Formation of oxygen vacancies and Ti3+ state in TiO2 thin film and enhanced optical properties by air plasma treatment
This is the first time we report that simply air plasma treatment can also enhances the optical absorbance and absorption region of titanium oxide (TiO2) films, while keeping them transparent. TiO2… Expand

On the estimation of target spectrum for filter-array based spectrometers.
TLDR
In this paper, we show the achievability of a fine spectrometer on-a-chip based on a low-performance, low-cost filter-array. Expand

An Information-Theoretic Study for Joint Sparsity Pattern Recovery With Different Sensing Matrices
TLDR
In this paper, we study a support set reconstruction problem for multiple measurement vectors (MMV) with different sensing matrices, where the signals of interest are assumed to be jointly sparse and each signal is sampled by its own sensing matrix in the presence of noise. Expand

Improving resolution of miniature spectrometers by exploiting sparse nature of signals.
In this paper, we present a signal processing approach to improve the resolution of a spectrometer with a fixed number of low-cost, non-ideal filters. We aim to show that the resolution can be… Expand
