Industry Tutorial: On-chip filter technology enables compact, high-resolution and video-rate hyperspectral cameras
10 January 2023 10:00 - 11:00
Eastern Time (US & Canada) (UTC - 04:00)Traditional, push-broom hyperspectral cameras are based on expensive and heavy precision optics in glass. Their assembly requires extremely careful alignment and regular calibration.
To make hyperspectral camera’s more compact, it’s important to minimize the lenses and optical elements as much as possible. At the R&D hub imec, engineers succeeded in replacing the diffraction grating optics by a hyperspectral filter, directly on top of an existing commercial image sensor.
This hyperspectral filter is a thin material layer, based on the concept of Fabry-Pérot filters. One such Fabry-Pérot filter consists of two tightly spaced parallel mirror surfaces and by carefully controlling the distance between these reflecting surfaces, it is possible to make a filter that passes only a specific narrow wavelength band.
In this tutorial, we will discuss more in detail imec’s unique on-chip filter technology, its use in high-resolution (SNAPSCAN) and video-rate (SNAPSHOT) cameras, and the different applications that it enables. We will complement this with a live demo broadcasted from our demo studio at imec.
Finally, we would like to introduce our partner, Scientific Imaging, Inc. with whom we collaborate to bring our hyperspectral imaging technology to OEMs and end-users in the Americas, with applications ranging from the macro- to the micro-scale and from the inspection of materials such as food products and semiconductors to life sciences imaging.
Imec and Scientific Imaging, Inc. are looking forward to your attendance at this webinar and to helping you achieve your hyperspectral imaging goals.

Amin Abbasi
Business Development Manager, imec
Dr. Amin Abbasi received his BS and MSc in Applied Physics (Lasers) from the University of Tabriz, Iran, in 2009. In 2016, he finished his PhD degrees in ultra-high-speed directly modulated DFB lasers at Ghent University (UGent). He continued his research at imec/UGent on 100 Gb/s single-channel EAM modulators until 2017. Afterwards, he joined AntwerpSpace/OHB as Photonic Team Leader on microwave photonics for satellite communication. There, he contributed to various development projects for the space segment, such as OBF for SAR radar and Q-band frequency converter and receiver development for free-space communication. He joined imec in September 2020 as a business development manager, covering imec’s SiN/Si 200- and 300-mm photonic platforms for sensing applications. He currently focuses on photonics integrated circuits (in Si/SiN) for optical switching and optical beamforming for lidar applications. He has (co-)authored more than 50 peer-reviewed publications.
