We present a new technique combining digital holography and tomography to make path-resolved measurements of a turbulent air volume. An array of optical beams at different propagation angles is transmitted through the volume under test, interfered wi

In remote-sensing applications, digital holography data often includes both phase errors from atmospheric turbulence and fully developed laser speckle from rough objects. When processing single-shot data, i.e., data from a single hologram, the high s

We present a new approach to coherent averaging in digital holography using singular value decomposition (SVD). Digital holography enables the extraction of phase information from intensity measurements. For this reason, SVD can be used to statistica

This paper reports design, fabrication, and experimental demonstration of a silicon nitride photonic integrated circuit (PIC). The PIC is capable of conducting one-dimensional interferometric imaging with twelve baselines near λ = 1100-1600 nm. The

The Lockheed Martin Advanced Technology Center and the University of California at Davis (UC Davis) has developed an interferometric imaging system based on photonic integrated circuits (PICs). This approach could enable a new hardware architecture w

We report on digital holographic imaging through atmospheric turbulence. Data recorded with aberrations is corrected during post processing using an iterative sharpness-metric maximization algorithm. Assuming the correction cancels the actual wavefro

We present a space telescope concept based on a spherical primary mirror that is composed of segments mounted on small satellites that dock together. The telescope design and an on-orbit alignment approach will be discussed.
