A method of recording content comprising the steps of : providing a content storage medium comprising a pre-recorded grating or hologram
A multipoint laser Doppler vibrometer system (1) comprises a laser diode (2), beam expanding lens (3), a holographic optical element (HOE, 4) and a CMOS camera (5) receiving reflected light via optics (6). The HOE (4) is a hologram of a flat diffusely reflecting surface. Some light (8) is diffracted by the recorded hologram in the HOE (4) to provide a reference beam of light that is directed back towards the camera (5). Apart from some absorption the remaining light (9) continues onwards to illuminate the object The light that is reflected and scattered from the object (10) passes efficiently through the HOE (4) and interferes with the reference light (8) that is holographically reconstructed by the HOE (4) and subsequently detected by the camera (5). The beam from the laser diode (2) is divergent, which means that the sensitivity vector varies across the field of view.
The present application provides a method of manufacturing a reflection hologram. The method comprises the steps of placing a first pattern of activating material upon a layer of inactive holographic recording material to selectively activate the layer and exposing the layer to holographic recording process for producing a reflection hologram.
A sensor device comprising a holographic element comprises a grating or hologram recorded in a holographic recording medium wherein at least one physical and/or chemical and/or optical characteristic of the holographic element or the image produced by it varies as a result of variation in relative humidity or moisture content in the air surrounding the element. Also provided is an acrylamide-based photopolymer and an acrylamide-based reflection hologram.
