How to Interpret Images From Infrared CamerasA field campaign. A laboratory testbed. A volcano. Different applications of infrared cameras, but the very same modus operandi. Turn the camera on, point it toward the scene, and get images on the screen. It looks so simple! And the image is even calibrated in real temperature units. Great!
Real life conditions are unfortunately a bit more complex. Accurate interpretation of the infra...

Radiometry – The basicsWhat is radiometry? The etymology of radiometry links to “radiation” and “measurement”. More precisely, radiometry is the science studying the transport of energy through radiation.
The present document aims at presenting a summary of the principal laws of radiometry involved in the understanding of the world surrounding us, as seen through light-sensitive instruments! Among these are ...

ARIADNE+: Large Scale Demonstration of Fast Optical Readout for Dual-Phase LArTPCs at the CERN Neutrino PlatformOptical readout of large scale dual-phase liquid Argon TPCs is an attractive alternative to charge readout and has been successfully demonstrated on a 2 × 2 m active region within the CERN protoDUNE cold box. ARIADNE+ uses four Timepix3 cameras imaging the S2 light produced by 16 novel, patent pending, glass THGEMs.

First demonstration of 3D optical readout of a TPC using a single photon sensitive Timepix3 based cameraThe ARIADNE project is developing innovative optical readout technologies for two-phase liquid Argon time projection chambers (LArTPCs). Optical readout presents an exciting alternative to the current paradigm of charge readout. Optical readout is simple, scalable and cost effective. This paper presents first demonstration of 3D optical readout of TPC, using CF4 gas as a proof of principle.

Observation of Nonclassical Photon Statistics in Single-Bubble SonoluminescenceA cavitation bubble inside a liquid, under a specific set of conditions, can get trapped in an antinode of the ultrasonically driven standing wave and periodically emits visible photons (1,2). This conversion of sound to light phenomenon, known as sonoluminescence, can be seen with unaided eyes and occurs in multi- or single-bubble regimes. The sonoluminescence radiation spectrum analysis at...

High speed imaging of spectral-temporal correlations in Hong-Ou-Mandel interferenceIn this work we demonstrate spectral-temporal correlation measurements of the Hong-Ou-Mandel (HOM) interference effect with the use of a spectrometer based on a photon-counting camera. This setup allows us to take, within seconds, spectral temporal correlation measurements on entangled photon sources with sub-nanometer spectral resolution and nanosecond timing resolution.
