Coded aperture incoherent digital holography Conference Paper uri icon


  • Imaging systems can be broadly classified into laser-based coherent systems and incoherent systems. Incoherent imaging systems may offer certain advantages over coherent imaging systems, including low cost light sources and speckle-free imaging [1,2]. This applies to digital holography systems as well. Even though the field of holography gained rapid development due to the invention of the laser, digital holography systems using incoherent light sources have recently attracted attention due to various advantages they possess. One such system is the self- informative-reference holography system dubbed Fresnel incoherent correlation holography (FINCH), which was invented in 2007 [3,4]. In FINCH, the width of the optical transfer function (OTF) is twice of that of a conventional coherent imaging system of similar numerical aperture (NA), and has a uniform response to all the frequencies of the OTF [5,6]. As a …
