The Direct On-Chip Digital Optical Synthesizer (DODOS) program seeks to create a technological revolution in optical frequency control analogous to the disruptive advances in microwave frequency control in the 1940s.
The Gamma Ray Inspection Technology (GRIT) program seeks transformational approaches to achieving high-intensity, tunable, and narrow-bandwidth gamma ray production, but in a compact form factor suitable for transporting the source to where the capability is needed.
Coherent, short-wavelength UV light is useful for a range of applications such as decontamination, precision manufacturing, real-time medical diagnostics, and chemical and biological identification using Raman spectroscopy. However, many applications are unable to transfer out of the lab because the UV lasers needed to generate these coherent photons are prohibitively large, complicated and expensive.
The RadioBio program aims to establish whether functional signaling via electromagnetic waves between biological cells exists and, if it does, to determine what mechanisms are involved and what information is being transferred. The program seeks to determine the validity of electromagnetic biosignaling claims and, where evidence exists, understand how the structure and function of these natural “antennas” are capable of generating and receiving information in a noisy, cluttered electromagnetic environment.
The Rapid Threat Assessment (RTA) program aims to provide critical information to speed production of medical countermeasures to protect U.S. forces against novel chemical and biological weapons. Such weapons have historically been mass-produced within a year of discovery. Development of countermeasures, however, currently takes far longer. Using current methods and technologies, researchers require decades of study to gain a cellular-level understanding of how new threat agents exert their effects.
