Abstract
With the increasing deployments of smaller instruments for scientific observations from space there is a need for innovative sensors and techniques. These solutions have to be compact, low power, and operate with improved efficiencies. Commercial vendors have been able to produce hyperspectral instruments with various improved capabilities such as incorporating innovative spectrometers, or a single chip with spectral imaging capabilities.

Abstract
We discuss SPIDER-PIIT that consists of densely packed 2D/3D photonic integrated circuits (PICs) containing interferometers and spectrometers to measure the amplitude and phase of the visibility function at spatial frequencies that span the full synthetic aperture. Actual image retrievals from SPIDER-PIITs will be demonstrated.

Abstract
Abstract
Random projections of RF signals are obtained by modulating the signal onto an optical carrier and propagating through a multimode waveguide. These random projections are digitally post-processed to obtain the properties of unknown input signals within compressive sensing and reservoir computing systems.
