Fourier incoherent single channel holography (FISCH) is a method for recording spatially
incoherent digital Fourier holograms. We present a general design of enhanced FISCH with a
smaller optical path difference between interfering beams, when compared to our initial design
[Opt. Lett. 37, 3723 (2012)]. This reduction enables a proper system operation
with a wider bandwidth. Potential resolution enhancement of the images reconstructed from the
FISCH holograms consequentially follows.
