Abstract

A laser observation space instrument for the quantitative characterization by DOPPLER effect of movements within a fluid mass carried by a planet having a reference axis locally parallel to its trajectory and including a laser generator, a frequency measuring unit, first and second sighting elements aligned on the reference axis and having first and second lines of sight of non-null inclinations with respect to the reference axis and intended for emitting and receiving laser beams, a single telescope with its axis merged with the reference axis in order to send beams emitted by the laser generator to the sighting elements and to apply laser beams received by these sighting elements to the measuring unit, and rotating means for rotating the sighting elements with respect to the panel about the reference axis. The first sighting element, disposed between the telescope and the second sighting element, is adapted to transmit, to the second sighting element, along the reference axis, laser beams sent by the telescope, and vice versa.
