Miniaturized computational spectrometers have emerged as a promising strategy for
miniaturized spectrometers, which breaks the compromise between footprint and …

Although multispectral imaging (MSI) of cultural heritage, such as manuscripts, documents
and artwork, is becoming more popular, a variety of approaches are taken and methods are …

We propose a spectral imaging method that allows a regular digital camera to be converted
into a snapshot spectral imager by equip** the camera with a dispersive diffuser and with …

Liquid crystal tunable filters (LCTF) are extensively used in hyperspectral imaging systems
to successively acquire different spectral components of scenes by adjusting the center …

This paper presents the methodology to design and integrate a liquid crystal tunable filter
(LCTF) based shortwave infrared (SWIR) spectral imaging system. The system consisted of …

Coded apertures with random patterns are extensively used in compressive spectral
imagers to sample the incident scene in the image plane. Random samplings, however, are …

We propose a snapshot spectral imaging method for the visible spectral range using two
digital cameras placed side-by-side: a regular red–green–blue (RGB) camera and a …

This paper proposes a spectral imaging technology by synchronizing a programmable light
source and a high-speed monochrome camera. The light source is capable of emitting …

This study analyzes the repeatability, reproducibility and accuracy of a new hyperspectral
system based on a pushbroom sensor as a means of measuring spectral features and color …

In this paper, we present a method for hyperspectral retrieval using multispectral satellite
images. The method consists of the use of training spectral data with a compressive …
