Some metrological means, such as Shack-Hartmann, deflectometry sensors or fringe projection profilometry, measure the shape of an optical surface indirectly from slope measurements. Zonal shape reconstruction, a method to reconstruct shape with a hig

In the past 20 years, a new generation of telescopes with large primary mirrors has appeared, based on the segmented mirrors design. The Thirty meter Telescope and the European Southern Observatory (ESO) Extremely Large telescope (ELT) are now under

International audience; For a number of optical methods, including deflectometry, information is encoded in fringe patterns. To extract the phase data from intensity values, a number of phase shift algorithms have been designed. In deflectometry, the

The highly aspheric secondary mirror M2 of ESO’s Extremely Large Telescope (ELT) is the largest convex mirror ever polished. We report on manufacturing and error analysis of the high accuracy computer-generated hologram (CGH) used as part of the te

Safran Reosc has been awarded by ESO the manufacturing of the Secondary Mirror of the Extremely Large Telescope in 2016 [4]. The secondary mirror is a 4-meter convex mirror, the world’s largest convex precision mirror ever made. We present the main

The introduction of freefrom optical surfaces in a space instrument offers the possibility to improve its performance, its volume and weight or a combination of both. This is shown to be valid for either imaging systems or spectroscopic systems. At S

SFIM Industries has designed a new radiometer for satellite observation of the earth radiation budget at the top of the atmosphere. COmpared to previous instruments, this new radiometer halves costs, mass and probability of failure, while it improves

In order to simplify instrument design, a new linear area CCD sensor has been developed under CNES responsibility. This detector has four lines 6000 13-μm square pixels long with four stripe filters, one in front of each of them. The detector itself
