|Maxim Gureev, Chief Technology Officer, ActLight SA|
Maxim Gureev received his M. Sc. in Physics from Moscow Institute of Physics and Technology in 2003 and his PhD degree from EPFL in 2012. From 2003 to 2007 he worked as a researcher at Andreyev Acoustics Institute, Moscow, Russia, and as a Senior production manager for digital consumer devices at Rolsen Electronics. From 2007 to 2012 he worked as a research assistant at the Ceramics Laboratory at EPFL, focusing on the research of ferroelectric materials. From 2012 he joined ActLight SA.
ActLight disruptive technology for 3D imaging is based on the Time-of-Flight (ToF) method. With this method, a depth image is obtained by measuring light propagation time. The DPD sensor delivers high optical performance which is very important in applications such as smartphones, where emitted light power is limited, and LIDAR.ActLight ToF Our dedicated ToF method offers advantages in terms of smaller pixel size, lower operating voltage and higher background light immunity.
In current 3D camera sensors, pixel scaling is limited due to complex analog circuits. The DPD's simple digital front-end allows decreasing pixel size below 5 um. Moreover, the DPD and its read-out front-end circuit are implemented on the same substrate in standard low-cost CMOS technology and do not require high voltage for its operation.

|Low-cost Far-Infrared Imaging Sensor|
|Sebastien Fabre, CEO, IRLYNX|
Sebastien created IRLYNX in 2013. Sebastien has worked as a product manager in CMOS and MEMS sensors at NXP and Tronics from 2001 to 2009 before managing the operation of a startup in silver economy up to 2013. Sebastien holds an executive MBA and Msc in electronics from polytech’Nice Sophia.
IRLYNX developed a passive infrared detection array that uses the heat that any human is emitting and transform it into electric signals. We introduce the PyrOnIc sensors. This imaging sensors offer a new solution that combines the price advantage of PIR sensor and the information added value of the array infrared imaging. It uses an exclusive, all markets licensed infrared technology with a dedicated CMOS, which is compatible with mass-market and allows very low cost. It is combined with a radically new patented optical system, comprising multiple concave mirrors. The complete optic system is a single plastic molded piece. It allows to be coherent with the low-cost imaging sensor vision while keeping the needed performance for high-volume market needs.
The PyrOnIc sensors range gives multiple selections of pixel number, a field of view, framerate and NETD performance. Its main application fields are Human Detection, Posture and Gesture Recognition, Energy Saving, Smart Building, Assisted Living and Interactive Objects.
|Single imager 3D LIDAR + 2D camera for automated cars|
Filip Geuens, CEO, XenomatiX N.V.
A solid-state LIDAR solution will be presented that outputs both 3D point clouds and 2D images. This unique LIDAR has been developed against automotive requirements and is suitable for outdoor, long-range detection and tracking of obstacles and road users. The overlay of 2D and 3D data, coming from the same imager represents inherent sensor fusion for reliable detection and ranging. Application examples will be shown.

|Dotphoton — Image compression for professional applications|
|Bruno Sanguinetti, Executive Chairman, Dotphoton AG|
Last year, more than 1.3 trillion images were taken. 4K and 8K video, 100 MPixel cameras, automotive, AI, IoT, biotech and aerospace imaging result in data too large to benefit from modern technologies such as the cloud, solid-state storage and mobile networks.
Lossy compression, such as JPEG, takes advantage of the limits of human vision and satisfies the requirements of consumers. Professionals, however, need the assurance that image information is fully preserved, and suitable for postprocessing. Dotphoton compresses raw image data by a ratio of up to 10 to 1, while satisfying the requirement of professionals:
Information retention. Dotphoton relies on accurate camera calibration and information theory to give strict guarantees that information is retained through compression. When images are the basis for medical diagnostics, scientific results, passenger safety or strategic decisions, they must be guaranteed to be free of artefacts and retain information on a per-pixel basis.
Compatibility. Dotphoton encodes its output in a number of photons absorbed by the pixel. This is a metrologically accurate physical quantity. Dotphoton-certified algorithms give accurate results with data from any Dotphoton-certified camera. This is particularly important for AI and critical applications.
Trust. Professional image data has immense value. Generating and maintaining the users’ trust is critical to the adoption of a compression technology. It is Dotphoton’s mission to establish its brand as a symbol of quality and reliability in the Swiss tradition, and give users the peace of mind that Dotphoton-certified data and algorithms may safely be trusted.
To achieve this goal, Dotphoton relies on techniques developed for quantum physics research. Thanks to recent advances in commercial sensor technology these techniques are now applicable to a wide range of devices.

|mmWave imaging: more than radar|
Maarten Tytgat, Chief Business Development Officer, Tusk IC
Maarten Tytgat obtained his MSc. and PhD in Electrical Engineering from the KU Leuven, where he specialized in CMOS millimeter-wave receivers. In 2014 he joined Alcatel-Lucent Bell Labs in Antwerp (B), where he worked on high-speed transceiver circuits in CMOS for 10 Gbps copper access technologies. In 2016, he moved to New Jersey (USA), to work at the Nokia Bell Labs headquarters in Murray Hill, where he focused on SiGe millimeter-wave ASICs for coherent optical communication.
In 2018, he co-founded Tusk IC, a fabless millimeter-wave IC design house in Antwerp. Tusk IC provides ASIC design services for millimeter-wave circuits in silicon technologies, with applications ranging from 5G to automotive radar and millimeter-wave and terahertz sensing. At Tusk IC, Maarten actively works on the design of ASICs and takes a role as Chief Business Development Officer.
The advancements of in silicon semiconductor technologies have enabled chips to generate frequencies far into the millimeter-wave spectrum (30GHz-300GHz) and beyond. While automotive radar (76GHz-81GHz) receives a lot of industry attention at the moment, the possibilities of mmWave imaging go beyond radar: dielectric sensing, spectroscopy, gas detection, contactless water concentration measurements and quality control are some of the many applications that utilize these high-frequency waves. Thanks to silicon technologies, these imaging solutions can now be delivered in cost-effective, fully-integrated and compact chips. Tusk IC is a fabless mmWave design house that provides custom ASICs to companies that want to innovate in the mmWave spectrum.
