Holographic optical element manufacturing method for enhancing image brightness
A recently filed patent (Publication Number: US20230314686A1) describes a method for producing a holographic optical element. The method involves several steps, including laminating a master on a substrate, recording the interference pattern of the master on a photosensitive material, and producing multiple optical elements by repeating the recording process at different angles of incidence. These optical elements are then combined to form the holographic optical element.
In one embodiment of the method, the photosensitive material is irradiated with the incident beam after rotating the substrate by a predetermined angle. This rotation helps ensure that the incident beam is within a specific range of angles for optimal diffraction by the master.
The resulting holographic optical element consists of multiple optical elements combined together, each with interference patterns recorded at different inclination angles. These inclination angles can gradually increase or decrease in a predetermined direction, providing a desired effect.
The patent also describes an apparatus for implementing this method. The apparatus includes a lamination unit for forming a laminate with a substrate, master, and photosensitive material, a beam irradiation unit for recording the interference pattern on the photosensitive material, a rotation control unit for controlling the angle of incidence of the incident beam, a master removal unit for separating the photosensitive material from the master, and a combining unit for combining multiple optical elements to form the holographic optical element.
Overall, this patent presents a method and apparatus for producing holographic optical elements with controlled interference patterns. The method allows for the creation of optical elements with different inclination angles, which can be combined to achieve specific visual effects. This technology has potential applications in various fields, including display technologies, optical devices, and augmented reality.
