Abstract: A holographic substrate-guided wave-based see-through display can has a microdisplay, capable of emitting light in the form of an image. The microdisplay directs its output to a holographic optical element, capable of accepting the light in the form of an image. The microdisplay directs its output to a holographic optical element, capable of accepting the image from the microdisplay, and capable of transmitting the light. The holographic optical element couples its output to an elongate substrate, capable of accepting the light from the holographic lens at a first location, and transmitting the light along a length of the substrate by total internal reflection to a second location, the elongate substrate being capable of transmitting the accepted light from the second location.

The holographic lens couples its output to an elongate transparent substrate, capable of accepting the light in the form of an image from the holographic lens at a first location, and transmitting the light in the form of an image along a length of the substrate by total internal reflection to a second location spaced from the first location, the elongate substrate being capable of transmitting the accepted light in the form of an image at the second location.

Abstract: The present invention relates to admixtures production and to a method of application of the admixtures in cement and concrete technology. The method allows production of high-strength and high durable cement based systems, as well as cement systems with specially designed properties of cheap high-volume mineral admixture cements.
