MTF-Derived Image Metric for the Performance of Laser-Based Imaging Systems
نویسنده
چکیده
The long-term goal of this project is to derive a general and comprehensive algorithm to calculate a scalar image metric which will help quantify the performance of emerging laser-based imaging systems in the highly variable optical littoral environment. After validation, this image metric will then be used to assist in mission planning by providing up-to-date maps of the expected system performance for each of these imaging platforms along littoral routes and areas of interest to the Navy.

Study of Laminated Composite MEMS and NEMS Performance in Nano Metric Operations
Precision of nano-metric operations is an important issue in nano-engineering studies. Several operative parameters might affect the quality of results. The parameters of the nano world are significant but not entirely controllable. However, the geometrical and mechanical properties of micro cantilevers are completely controllable. So, controlling the sensitivity of resulting image through t la...
