Space Solar Power Initiative
Caltech and Northrop Grumman Corporation have signed a $17.5 million sponsored research agreement for the development of the Space Solar Power Initiative (SSPI). The initiative will develop technologies in three areas: high-efficiency ultralight photovoltaics; ultralight deployable space structures; and phased array and power transmission. "The Space Solar Power Initiative brings together electrical engineers, applied physicists, and aerospace engineers in the type of profound interdisciplinary collaboration that is seamlessly enhanced at a small place like Caltech... We are working on extremely difficult problems that could eventually provide the world with new, and very cost-competitive technology for sustainable energy,” said EAS Chair Ares Rosakis.

Ali Hajimiri's New Camera Chip Provides Superfine 3-D Resolution
To make an exact copy of an object with a 3-D printer, you must first produce a high-resolution scan of the object with a 3-D camera that measures its height, width, and depth. The most sensitive systems generally are too large and expensive to be used in consumer applications. Ali Hajimiri, Thomas G. Myers Professor of Electrical Engineering, has created a new device called a nanophotonic coherent imager (NCI) that is an inexpensive silicon chip less than a millimeter. The NCI provides the highest depth-measurement accuracy of any such nanophotonic 3-D imaging device. 3-D imaging may be a possible feature in future smartphones. [Caltech story]
Engineering and Art
Students in Professor Hillary Mushkin’s media arts seminar (E/H/Art 89 New Media Arts in the 20th and 21st Centuries) have once again put on a unique exhibition highlighting art and engineering. The course provides a platform for an expanded understanding of engineering and an active, project-based engagement with art history.
