on the order of 1 nm, and high light-gathering power. A wide entrance slit assures reasonable etendue but degrades spectral resolution. Spectrometers built using Hi

Many DMD-based programmable light sources consist of a white light source and a pair of spectrometers operating in subtractive mode. A DMD between the two spectrometers shapes the delivered spectrum. Since both spectrometers must (1) fit within a sma

We present an atlas of Hubble Space Telescope images and ground-based, long-slit, narrowband spectra centered on the 6584 Angstrom line of [N ii] and the 5007 Angstrom line of [O iii]. The spectra were obtained for a variety of slit positions across

A sequence of integers { n i : i = 0, 1…} is an exhaustive weakly wandering sequence for a transformation T if for some measurable set W, X =⋃ ∞ i =0 T ni W ( disj . We introduce a hereditary Property (H) for a sequence of integers associated w

Photonics is an inherently interdisciplinary endeavor, as technologies and techniques invented or developed in one scientific field are often found to be applicable to other fields or disciplines. We present two case studies in which optical spectros
