Architecture and Field Operation of a Portable Digital Holographic Microscope for In Situ Measurements of Bacterial Motility Open
The development of a next-generation, portable, digital holographic microscope enables the real-time volumetric characterization of bacterial behavior in extreme environments. This microscope is designed to observe bacteria in their native…

Antireflection coatings on starshade optical edges for solar glint suppression Open
Starshades are designed to enable the direct observation of an exoplanet by blocking the light of the planet’s star from reaching the telescope. As discussed in our companion paper [S. Shaklan et al., “Solar glint from uncoated starshade o…

Solar glint from uncoated starshade optical edges Open
The perimeter of a sunflower-like starshade has hundreds of meters of sharp edges that are directly exposed to sunlight. The sunlight diffracts and reflects from the edge resulting in a dual-lobed glint pattern that can be brighter than an…
