We demonstrate high performance photo detecting MOSFETs based on ultrathin (< 20 nm) single crystal germanium nanomembrane. This photo detecting MOSFET shows tunable wavelength-selective properties and high photocurrent gain. © 2016 OSA.

Baseline calibration is needed in most of SAR interferometry processing. An iterative optimization of baseline with constrain of relative platform position is presented in this paper. The SAR passes which gives inaccurate platform position is successfully detected and calibrated using this algorithm. After processing, new estimated baseline improves the quality of interferogram. Existence of reference Digital Elevation Model (DEM) error and atmospheric phase screen (APS) can also be detected from the convergence value. This method is based on a reversed concept of platform position estimation from interferometric result. Validation of method performed on multiple SAR images over Singapore. © 2010 IEEE.
