Abstract

A passive optical-Hartley transform of white light scenes was performed by means of a rotational shear interferometer. The full visible band was utilised by employing a colour corrector which compensated for wave-length dependence of the fringes. This transform can be used for filtering, moment calculation, or for direct detection. An inverse transform was also realised, which allowed retrieval of the original object, although at a low efficiency.
