An annealing algorithm to correct positioning errors in ptychography
My method (ptychography) that has already revolutionised synchrotron-based X-ray microscopy (by disposing of poor-quality Fresnel zone plate lenses) has previously been limited by the mechanical and electronic stability at the amplitude of 0.05nm beam position control. Developed as part of EPSRC Basic Tech Grant EP/E034055/1, the work overcomes this key blockage. A patent on the technique was sold to Phase Focus Ltd (www.phasefocus.com), which is incorporating it in an electron microscopy add-product in conjunction with Gatan Inc. (www.gatan.com) that enhances image resolution by several factors and produces very sensitive phase images for imaging (amongst many things) nano-scale magnetic fields.
