Abstract
We have developed a new on-axis digital holographic technique, heterodyne
holography. The resolution of this technique is limited mainly by the amount
of data recorded on two-dimensional photodetectors, i.e., the number of pixels
and their size. We demonstrate that it is possible to increase the resolution
linearly with the amount of recorded data by aperture synthesis as done in
the radar technique but with an optical holographic field.
