Abstract
We show using two-dimensional simulations that the dual-space microscopy (DSM) phase-recovery algorithm converges to the correct result for arbitrary samples. We present experimental results obtained by implementing the DSM technique using a laser. We demonstrate that DSM produces synthetic images with a large field of view when a laser is used as the illumination source. However, speckles affect the quality of the obtained images.
•DSM converges to the correct result for arbitrary samples.•FPM and DSM are implemented using Hemi-spherical Laser Guider.•DSM relates the diffraction spot size in Fourier domain to the FOV in Real plane.
