Son of X–Shooter: a multi–band instrument for a multi–band universe [PDF]
Proceedings of Frontier Research in Astrophysics – III — PoS(FRAPWS2018), 2018 Son Of X-Shooter (SOXS) will be a new instrument designed to be mounted at the Nasmyth–A focus of the ESO 3.5 m New Technology Telescope in La Silla site (Chile). SOXS is composed of two high-efficiency spectrographs with a resolution slit product 4500, working in the visible (350 - 850 nm) and NIR (800 - 2000 nm) range respectively, and a light imager

Synthesis of multi‐band filters based on multi‐prototype transformation
IET Microwaves, Antennas & Propagation, 2021 In this article, a new synthesis method for generalized multi‐band filters has been proposed. Different from the traditional frequency transformation method, which transforms a low‐pass prototype into a multi‐band filter, multiple low‐pass prototypes ...

Journal of Magnetic Resonance, 2015 A useful extension to SWIFT (SWeep Imaging with Fourier Transformation) utilizing sidebands of the excitation pulse is introduced. This MRI method, called Multi-Band-SWIFT, achieves much higher bandwidth than standard SWIFT by using multiple segmented excitations (bands) of the field of view.

Multi-band modelling of appearance [PDF]
Image and Vision Computing, 2003 Earlier work has demonstrated generative models capable of synthesising near photo-realistic grey-scale images of objects. These models have been augmented with colour information, and recently with edge information. This paper extends the active appearance model framework by modelling the appearance of both derived feature bands and an intensity band.
