CEDRAT TECHNOLOGIES Innovation in Mechatronics compact dynamic precise Fine & fast steering mirrors (FSM) - Heritage in aerospace & defence 1. PHARAO DOUBLE TIP TILT (DTT) 1.1. DESCRIPTION The Double Tip Tilt mechanism DTT35 XS-space delivered to SODERN (AIRBUS) is a very light piezoelectric mechanism (25 grams) designed according to space rules for the PHARAO ACES mission. The mechanism uses Strain Gauges (SG) as positioning sensor and allows to reach a 1:4000 stability (1 μrad rms). It controls the incidence of a laser beam flux towards an optical fiber Compact FSM with its controller box...

CEDRAT TECHNOLOGIES Innovation in Mechatronics compact dynamic precise Fine & fast steering mirrors (FSM) - Heritage in aerospace & defence Thanks to the heritage from the PHARAO DTT, CTEC has developed the ATLID Beam Steering Mechanism (BSM) for SODERN (see publication). ATLID is a Lidar instrument for the EarthCARE mission. The BSM is a Tip-Tilt piezo mechanism based on 4 APAs including Strain Gauges. The requirements were particularly severe regarding the long term stability and the cleanliness. CTEC has successfully delivered the Flight Models in 2015 The BSA (Beam Steering Assembly),...
