Abstract
En 中文
The image space of the reconstructed image from the hologram displayed on a digital micromirror device (DMD) is defined by the diffraction pattern induced by the 2D pixel pattern of the DMD, which works as a 2D blazed grating. Within this space, a reconstructed image of 100 mm x 20 mm is spatially multiplexed by a 2 x 5 DMD array that is aligned on a board, without using any extra optics. Each DMD chip reconstructs an image piece of the size 20 mm (width) x 10 mm (height). The reconstructed image looks somewhat noisy but regenerates the original object image faithfully.
