Theoretical and Applied Optics

Non-diffracting arrays

Realization of a phase mask. Test in white light.
z = 0

Realization of a phase mask. Test in white light.
z = 100 mm

Objective

To develop a spatial resolution characterization bench adapted to new infrared detectors with a very large number of small pixels, considering the fact that conventional methods are no longer suited to these new generation components.

DOTA’s contribution

Development of a white light test pattern projection technique using neither optics nor focusing device, based on the use of the Talbot effect.
