Paper Abstract

The optical transfer function of interference coatings in quasi-monochromatic light appears suitable to directly perform 2-D low-pass, band-pass and high-pass spatial frequency filtering. Uniformity of the coating over an extended area allows for space-invariant operation. Both coherent and incoherent processing are possible. In multiple wavelength illumination the optical information is coded into colour channels, corresponding to spatial frequency bands. This allows for parallel imaging in multiple wavelength with different transfer functions, and can result in pseudocolouring effects if suitable coatings such as unblocked interference filters are employed.
