Inline holography of miniaturized objects with an intrinsic reference angle determined by the sagitta

The twin image problem, well known in Gabor holography, greatly obstructs the output of high-quality holograms. Previous solutions include numerical and instrumental means to eliminate or mitigate issue. proposed method demonstrates feasibility using sagitta angle a spherical reference beam as an intrinsic within in-line holography. Along with miniaturized version object, allow for wide range object sizes, from millimeters meters, small variation original optical system. inherent allows separation images reconstruction hologram, while maintaining system on axis. Under lens-less Fourier criteria, peripheral information visual field interferes wave generate interference pattern that results hologram separated images.
