Paper Abstract

The multi-focal imaging system is implemented with a spatial light modulator (SLM) placed at the Fourier plane of the system. The multiplexed grating pattern displayed on the SLM can modify the wavefront of the incoming light and compensate aberrations existing in the system. We demonstrate the multiplexed grating pattern displayed on the SLM can acquire 25 images in a short time sequence by acquiring 9 images at different depths simultaneously in each exposure. We compare and discuss the advantages and disadvantages between the digital micro-mirror device (DMD) with the liquid crystal spatial light modulator (LC-SLM) based on the theory and experimental results.
