Harvest Imaging Forum April 5 and 6, 2023

https://harvestimaging.com/forum_introduction_2023_new.php

After the Harvest Imaging forums during the last decade, a next and nineth one will be organized on April 5 & 6, 2023 in Delft, the Netherlands. The basic intention of the Harvest Imaging forum is to have a scientific and technical in-depth discussion on one particular topic that is of great importance and value to digital imaging. The forum 2023 will again be organized in a hybrid form:

• You can attend in-person and can benefit in the optimal way of the live interaction with the speakers and audience,
• There will be also a live broadcast of the forum, still interactions with the speakers through a chat box will be made possible,
• Finally the forum also can be watched on-line at a later date.

The 2023 Harvest Imaging forum will deal with a single topic from the field of solid-state imaging and will have only one world-level expert as the speaker.

"Imaging Beyond the Visible"
Prof. dr. Pierre MAGNAN (ISAE-SUPAERO, Fr)
 

Abstract:
Two decades of intensive and tremendous efforts have pushed the imaging capabilities in the visible domain closer to physical limits. But also extended the attention to new areas beyond visible light intensity imaging. Examples can be found either to higher photon energy with appearance of CMOS Ultra-Violet imaging capabilities or even to other light dimensions with Polarization Imaging possibilities, both in monolithic form suitable to common camera architecture.

But one of most active and impressive fields is the extension of interest to the spectral range significantly beyond the visible, in the Infrared domain. Special focus is put on the Short Wave Infrared (SWIR) used in the reflective imaging mode but also the Thermal Infrared spectral range used in self-emissive ‘thermal’ imaging mode in Medium Wave Infrared (MWIR) and Long Wave Infrared (LWIR). Initially mostly motivated for military and scientific applications, the use of these spectral domains have now met new higher volume applications needs.

This has been made possible thanks to new technical approaches enabling cost reduction stimulated by the efficient collective manufacturing process offered by the microelectronics industry. CMOS, even no more sufficient to address alone the non- visible imaging spectral range, is still a key part of the solution.

The goal of this Harvest Imaging forum is to go through the various aspects of imaging concepts, device principles, used materials and imager characteristics to address the beyond-visible imaging and especially focus on the infrared spectral bands imaging.

Emphasis will be put on the material used for both detection :

• Germanium, Quantum Dots devices and InGaAs for SWIR,
•  III-V and II-VI semiconductors for MWIR and LWIR
•  Microbolometers and Thermopiles thermal imagers

Besides the material aspects, also attention will be given to the associated CMOS circuits architectures enabling the imaging arrays implementation, both at the pixel and the imager level.
A status on current and new trends will be provided.
 

Bio:
Pierre Magnan graduated in E.E. from University of Paris in 1980. After being a research scientist involved in analog and digital CMOS design up to 1994 at French Research Labs, he moved in 1995 to CMOS image sensors research at SUPAERO (now ISAE-SUPAERO) in Toulouse, France. The latter is an Educational and Research Institute funded by the French Ministry of Defense. Here Pierre was involved in setting up and growing the CMOS active-pixels sensors research and development activities. From 2002 to 2021, as a Full Professor and Head of the Image Sensor Research Group, he has been involved in CMOS Image Sensor research. His team worked in cooperation with European companies (including STMicroelectronics, Airbus Defense& Space, Thales Alenia Space and also European and French Space Agencies) and developed custom image sensors dedicated to space instruments, extending in the last years the scope of the Group to CMOS design for Infrared imagers.
In 2021, Pierre has been nominated Emeritus Professor of ISAE-Supaero Institute where he focuses now on Research within PhD work, mostly with STMicroelectronics.

Pierre has supervised more than 20 PhDs candidates in the field of image sensors and co-authored more than 80 scientific papers. He has been involved in various expertise missions for French Agencies, companies and the European Commission. His research interests include solid-state image sensors design for visible and non-visible imaging, modelling, technologies, hardening techniques and circuit design for imaging applications.

He has served in the IEEE IEDM Display and Sensors subcommittee in 2011-2012 and in the International Image Sensor Workshop (IISW) Technical Program Committee, being the General Technical Chair of 2015 IISW. He is currently a member of the 2022 IEDM ODI sub-committee and the IISW2023 Technical Program Committee.
