We discuss the trade-off caused by the system parameters, and the performance degradation caused by the angular momentum of the rotational motor for shifting multiplexing. We also propose applying phase-integrated double-frequency grating shearing interferometer (PI-DFGSI) to makes the reading with moving disc being possible, and thus improves the system performance.

 

Radial and azimuthal polarization converters are capable to convert a light into radially and azimuthally polarized lights which have several applications. A new design of holographic converters is proposed and fabricated. This design has the advantages of high diffraction efficiency, suitable for low-cost mass production and has high application potential.

 

This paper proposes an innovative method for stereoscopic depth measurement by designing a computer generated hologram (CGH), which can diffract structured light patterns, and calculating the centroid distances of projected speckles on measured surface. The device was fabricated and system was performed to verify the feasibility of the method.

 

We present a study of theoretical finding of additional phase error of a volume
holographic storage disc during the reading process when the disc is rotated or displaced. It will
decrease the bit error rate of a phase-only signal. Then we propose a novel approach to solve
the problem.

 

A one-shot method to describe the profile of a rotating object is presented. A sinusoidal fringe pattern is illuminated on the rotating object. Fringes on the rotating object observed by the digital camera are blurred by the motion. The blurred fringes provide analyzable information to describe the surface profile.
