Goosing germs in space and robotic, holographic microscopy
Space.com: How Holograms Could Aid Alien Life Hunt
DHM has several advantages over ordinary imaging microscopy when it comes to possible use on a space mission, Lindensmith said. For example, it’s easy to make DHM instruments autonomous; there is no need for knob-twiddling to bring a target object into sharp view.
“The thing that makes it magic is, we don’t have to do any focusing,” Lindensmith told Space.com at AGU. “We can reconstruct any image in the object field.”
