C-RED One : The InfraRed Camera using the Saphira e-APD detector

June 2016 (9907-86 SPIE Astronomical Telescopes and Instrumentation)

 

Abstract: First Light Imaging’s C-RED One infrared camera is capable of capturing up to 3500 full frames per second with a subelectron readout noise and very low background. This breakthrough has been made possible thanks to the use of an e-APD infrared focal plane array which is a real disruptive technology in imagery. C-RED One is an autonomous system with an integrated cooling system and a vacuum regeneration system. It operates its sensor with a wide variety of read out techniques and processes video on-board thanks to an FPGA.

Fast sub-electron detectors review for interferometry

June 2016 (9907-39 SPIE Astronomical Telescopes and Instrumentation)

 

Abstract: New disruptive technologies are now emerging for detectors dedicated to interferometry. The detectors needed for this kind of applications need antonymic characteristics: the detector noise must be very low, especially when the signal is dispersed but at the same time must also sample the fast temporal characteristics of the signal. This paper describes the new fast low noise technologies that have been recently developed for interferometry and adaptive optics.

OCAM2S: an integral shutter ultrafast and low noise wavefront sensor camera for laser guide stars adaptive optics systems (Preprints of the AO4ELT4 proceedings (Lake Arrowhead 2015)

 

October 2015

To date, the OCAM2 system has demonstrated to be the fastest and lowest noise production ready wavefront sensor, achieving 2067 full frames per second with subelectron readout noise. This makes OCAM2 the ideal system for natural as well as continuous wave laser guide star wavefront sensing. In this paper we present the new gated version of OCAM2 named OCAM2-S, using E2V’s CCD219 sensor with integral shutter…

State of the art IR cameras for wavefront sensing using e-APD MCT arrays (Preprints of the AO4ELT4 proceedings (Lake Arrowhead 2015)

October 2015

The recent discovery of electron initiated avalanche photodiodes (e-APDs) using mercury cadmium telluride semiconductor materials has permitted a significant advance in short-wave infrared imaging. In the visible spectrum, electron-multiplying charge-coupled devices (EMCCDs) improved imaging techniques—especially in the life sciences. And yet, no significant breakthroughs have been made in infrared imagery since the hybridization of III-V or II-VI semiconductors with low bandgap on complementary metal-oxide semiconductor (CMOS) read-out integrated circuits (ROICs)…

High speed and High precision pyramid wavefront sensor. In labs validation and preparation to on sky demonstration – Hacem El Hadi reports on his work with OCAM²

2014

Abstract. Since the introduction of the pyramid wavefront sensor [P-WFS] concept (Ragazzoni), numerous investigations have clearly shown its ability to achieve better performance (sensitivity, dynamic range) than the standard Shack-Hartman [SH-WFS]. It has recently been successfully implemented on LBT and has already been provided very interesting results (Esposito et al). Then, most of the future adaptive optics [AO] systems, mainly for ELT instrumentation, will probably integrate one or several pyramidal sensors…

DEVELOPMENT OF A PYRAMID WAVEFRONT SENSOR

May 2013

Abstract. Within the framework of the E-ELT studies, several laboratories are involved on some instruments:
ARMONI with its ATLAS adaptive optics [AO] system, EAGLE or EPICS. Most of the AO systems will probably integrate one or several  pyramidal wavefront sensors, PWFS (R. Ragazzoni [1-2]). The coupling in an AO loop and the control in laboratory (then on sky) of this type of sensor is fundamental for the continuation of the projects related to OA systems on the E-ELT…
