Dynamic time multiplexing fabrication of holographic polymer dispersed liquid crystals for increased wavelength sensitivity
Described herein is a new holographic polymer dispersed liquid crystal (HPDLC) medium with broadband reflective properties, and a new technique for fabrication of broadband HPDLC mediums. The new technique involves dynamic variation of the holography setup during HPDLC formation, enabling the broadening of the HPDLC medium's wavelength response. Dynamic variation of the holography setup may include the rotation and/or translation of one or more motorized stages, allowing for time and spatial, or angular, multiplexing through variation of the incident angles of one or more laser beams on a pre-polymer mixture during manufacture. An HPDLC medium manufactured using these techniques exhibits improved optical response by reflecting a broadband spectrum of wavelengths. A new broadband holographic polymer dispersed liquid crystal thin film polymeric mirror stack with electrically-switchable beam steering capability is disclosed.

HOLOGRAPHIC DISPLAYS AND METHODS
An example holographic display may comprise an angularly dispersive micromirror array and an optical assembly configured to emit, towards the micromirror array, a first ray of light having a first wavelength and a second ray of light having a second wavelength, the second wavelength being different to the first wavelength. The first ray of light is incident upon the micromirror array at a first angle of incidence and the second ray of light is incident upon the micromirror array at a second angle of incidence, the second angle of incidence being different to the first angle of incidence by a predetermined amount to at least partially compensate for the dispersive effects of the micromirror array along an optical axis of the holographic display.
