About This Webinar
VIS-SWIR sensors and cameras using quantum dot technology offer a wide spectral range from 400-2000nm, with tunability in its peak response across the spectrum. A high dynamic range for optimum imaging performance is useful for machine vision applications such as inspecting pharmaceutical packaging and detecting moisture at 1940nm.

Tri-band detectors can simultaneously image within the visible, SWIR, and thermal bands using one focal plane array. Such cameras require custom lenses and filters working in three bands simultaneously. These detectors incorporate super-pixels and can enable multiple imaging solutions using one camera instead of using multiple cameras.

Haque focuses on the VIS-SWIR imagers using quantum dots and their applications as well as introducing the concepts of tri-band imagers.

About the presenter

Samiul HaqueSamiul Haque, Ph.D., is a senior product manager and one of the co-founding staff at Emberion. He focuses on the commercial aspects of Emberion, dealing with product specification and variants, marketing, and application domains of SWIR and thermal sensor-based cameras using quantum dots. He is additionally managing the IP portfolio of the company.

Before joining Emberion, the independent spin off from Nokia 2016, Haque worked in various multidisciplinary areas of R&D at Nokia technologies as a senior researcher. He led projects related to flexible and stretchable electronics, touch sensors, designed novel RF antennas, and graphene-based sensors. He has worked on multiple novel techniques of developing graphene devices using printed electronics. His background is in nanomaterials and nanodevice fabrication and characterization of sensors and devices. In addition, he has filed over 40 patents in the relevant field and published in international journals and trade press. He has a doctorate in electrical engineering from the University of Cambridge, United Kingdom, where is work was related to CMOS Gas sensors using carbon nanotubes.
