In conventional light field near eye display (LF-NED) using pinhole aperture arrays, as the pupil size changes under different conditions, the overlapping area of adjacent elemental images is not certain. This is the primary cause of an uncertain net-shaped bright-dark pattern on the image plane. In this paper, a proof-of-concept light field near eye display prototype for virtual reality applications...
This paper presents a W-band 2 2 focal-plane array (FPA) for passive millimeter-wave imaging in a standard 0.18 SiGe BiCMOS process (). The FPA incorporates four Dicke-type receivers representing four imaging pixels. Each receiver employs the direct-conversion architecture consisting of an on-chip slot folded dipole antenna, an...
A fully-integrated silicon-based 94-GHz direct-detection imaging receiver with on-chip Dicke switch and baseband circuitry is demonstrated. Fabricated in a 0.18-μm SiGe BiCMOS technology (fT/fMAX = 200 GHz), the receiver chip achieves a peak imager responsivity of 43 MV/W with a 3-dB bandwidth of 26 GHz. A balanced LNA topology with an embedded Dicke switch provides 30-dB gain and enables a temperature...
