a The experimental setup of WISH. The green arrow indicates how the field propagates inside the sensor. b The high-resolution estimate of field u is recovered by iteratively enforcing the intensity measurement constraints on the sensor plane and averaging estimates from multiple patterns on the SLM plane. c To recover the incident wavefront from a dusted fingerprint, we projected eight random phase patterns on the SLM and captured the corresponding images. After the WISH algorithm has been performed, the high-resolution amplitude and phase reconstructions are recovered
