  In a computer-generated holographic projection system, the image is
reconstructed via the diffraction of light from a spatial light modulator. In
this process, several factors could contribute to non-linearities between the
reconstruction and the target image. This paper evaluates the non-linearity of
the overall holographic projection system experimentally, using binary phase
holograms computed using the one-step phase retrieval (OSPR) algorithm, and
then applies a digital pre-distortion (DPD) method to correct for the
non-linearity. Both a notable increase in reconstruction quality and a
significant reduction in mean squared error were observed, proving the
effectiveness of the proposed DPD-OSPR algorithm.
