Joseph Rosen (professor)

In 2022, the non-linear reconstruction method co-invented by Rosen was combined with the well-known deconvolution method Lucy-Richardson algorithm to create Lucy-Richardson-Rosen algorithm. The Lucy-Richardson-Rosen algorithm exhibited a significantly improved performance in convergence and estimation of the solution compared to Lucy-Richardson algorithm. The Lucy-Richardson-Rosen algorithm was initially demonstrated to deconvolve blurred mid infrared images obtained from the microspectroscopy system of Australian synchrotron. Later, it was found to exhibit good deconvolution for spatially symmetric point spread functions.

In 2019, Rosen and his PhD candidate Angika Bulbul have introduced a method of using 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 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

He is also a Fellow of SPIE (The International Society for Optical Engineering) “for achievements in digital holography and coherence optics” since 2012.

Rosen holds the Benjamin H. Swig Chair in Optoelectronics at Ben-Gurion University of the Negev since 2011.

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 2005 Rosen was elected as a Fellow of the Optical Society of America (OSA, now called OPTICA), “for initiating the research of optical correlation in 3D space and introducing computer generated holography for controlling the diffraction and propagation properties of optical beams”.

Rosen was a research associate at the Rome Laboratory of Hanscom Air Force Base, Massachusetts during 1992-1993.  He then joined the Department of Applied Physics at California Institute of Technology as a Research Fellow. In 1996 Rosen joined Ben-Gurion University of the Negev as a Senior Lecturer at the Department of Electrical & Computer Engineering. He became an Associate Professor in 2000 and a professor in 2007.

Joseph Rosen was born in Haifa, Israel. Rosen began his academic studies in the Faculty of Electrical Engineering at the Technion - Israel Institute of Technology and received his B.Sc. in 1984 (with honors), and M.Sc. in 1987. He continued his studies at the Electrical Engineering Faculty of the Technion. His D.Sc. thesis on Interferometric Electro-Optical Signal Processing was received in 1992 and supervised by Prof. Joseph Shamir.
