Abstract:
This study presents a new technique to measure the phase
difference between two diffracted fields: The field diffracted by a reference
object and the field diffracted by an unknown object. For that we use
the interferential technique of Young slits. We measured the phase difference
between the diffracted fields of two rods of resin. And knowing the phase
of the diffracted field of the reference object helps deducing the phase
of the field diffracted by the sample. This setup is simple and it is
very strong in the presence of disturbances because both objects are illuminated
with the same incident beam. Moreover, this technique allows us measuring
the phase of the diffracted field on a wide range of angle so that a high
resolution of the image can be obtained.
