Performances for nowadays optronic systems require focal plane arrays (FPA) with an increasing number of detectors.The "pushbroom" technic is well adapted to earth observation in the visible range with the availability of long linear CCD'S offering thousands of pixels.In the infrared, line scan systems are preferred at the present time because technological difficufties have to be overcome in order to get long linear arrays. Among the most important, are: -Difficufties to have a large cold focal plane with a temperature uniformfty of a few degrees.Difficufties to get good detection material over large surface. Mechanical or optical butting technology can be used there but with dead pixels and/or side effects.Very low cold shield efficiency due to the geometry of the long linear array.Very high development costs.MATRA DEFENSE UAO (*) has made the design of a new infrared FPA concept which has the advantage to overcome all drawbacks listed previously (patented design).The idea consists to transform the pixel arrangement geometry of a 2D array which is available off the shelf into a long linear FPA using a coherent infrared fiber optic reformatter.In order to demonstrate the feasibility of this new FPA concept, a camera breadboard has been buift. This task has been supported by the French MOD ( SiTE). This paper describes this breadboard and gives main technical performances.

This paper deals with a breadboard of CO2 laser Doppler rangefinder based upon the "chirp pulse compression" technique, and realized in common by Thomson -CSF and Cilas. It recalls some design considerations derived from properties of heterodyne detection and basic radar theory, then describes the principle and main components of this equipment, and evaluates its overall performance.
