Ghost imaging is used in encryption, remote sensing, and biomedical imaging applications. This work relates to the generic problem of remote active imaging; that is, a source illuminates a target of interest and a receiver collects the scattered light off the target to obtain an image. Conventional imaging systems consist of an imaging lens and a high-resolution detector array [e.g., a CCD (charge coupled device) array] to register the image. However, conventional imaging systems for remote sensing require high-quality optics and need to support large detector arrays and associated electronics. This results in suboptimal size, weight, and power consumption.

This receiver also can be used in harsh environments encountered in aerospace and mining.

Wireless sensors connected in a local network offer revolutionary exploration capabilities, but the current solutions do not work in extreme environments of low temperatures (200K) and low to moderate radiation levels (

This technique can be applied to a variety of applications, including leak detection, personal health monitoring, and environmental monitoring.

A new microsensor fabrication approach has been demonstrated based upon the use of nanostructures as templates. The fundamental idea is that existing nanostructures, such as carbon nanotubes or biological structures, have a material structure that can be used advantageously in order to provide new sensor systems but lack the advantages of some materials to, for example, operate at high temperatures.

As NASA’s Director of Space Technology Programs, Michael Gazarik contributes to the development of technology that can be applied to NASA’s exploration systems, space operations, and science missions. Gazarik integrates and tracks all investments across the agency. Prior to this appointment, he served as the Chief Technologist at NASA headquarters. NIAC
NASA Tech Briefs: The NASA Innovative Advanced Concepts, or NIAC, program is seeking proposals for revolutionary ideas that have the potential to transform future aerospace missions. What kinds of ideas are we talking about? Michael Gazarik: NIAC is one of our most exciting programs. We have ten programs that cover a broad range of technology development. This is a program that actually ran for a number of years and then went dormant. Last year, we resurrected it, got it up and running again, and we’re looking at advanced concepts that will someday enable us to do great things in exploration and exploring the universe. They range from new and advanced power systems, to new types of propulsion, to ways to protect our astronauts from radiation.
