Abstract: A technique that can maximize signal to noise ratio in systems that use beam steering, by steering both the transmit and receive signals. A beam splitter is used, which is positioned to receive both the light beam transmitted by the light source and the return light beam, and a scanning beam steerer, which is positioned to receive both transmitted light from the beam splitter and returning light from the target. Using a split portion of the beam, a reference signal can be provided to probe the ambient condition of the sensor, to sense conditions such as darkness and fog.

Abstract: In accordance with an embodiment of the present disclosure, there is provided a compact method for beam steering using a layer of transparent, electro-optical material sandwiched between two layers of conductive transparent material, which provides a voltage-controlled light beam steering system without any moving parts.

Abstract: In accordance with an embodiment of the present disclosure, there is provided a technique of using probe fed apertures to realize a waveguide feeding network that can be divided both parallel to the surface, and on different levels, of a co-fired ceramic substrate, such as a low temperature co-fired ceramic (LTCC) substrate. A horizontal feed network is divided into several sections, which can be stacked vertically in various different locations and on different layers within the substrate, and are connected by probe-fed apertures. In this way, waveguide dividing can be performed in directions that are parallel to the surface of the substrate and on different levels of the substrate, thereby increasing the efficiency of the use of the substrate volume and permitting dividing and combining of inputs and outputs in a more flexible manner.
