Single-pixel camera imaging is an emerging paradigm that allows high-quality images to be provided by a device only equipped with a single point detector. A single-pixel camera is an experimental setup able to measure the inner product of the scene under view—the image—with any user-defined pattern. Postprocessing a sequence of point measurements obtained with different patterns permits to recover...
Single pixel imaging opened the door to a cheaper camera architecture able to operate in a wide spectral range. Such an optical setup has been used with compressed sensing to reconstruct an image via ℓ1-minimization ruling out real time applications. In order to have a direct restoration of the image, we consider an adaptive approach for which we propose a new acquisition strategy. Our method progressively...

Supercontinuum generation from visible up to 2.8 µm is demonstrated in a highly nonlinear heavy metal oxide glass photonic crystal fiber. Numerical modelling suggests that the supercontinuum can be extended to 4 µm.
Mid-IR supercontinuum is demonstrated in a step index fluorozirconate glass fiber pumped by a CPA system emitting 500 fs pulses at 1.6 μm. Output power up to 60 mW is obtained over the supercontinuum bandwidth.
