We derived the point-spread function (PSF) including the recording and reco
nstruction systems of the modified triangular interferometer; the modified
triangular interferometer forms incoherent holograms without bias and the c
onjugate image. We also derived and analyzed the resolution of the modified
triangular interferometer and compared it with that of the conventional on
e for amplification factor, wavelength, and hologram size. (C) 2001 Optical
