Abstract: The present invention relates to an image detecting method of an image detector which processes a shape of an edge of an image input aperture of a 2D image detector which is used in a terahertz band whose frequency is lower than that of infrared light to have a predetermined shape so that a diffraction pattern due to the aperture is not shown in a captured image or a contrast is weakened, thereby obtaining a clear object image with a reduced distortion.

Abstract: Disclosed is a binary neural network hardware apparatus. The binary neural network hardware apparatus includes a sense amplifier configured to compare a bit line voltage of a bit line with a predetermined reference voltage; an input unit configured to input the bit line voltage to the sense amplifier; and a threshold voltage regulator configured to be connected to an artificial intelligence binary synapse through the bit line and change the bit line voltage in multiple levels.

Abstract: Disclosed is a Cassegrain-type antenna. The Cassegrain-type antenna may comprise a main-reflector; a sub-reflector; and a radiator radiating beams by using a plurality of emitters. Also, a reflective surface of the sub-reflector has a shape of a trace formed by rotating a first curve having a vertex and being convex toward the main-reflector around a rotation axis spaced apart from the vertex.
