The IAP of the Engineering Faculty invites the faculty students and staff to attend the seminar:

On coherent imaging, incoherent imaging, and "in-between" imaging: Reality - it turns out - is slightly more complicated

(the lecture in Hebrew)

Room 108, Wolfson Building for Mechanical Engineering

Shahar Gov, Ph.D.

Senior Research Scientist

Abstract:

Practical imaging systems are neither completely coherent, nor completely incoherent. At the majority of cases, they even contain cascade of numerous imaging systems, not just one, as is usually depicted in this course. This lecture presents a practical yet rigorous approach to these types of systems containing:

·         A mathematical description of the sample in terms of a scattering matrix.

·         A follow-up of the signal along the double-imaging system (from source, through sample towards the detector) and arrival to an expression describing the signal at the detector as a function of the optical properties of the system and the sample.

·         An exploration of the expression, and extraction of some interesting conclusions on these types of systems, that might look surprising at first look.

·         Some limiting cases of this expression and the physical logic that support their validity.

·         Presentation of experimental evidence that corroborates the mathematical model.The lecture is most suited for undergraduate students, having a good understanding of how an ideal imaging optical system works in terms of planewaves.  

Dr. Shahar Gov:

Has a B.Sc. in Electrical Engineering from the Technion, and an M.Sc and Ph.D in applied physics from the Weizmann Institute. He joined Nova Measuring Instruments in 1999 as a senior system engineer, where he participated in the development of a Spectral reflectometer for measuring critical dimension optically (OCD) at the semiconductor industry. Later on he became manager of the system group, whose main focus was in designing, developing and testing concepts for OCD measurements of next generation's structures. Today he works as a senior research scientist as part of the CTO group, developing and testing concepts and models of Nova’s potential future technologies.

The IAP promotes the dialogue between the Faculty and the Industry, by providing the platform on which both can engage in areas such as R&D, students’ internship and recruitment, activation of knowledge transfer processes by Ramot and more.
