The ANITA2 (Analysing Interferometer for Ambient Air) instrument is a trace gas analyser, designed to operate onboard the ISS and to monitor the cabin atmosphere. Within the last 2 years, significant progress has been made towards realizing the flight instrument, including the flight-like design, ma...

ANITA2 (Analysing Interferometer for Ambient Air) follows the European precursor mission ANITA1, which delivered information on the air conditions analysing in parallel 33 of the most important trace gases on-board ISS in the cabin atmosphere in 2007 and 2008. The data have shown the benefits of in-...

This paper describes a 3D measurement algorithm based on Multi-Frequency Phase Stepping, using a single period pattern and a higher frequency pattern. An experimentally verified analytical expression for depth precision enables adaptive selection of the high frequency. The algorithm has several adva...

High-quality video observations are very much needed in underwater environments for the monitoring of several ecosystem indicators and to support the sustainable development and management of almost all activities in the ocean. Reliable video observations are however challenging to collect, because ...

We present a range-gated camera system designed for real-time (10 Hz) 3D estimation underwater. The system uses a fast-shutter CMOS sensor (1280×1024 1280×1024 ) customized to facilitate gating with 1.67 ns (18.8 cm in water) delay steps relative to the triggering of a solid-state actively...

In this article the development of a newly designed Time-of-Flight (ToF) image sensor for underwater applications is described. The sensor is developed as part of the project UTOFIA (underwater time-of-flight image acquisition) funded by the EU within the Horizon 2020 framework. This project aims to...
