Title: David F Prelewitz: Pioneer in Digital Imaging and Reduction of Speckle

Introduction:

David F Prelewitz is an esteemed inventor based in Rochester, NY (US), who has made significant contributions to the field of digital imaging. With a strong background in coherent radiation imaging systems, Prelewitz has successfully developed methods to reduce the presence of speckle, resulting in clearer and more accurate digital images. This article delves into his impressive achievements and highlights his noteworthy contributions.

Patents and Innovations:

David F Prelewitz has been granted a total of five patents, primarily focused on the development of digital imaging assembly and the reduction of speckle. One of his notable patents is a coherent radiation imaging system that generates digital images with a reduced amount of speckle. This system utilizes radiation from a long-coherence length source to capture images of a sample.

In this patented method, the output coherent wave is divided into several wavelets, and the spatial phase of each wavelet is modulated to a known and different extent. The modulated wavelets then illuminate the sample and interact with it, resulting in perturbed wavelets. By creating a spatial phase map of each perturbed wavelet and converting it into a sample image using an image reconstruction program, Prelewitz successfully obtains a plurality of sample images. These sample images are statistically averaged to form a final image with significantly reduced high-frequency speckle, leaving behind only the optically resolvable lower frequency phase information.

Companies and Collaborators:

David F Prelewitz has contributed his expertise to several prominent companies within the innovation and technology sector. He has worked with Technology Innovations, LLC, and Wavefront Analysis, Inc., demonstrating his ability to apply his innovative solutions for the benefit of these organizations.

Prelewitz has collaborated closely with accomplished individuals, including Robert W Gray and Rolf Gerchberg. Together, they have pushed the boundaries in the field of digital imaging and contributed to the development of novel technologies to reduce speckle in coherent radiation imaging systems.
