Spectrum and space resolved 4D imaging by coded aperture correlation holography (COACH) Conference Paper uri icon


  • Abstract: An advanced optical configuration of coded aperture correlation holography (COACH) has been developed using a diffractive objective lens to enable resolving illumination colors and the 3D spatial information of objects. OCIS codes: (090.1995) Digital holography; (110.0110) Imaging Systems; (090.1760) Computer holography; (050.5080) Phase shift; (050.0050) Diffraction and gratings; … Coded aperture correlation holography (COACH) is a recently developed incoherent digital holographic technique for recording and reconstructing objects with high axial resolution [1]. COACH uses an optical configuration similar to that of a well-known incoherent digital holographic technique called Fresnel incoherent correlation holography (FINCH) [2, 3]. The difference is that the quadratic phase mask displayed on the spatial light modulator (SLM) in the case of FINCH is replaced by a random-like coded phase mask (CPM). In …
