A number of low gravity materials processing experiments such as crystal growth studies require a specialized optical system capable of flow visualization. several such systems have been built for use in space and ballistic aircraft flights, including schlieren systems. however, no color schlieren… More

This investigation will be directed towards an instrument development for both terrestrial and microgravity environments involving liquid drop protein crystal growth. visualization and recording of parameters characteristic of growth in high quality protein crystals is important to the optimization… More

This investigation will be directed towards the development of a high-accuracy cryogenic linear actuator. one of the most straightforward approaches to the problem of linear motion at cryogenic temperatures uses a rotating stepper motor and leadscrew arrangement to achieve the desired resolution and… More

We propose development of a miniaturized displacement sensor suitable in size and cost for mass-quantity use in adaptive and active optics applications. These sensors will be designed for the very high resolution required for precise control of local mirror shapes, segment location, and edge… More
