Abstract
We proposed a new incoherent optical frequency selection method called two-pack frequency-selective (TPFS) incoherent holography, which compresses two on-axis holograms into a single multiplexed on-axis hologram without loss of magnification and resolution. The spectrum we want to reconstruct is intercepted by multiple confounding correlation terms in the spatial frequency domain. The background bias term and conjugate term can be effectively suppressed. This work is the first to attempt a multiplexed reconstruction in the field of incoherent light. Experiment results highlight the potential of the proposed method in several areas, such as compressed holography and extended field of view imaging.
