Diffuse optical tomography (DOT) is an emerging technique for functional biological imaging. The imaging quality of DOT depends on the imaging reconstruction algorithm. The SIRT has been widely used for DOT image reconstruction but there is no criterion to truncate based on any kind of residual parameter. The iteration loops will always be decided by experimental rule. This work presents the CR calculation...
In this paper, we report on a micro tunable cat's eye retro-reflector. The tunability is obtained through the use of a smart film, a polymer dispersed liquid crystal device (PDLC). The cat's eye device consists of three subassemblies, a front-side focusing unit, the smart film, and a back-side reflecting unit. The characterization of the device, considering possible fabrication inaccuracy such as...
