About

Rosen's work focuses on Digital and Computational Optics, Holography, and Optical Imaging. He became known for his contributions to the technology of incoherent digital holography. In 2007, he co-invented the Fresnel Incoherent Correlation Holography (FINCH), a new method of recording digital holograms of targets illuminated by white light. In 2017, he co-invented the interferenceless Coded Aperture Correlation Holography (I-COACH), a new way of recording digital holograms without wave interference. FINCH and I-COACH are used for three-dimensional imaging of general three-dimensional objects observed from a single viewpoint using a single camera shot. In 2018, Rosen co-invented an image reconstruction method called non-linear reconstruction, which has now become one of the widely used methods in coded aperture imaging and incoherent holography. In 2019, Rosen and his PhD candidate Angika Bulbul introduced a method of using the partial aperture area of a lens to obtain a similar image resolution to the full aperture area. This can save cost, time, and material needed for space telescopes. In 2022, the non-linear reconstruction method co-invented by Rosen was combined with the well-known deconvolution method Lucy-Richardson algorithm, to create the Lucy-Richardson-Rosen algorithm. The Lucy-Richardson-Rosen algorithm exhibited a significantly improved performance in convergence and estimation of the solution compared to the Lucy-Richardson algorithm. The Lucy-Richardson-Rosen algorithm was initially demonstrated to deconvolve blurred mid-infrared images obtained from the micro-spectroscopy system of the Australian synchrotron. Later, it exhibited good deconvolution for spatially symmetric point spread functions. Prof. Rosen has authored over 340 scientific publications, including three books and 16 patents
