Ultraviolet Solar Blind Imaging

Silicon based charged couple devices (CCD) have been the workhorse of solid state imaging technology for use in the visible spectrum (400-700nm). Unfortunately silicon systems have limited response in the ultraviolet (190-400nm). We propose an entirelynew approach to imaging in the ultraviolet range, utilizing high surface area materials, that represents a paradigm shift in imaging technology. We expect quantum efficiencies of greater than 10% from 190-400nm. Inherent in our approach is the ability toproduce imaging systems that are not constrained by the size of a single crystal silicon wafer but instead are scaleable to dimensions that can be measured in square feet. In addition our device architecture will allow for the exposure of each individualpixel to be user defined. This will allow discriminating targets that have high contrast such as glare or rocket plumes.We propose an entirely new approach to detection in the ultraviolet solar blind spectral range. This program will produce a productcapable of detecting UVA and UVB radiation. The consumer product produced will be lightweight, portable and low cost such that an individual can monitor exposure to cancer causing UV radiation. Townsend Science and Engineering (TS&E) will possess the twocritical elements for successful commercialization. The first is our unique technical solution to UV detection. The second is TS&E has already established direct market channels to consumers. The principal investigator for this program is a board member ofa new ecommerce company that has already raised several million dollars of private capital and will enable TS&E to sell its products directly to millions of on-line consumers. Another key strategic partner brings its 100 retail outlets that will serve asanother enviable point of entry for the consumer products produced by this program.
