Integrated optical means for micro holograms recording

The proposed paper relates to holographic optical elements that are used for recording micro holograms with usage of laser source of coherent radiation. Such devices for micro holograms recording are used for recording of information presented in digital view into light sensitive materials for future storage and reconstruction of recorded information. Important characteristic of recording devices is the overall active volume of device optical part. The challenging task is to provide considerably less volume of recording device optical part at the cost of using integrated optical elements. Almost all existing solutions have a big quantity of different optical elements divided by air spacers. The relative positions of all these elements affects on working efficiency of whole device. We propose a scheme providing fundamental improvements of the basic scheme in parts of overall device sizes, quantity of elements, and combined functionality of each element. The main advantages of proposed solution are as follows: First, this solution utilizes various integral optical elements, where each element is a united not adjustable optical element, replacing separate and adjustable optical elements with various forms and configurations. Second, geometrical form of integral elements provides small sizes of whole device. Third, geometrical form of integral elements allows creating a flat device. And finally, absence of adjustable elements provides rigidity of the whole devices. The usage of integrated optical means based on waveguide holographic elements allows creating a new type of compact and high functional display devices for various applications like mobile and consumer usage.
