Luke A Pfister is an accomplished inventor based in Urbana, IL (US). He has made significant contributions to the field of imaging technology, holding three patents that showcase his innovative approach to enhancing image resolution and reconstruction.

Latest Patents

One of his latest patents is titled "Systems and methods for improving resolution in lensless imaging." This invention utilizes an optical phase grating to produce an interference pattern rich in intensity and spatial-frequency information from an external scene. The grating is designed with an odd number of repeated sets of adjacent horizontal portions, which are separated by steps and fill an area radiating outward from a central region. Each horizontal portion has a width that differs from its adjacent portions, allowing for the extraction of images and other relevant information from the interference patterns produced.

Another notable patent is "Highly accelerated imaging and image reconstruction using adaptive sparsifying transforms." This system employs efficient computational methods for high-quality image reconstructions from a limited number of noisy or degraded sensor imaging measurements. The processing device executes instructions to adapt a transform model to a set of image patches, allowing for the reconstruction of images by minimizing an optimization objective that includes a transform-based regularizer and a data fidelity term.
