Registrations Open for Harvest Imaging Forum (Apr 5-6, 2023)
When: April 5 and 6, 2023
Where: Delft, the Netherlands
Forum Topic: Imaging Beyond the Visible
Speaker: Prof. dr. Pierre Magnan (ISAE-SUPAERO, France)
Registration link: https://harvestimaging.com/forum_registration_2023_new.php
More information can be found here: https://harvestimaging.com/forum_introduction_2023_new.php
After the Harvest Imaging forums during the last decade, a next and ninth 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.

poLight’s paper on passive athermalisation of compact camera/lens using its TLens® tunable lens
Images defocus over wide temperature range is a challenge in many applications. poLight's TLens technology behaves the opposite of plastic lenses over temperature, so just adding it to the optics stack addresses this issue.
A whitepaper is available here: [link]
Abstract: poLight ASA is the owner of and has developed the TLens products family as well as other patented micro-opto-electro-mechanical systems (MOEMS) technologies. TLens is a focusable tunable optics device based on lead zirconium titanate (PZT) microelectromechanical systems (MEMS) technology and a novel optical polymer material. The advantages of the TLens have already been demonstrated in multiple products launched on the market since 2020. Compactness, low power consumption, and fast speed are clear differentiators in comparison with incumbent voice coil motor (VCM) technology, thanks to the patented MEMS architecture. In addition, the use of TLens in the simple manner by adding it onto a fixed focus lens camera, or inserting the TLens inside the lens stack, enables stable focusing over an extended operating range. It has been demonstrated that the TLens passively compensates the thermal defocus of the plastic lens stack/camera structure. The fixed focus plastic lens stack cameras, usually used in consumer devices, typically exhibits a thermal defocus of a few diopters over the operating temperature range. Results of simulations as well as experimental data are presented together with a principal athermal lens design using TLens in only a passive manner (without the use of its electro-tunablity) while the electro-tunability can be used to additionally secure an extended depth of focus with further enhanced image quality.

CIS market news 2022/2023
Recent Will Semi report that includes some news about Omnivision (Howell): https://tech.ifeng.com/c/8MXij5vF1lP
It is worth noting that in December 2022, Howell Group, a subsidiary of Weir, issued an internal letter announcing cost control, with the goal of reducing costs by 20% by 2023.
In an internal letter, Howell Group said, "The current market situation is very serious. We are facing great market challenges, and prices, inventory and supply chains are under great pressure. Therefore, we must carry out cost control, with the goal of reducing costs by 20% by 2023.
In order to achieve this goal, Howell Group also announced: stop all recruitments and leave without substitutes; salary cuts for senior managers; stop work during the Spring Festival in all regions of the group; quarterly bonuses and any other form of bonuses will be discontinued; expenditure strictly controlled; and some R&D projects will also reduce NRE expenditure.
Howell Group said, "These measures are temporary, and we believe that business-level improvements will occur in the second half of next year, because we have a new product layout in the consumer market, while automobiles and emerging markets are rising steadily. We will reassess the situation at the end of the first quarter of next year (2023).
