A class of Fourier-related functions such as the fractional Fourier tr
ansform, the Hartley and the fractional Hartley transform, the Mellin
and the fractional Mellin transform, are implemented in the time-domai
n. To accomplish this task temporal analogue of beam splitters, cube c
orner prisms and holograms are found. (C) 1998 Elsevier Science B.V.
