Holographic Imaging Could Be Used to Detect Signs of Life in Space


Jay Nadeau, Research Professor of Medical Engineering and Aerospace, and colleagues are exploring ways to sample and identify living microbes in the outer solar system. Her proposal is to use new microscopes on spacecraft that could visit the icy moons of Enceladus (Saturn) and Europa (Jupiter) and to collect and search water samples for life. [Caltech story]

Digital Holographic Microscopy


Professor Morteza Gharib, and Dr. Jay Nadeau from GALCIT, as well as Dr. Christian Lindensmith from JPL are three of the four principle investigators on the holographic microscope project, dubbed SHAMU (Submersible Holographic Astrobiology Microscope with Ultraresolution). Their ultimate goal is to send the microscope on a spacecraft to search for biosignatures—signs of life—on other worlds such as Mars or Saturn's icy moon Enceladus. Holography is a method for recording holistic information about the light bouncing off a sample so that a 3-D image can be reconstructed at some later time. Compared to microscopy, holography offers the advantages of focusing over a relatively large volume and of capturing high-resolution images, without the trouble of moving parts that could break in extreme environments or during a launch or landing.
