DESCRIPTION:Optical spectroscopy is widely used in non-contact materials an
 alysis. Although laboratory bench-top spectrometers offer excellent resolu
 tion\, range and sensitivity\, their miniaturization is crucial for portab
 le applications demanding indicative but instantaneous results. Among the 
 recent developments in scaled-down spectrometers\, an increasingly popular
  strategy is to use ‘reconstructive’ or ‘computational’ algorithm-
 based devices. Typically featuring spectral encoders with known optical re
 sponses\, the measured electrical signals in such devices are combined to 
 ‘approximate’ the incident spectrum through these algorithms. I will p
 resent an evolution of spectrometer miniaturization over the past 30 years
  and give examples of such disruptive concepts shaping future device techn
 ologies.\n\nSpeaker(s): Professor Tawfique Hasan\n\nRoom: Amphi 2 \, Telec
