MC3.1 - NEXT GENERATION INFRARED TECHNOLOGY
Abstract
Abstract
The imaging technology including materials, detectors, optics and imaging system design have dramatically improved over last decade. In this presentation new directions toward infrared imaging with a future perspective will be discussed.
MC3.2 - Dispersion engineered metasurfaces for broadband achromatic optics
Abstract
Abstract
Chromatic aberrations in lenses are challenging to correct over large bandwidth. We show that dispersion-tailored and polarization-insensitive metasurfaces comprising counterintuitive anisotropic nanofins can correct the chromatic aberrations simple singlet lenses to sophisticated microscope objectives with unprecedented compactness.MC3.3 - WAVELENGTH MODULATION SPECTROSCOPY ENHANCED BY MACHINE LEARNING FOR EARLY FIRE DETECTION
Abstract
Abstract
We proposed and demonstrated a new machine learning algorithm for wavelength modulation spectroscopy to enhance the accuracy of fire detection. The result shows more than 8% of accuracy improvement by analyzing CO/CO2 2f signals.

This paper presents a technique to use deep neural network on data analysis of distributed acoustic sensing (DAS) system built by phase-sensitive optical time-domain reflectometry (Φ-OTDR) with Rayleigh enhancement.
MC3.5 - 25 GHZ BANDWIDTH HIGH SPEED PHOTODIODE FOR TWO-MICRON WAVELENGTH APPLICATION
Abstract
Abstract
This work reports a normal incident high speed photodiode operating at two-micron wavelength with InGaAs/GaAsSb type-II multiple quantum wells absorber. A 3dB bandwidth of 25 GHz can be achieved, which is, in our knowledge, the fastest photodiode at 2-micron wavelength.
