Noise reduction for digital holograms in a discrete cosine transform (DCT) domain
digital hologram noise reduction discrete cosine transform holographic reconstruction

This paper presents a method for reducing noise in a digital hologram, which occurs during
acquisition. The algorithm proposed initially transforms a digital hologram into frequency-domain
data thro...
On-demand Optical Tweezers Using Computer-generated Phase Holograms
Holographic optical tweezers Spatial light modulator Time-multiplexing
2009/6/2
We have developed an optical tweezers system by on-demand operation. In this work, we achieved real-time displacement of a trapped particle together with a fixed trapped array of particles. The displa...
