Nowadays, CMOS Image Sensors occupy an increasingly important place. Thus, our ISAE-SUPAERO team has been developing CMOS image sensors for several years with many players in the field, and innovates by proposing new architectures and conditions of use requiring studies relating to elementary components but also on more complex structures.
Measurements are then performed on transistors, diodes with the help of a probe tester and a parametric analyzer, allowing very low current measurements (10 aA). Similarly, simple structures containing innovative pixels can be operated with the tester by means of probe cards coupled with a data generator specially designed for image sensors. All these studies make it possible to better understand the physics of photo-detection, but also to constitute models for our simulators. They are also used to follow the manufacturing processes during the various productions.

ISAE-SUPAERO - as a center for training through #research, research training and innovation - has many research equipments used within its 6 research departments.
Today, we present the cryogenic electrical tests facilities!
The ISAE-SUPAERO Image Sensor Research Group (CIMI) is studying sensors in the field of visible wavelengths but also for different spectral domains such as InfraRed (IR). The detection of these longer wavelengths (SWIR to LWIR) requires materials other than silicon for detection, associated with a silicon readout circuit for information processing, all operating at cryogenic temperature.
In this context, ISAE-SUPAERO has developed electrical and electro-optical characterization setups operating at low temperature for microelectronic circuits in order to extract and model the behaviours and performances of these circuits. These characterization setups allow to address both very simple devices, such as transistors, as complex components (complete image sensor) up to 120 inputs/ outputs.

ISAE-SUPAERO - as a center for training through #research, research training and innovation - has many research equipments used within its 6 research departments.
Today, we present the P68 research aircraft!
Since 2018, the ISAE-SUPAERO Air Operations Center has been equipped with a twin-engine Vulcanair P68 Observer 2 dedicated to teaching ISAE students flight mechanics, flight test techniques, and performing research projects. This aircraft has a telemetry system to track flight parameters in real-time from the campus’ classrooms.
Multipurpose with a large payload, it can embark various sensors thanks to a hatch under the fuselage. It also has unique instrumentation for research activities and sensors for pilot monitoring (remote eye trackers, scene camera etc.) synchronized with the flight parameters. It allows to estimate pilots’ attentional and cognitive states (fatigue, distraction, inattention, engagement, etc.) in real time during the flight.

We received the visit of Professor Shine S R from the Indian Institute of Space Science and Technology (IIST) on December 7 and 8. ISAE-SUPAERO signed in 2020 a co #cooperation agreement with the Indian Institute of Space Science and Technology, and this visit was a perfect opportunity to discuss the deepening of collaborations in #training and #research between our two institutions.
ISAE-SUPAERO and IIST have already been cooperating for 4 years in the framework of Franco-Indian collaborative academic projects, involving ISAE-SUPAERO and IIST students on subjects related to space exploration missions and with the participation of experts from CNES, IRAP and the Indian space agency (ISRO)!

This video and audio show the results of NASA’s Perseverance Mars rover using its SuperCam microphone to record the sounds of a Martian dust devil – the first time any such recording has been made. The dust devil passed by on Sept. 27, 2021, the 215th Martian day, or sol, of the mission. The dust devil was estimated to be 82 feet (25 meters) wide, at least 387 feet (118 meters) tall, and moving at about 12 miles per hour (19 kilometers per hour).
At the same time that SuperCam’s microphone recorded the dust devil, Perseverance’s weather sensors (measuring wind, pressure, temperature, and dust) and the Navigation camera (Navcam) were on. This allowed scientists to combine sound, image, and atmospheric data. The unique combination of these data, along with atmospheric modeling, allowed the researchers to estimate the dust devil’s dimensions.
Capturing a passing dust devil takes some luck. Scientists can’t predict when they’ll pass by, so rovers like Perseverance and Curiosity routinely monitor in all directions for them. As scientists see them occur more frequently at a certain time of day, or approaching from a certain direction, they’ll focus their monitoring to try and catch a dust devil.
The video included here shows three rows. The top row is a raw image taken by Navcam of the Martian surface; while the camera is capable of color, it takes black-and-white images when searching for dust devils to reduce the amount of data sent back to Earth (most of the images come back without a dust devil detected).
The middle row shows the same image processed with change detection software to indicate where movement occurred as time passed by; color is used to show density of dust, going from blue (noise to low density dust) through purple to yellow. The last row is a graph showing a sudden drop in air pressure recorded by Perseverance’s weather sensor suite, called Mars Environmental Dynamics Analyzer, provided by Centro de Astrobiología (CAB) at the Instituto Nacional de Tecnica Aeroespacial in Madrid and the sound amplitude from SuperCam’s microphone.

In the frame of its research activities, ISAE-SUPAERO develops electronic components and systems for scientific and space applications. Space is a very aggressive environment, in particular because high-energy particles emitted by the sun or trapped in radiation belts threaten the health of astronauts, the properties of materials and the proper functioning of electronic chips.
In order to reproduce the effects of this ionizing radiation on electronic technologies in the laboratory, ISAE-SUPAERO has equipped itself with an X-ray irradiation chamber with an energy of up to 320 keV. This video presents a classic use of this equipment: an electronic component to be tested is placed in the irradiation chamber, the X-ray tube is powered up, and the effects on the operation of the component (here an image sensor) are observed and measured in real time.

Unmanned aerial vehicles (UAVs) and nanosatellites have numerous applications in the media, industry, agriculture and telecommunications sectors. These two types of platforms share the common constraint of embedding complex systems in a reduced volume. One of the key elements of embedded communication systems is the antenna, which must also be compact and light.
ISAE-SUPAERO, in collaboration with ENAC and ANYWAVES, is currently developing dielectric antennas made by 3D printing of ceramics that meet the demanding criteria of integration on UAVs and nanosatellites. Thanks to the anechoic chamber available at ISAE-SUPAERO, the researchers involved in the development of these original antennas can characterize their radiation properties with precision and thus validate the new technological solutions proposed.
