From: Quantitative phase imaging based on holography: trends and new perspectives
The k-space modulations offer side-band measurement using the analyticity of sideband wave. In non-interferometric configuration, the spatial field distribution in the complex-domain is reconstructed from single detection in the real-domain. It belongs to the Fourier-domain non-interferometric method in Fig. 3f. In the interferometric configuration, it can improve the imaging throughput using analyticity of half bandwidth in the interferogram. a Schematic illustration of configuration, sample wave in complex-domain, and its k-space in the interferometric-based KK holography (KKH). b Schematic illustration of configuration, sample wave in complex-domain and its k-space in the interferometric-based KK holographic multiplexing (KK-HM). c Schematic illustration of configuration, sample wave in complex-domain and its k-space in the non-iterative intensity-based KK (NIKK) reconstruction. d Schematic illustration of configuration, sample wave in complex-domain and its k-space in the intensity-based KK (IBKK) holography. e−h The detections and its k-space in real-domain from (a−d). i−l The reconstructions from (e−h)
