When trying to miniaturize opticalinstruments to the utmost, the physical phenomena that come into play become complex, fascinating and particularly interesting. Welcome to the world of nanophotonics
This work has been done by teams from" the Calibration, Instrument Building and Optical Measuring" unit and" the OpticalInstrument Design" unit of the Department of Theoretical and Applied Optics at Onera, in collaboration with the Utinam Institute of the Observatory of Besançon and the DGA / Aeronautical Techniques
The two optical modules of the Sieleters instrument viewed from below the aircraft (installed on the hatch. Sieleters is a cryogenic instrument with two separate optical modules operating respectively in" the medium wave" (3 to 5 m) and" long wave" (8 to 12 m) infrared bands
Methods and instruments for the metrological characterisation of flows and plasmas, based on optical spectroscopy, specific sensors or sources such as tunable lasers, OPO, LIDAR, photoacoustics, etc. Plasma sources and electric thrusters
