Optical transceiver arrays

Abstract

An optoelectronic apparatus includes a sensing device, including a planar substrate and an array of sensing cells disposed on the substrate and including respective optical transducers, which are configured to couple optical radiation between the sensing cells and a target external to the substrate, thereby defining respective optical apertures of the sensing cells, and which are located at respective nodes on respective rows and columns of a two-dimensional rectangular grid such that no more than half the nodes on the respective rows and columns are occupied by the optical transducers. A scanner is configured to scan the optical apertures across the target along at least the rows of the grid so that the optical apertures are projected successively onto respective sequences of multiple nodes in the rectangular grid on the target.
