Abstract
A self-interference digital holographic system obtains interference patterns of incident light using a simple geometric phase lens, and obtains a holographic image of a target object using the interference patterns. The self-interference digital holographic is fabricated simply in a low cost and in a miniaturized size, and the use thereof as actual products is extended to a wide range of applications. The phase of incident light is be changed by rotating a polarizer, independently of a change in the optical path. Phase-shifting effects are obtained with fewer errors in all wavelength ranges, and a more accurate holographic image is produced. A single birefringence hologram is obtained by a one-time image-capturing process by simultaneously forming interference patterns from phase-shifted linearly-polarized beams by space division, using a phase shifter on the basis of space division. Moving holographic images can be captured.
