We present a variation of the dual-space and Fourier ptychographic algorithms adapted for imaging samples simultaneously illuminated by multiple beams coherent with each other. The modified algorithms were successfully tested using the light diffracted by a Ronchi-ruling as the source of illumination. High-resolution images with a resolution better than the Rayleigh resolution limit were demonstrated.
- Coherent illumination direction Multiplexing (IDM)
- Moiré patterns
