Laser metrology: new generation of MOUSE sensors extends distance and displacement

Autor: B. Liagre, Laurence Pujol, O. Gry, Anne Poupinet, J. M. Le Duigou, J. Berthon

Publikováno v: International Conference on Space Optics — ICSO 2004.

In the frame of the CNES R and T activity related to laser metrology, SAGEIS-CSO is actually developing a new smart interferometric sensor, last to arrive in the “MOUSE” family. In this article, we give at first a brief oversight of the MOUSE int

Publikováno v: International Conference on Space Optics — ICSO 2006.

In the context of formation flying projects, one of the major points is the required precision on the intersatellites distance and/or relative displacement. According to the mission, these needs are more or less restrictive, leading to the use of fin

Publikováno v: International Conference on Space Optics — ICSO 2008.

Nulling interferometry is one of the direct detection methods assessed to find and characterize extrasolar planets and particularly telluric ones. Several projects such as Darwin [1;2], TPF-I [3;4], PEGASE [5;6] or FKSI [7], are currently considered.
