Abstract

Dual-wavelength digital holography has advantages over single-wavelength digital holography in resolving phase discontinuities at high aspect-ratio. However, the operations are very time-consuming and cannot achieve real-time processing. We realized the phase reconstruction of dual-wavelength off-axis holograms on Java platform, and used GPU to accelerate the computation-intensive part. Preliminary experiments show we can reconstruct 1 mega pixel holograms continuously at a speed of 41 fps, which can satisfy the stable video-rate. Through Java, the system can be easily combined with numerous plugins of ImageJ, such as filters, LUT for pseudo-color, 3D tools, etc. This is of great help to the subsequent image analysis and processing.
