On behalf of European Space Agency (ESA), Thales Alenia Space, Sintef and Terma are completing a study identifying alternatives to the cameras currently deployed on spacecrafts and space rovers.
In the previous decades, many 2-D cameras have been launched into space. But the new study hopes to identify the most promising 3-D technology for space missions.
French-Italian Thales Alenia Space has has mapped the requirements for the new 3-D camera. Based on these requirements, Sintef has evaluated a wide range of time-of-flight technologies, to determine their relative strengths and weaknesses in such a setting.
"In the course of next year, a prototype breadboard 3-D camera will be built. The next step then will be to test and evaluate the prototype,” says Henrik Schumann-Olsen of Sintef.
The Danish company Terma (Lystrup, Denmark) will build the prototype, which then will be tested and evaluated by ESA and all three companies.
