LMI Seminar: From Tunable Devices to Self-Calibrated Micro-Spectrometers: The Rise of Computational Optical Sensors
Dr. Doron Naveh, Faculty of Engineering, Bar-Ilan University
Abstract:
The progress in spectral measurement of light is central to the advancement of scientific research and for future technologies. Spectrometers, optical devices that measure the spectral component of light, are important tools for modern applications including chemical sensing, spectral imaging, and light source characterization [1-3]. Distinct from conventional spectrometers, computational spectroscopy necessitates the use of bulky components or moving parts [4,5] and is based on compact photodetector devices. In this talk I will survey the topic of computational spectrometers and their future applications. The role of machine-learning algorithms and computational approaches will be discussed firefly as well as the importance of van der Waals materials and heterostructure devices.
