Exiting wavefront

WebAbstract: A cascade of microlens arrays that are decentered with respect to each other is one potential method for beam steering; the magnitude of the steering angle depends on the amount of decenter. A simple argument is presented that shows that the output of such a system is analogous to the output of an optical phased array. The periodic nature of the … Webrecords the intensities of the propagated wavefront. As the probe beam is narrow, it interacts with only a small part of the object each time, and the probe is then scanned across the entire object in steps. Each time, the detector only records the square of the magnitude of the Fourier transform of the wave-front exiting from the object ...
