Computer-Generated Hologram Based on Reference Light Multiplexing for Holographic Display
Applied Sciences, 2021 In this article, we propose a reference light wave multiplexing scheme to increase the information capacity of computer-generated holograms. The holograms were generated by different reference light waves and superimposed together as a multiplexed ...

Holographic colour prints for enhanced optical security by combined phase and amplitude control
Nature Communications, 2019 Here, the authors fabricate a device that integrates multiple computer-generated holograms into a single colour print. Under white light, a colour image is seen, whereas illumination with a red, green, or blue beam from a handheld laser pointer projects ...

Interferometric Metrology Using Reprogrammable Binary Holograms [PDF]
, 2013 Interferometric methods for surface metrology have been widely used for many years due to their speed, accuracy and versatility. It is frequently necessary however to produce a known comparison reference surface to minimise the optical path difference ...

Advanced Materials, EarlyView.We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...
