摘 要:To achieve the goal of the proposal, we created nano-structured surfaces to increase the pixel density and hence resolution of the opto- electronic sensor array by a factor of 3 in each direction, x and y. The proof of concept of this mathematical framework in the visible part of the optical spectrum was published in 2 journal articles (both published in Applied Physics Letters). In addition to this, we also experimentally applied the same concept to IR part of the optical spectrum and thus demonstrated the feasibility of our approach for IR focal plane arrays. these results will be presented at SPIE Defense, Security and Sensing Conference in April 2012.
