Enabling Design Concepts for a Flight-Qualifiable Optical Delay Line
In an interferometer, an Optical Delay Line(ODL) must be able to inject a commanded pathlength change in incoming starlight as it proceeds from a collecting aperture to the beam combiner.

Low Mass Muscle Actuators (LoMMAs) Using Electroactive Polymers
NASA is using actuation devices for many space applications and there is an increasing need to cut their cost as well as reduce their size, mass, and power consumption. Existing transducing actuators, such as piezoceramics, are inducing limited displacement levels. Potentially, electroactive polymers (so called EAP) can be formed as inexpensive, low-mass, low-power, miniature muscle actuators that are superior to the widely used actuators.
