Caeleste will present a paper at the CNES Image Sensor Workshop

On November 16th and 17th, the French space agency CNES, together with ESA, ISAE, Airbus D&S, Thales-Alenia Space and Sodern, is organizing a prestigious workshop on high-performance image sensors and radiation effects. The first day (16/11) will be devoted to “Radiation effects on opto-electronic detectors”, while the second day (17/11) will focus on “Photon counting, low flux and high dynamic range opto-electronic detectors”. More than 300 specialists from Europe and beyond, will discuss recent results and future trends for image sensors in space missions. Caeleste will contribute with 2 papers. On the first day Caeleste will present its radiation hardened design data base as well as the effects of radiation on image sensors realized in that technology. We will focus especially on the differences in behavior between ionizing and non-ionizing radiation.

The blue dots and circles show the effect of ionizing radiation on dark signal, while the red dots and circles are the effects of non-ionizing radiation (electrons in this case).  The difference in behavior between the photodiode itself and the sense node will also be explained.

On the second day Caeleste will present its new, patented technique to combine the best of both worlds:

 Photon counting under low-flux conditions.

 Integrating charge packet detection under high flux conditions.

In this way a photon shot noise behavior can be guaranteed from the first detected photon till the last photon before full well. The circuit on the right shows the combination of a pulse shaper for the single photon detection, combined with a current integrator for higher flux conditions.

Caeleste will be present on the prestigious Image Sensors Conference .

Caeleste will have a booth and will demonstrate its large full well sensors for low contrast imaging. Caeleste staff is available to discuss your needs in the field of advanced image sensors, (hyper) spectral image sensors and life science sensors. For a more in-depth discussion with our Business Development Manager Jan Vermeiren , please make
an upfront appointment.

Caeleste paper
Ajit Kumar Kalgi, senior design expert at Caeleste, will also present a paper called: “Photon shot noise limited image sensors with Global shutter and linear high dynamic range”.

Dynamic range (the ratio of full well capacity over the noise floor), linearity and dark current are the most important parameters of a good image sensor. Quite often also a global or synchronous shutter operation is added to the list in order to avoid imaging artefacts when looking to fast moving objects, such as e.g. propellers. On the other hand all these additional features should not blow up the pixel size and should not jeopardize the fill factor of the pixel. Caeleste succeeded in integrating all the above elements in a pixel pitch of 6.5 µm. The design and the results will be discussed in depth during the conference, but we give you three images as a teaser.

Photon shot noise limited image sensors with Global shutter and linear high dynamic range

The left image shows the scene in high gain; the propeller blades shows some blur, but the shape is not deformed, as you could expect from a rolling shutter device. The middle image is the low gain image. The right image is the combined high-low gain image after a logarithmic transform to enhance both dark and light features in the image. Please take into account that the high and the low gain images are acquired during the same integration time. In this way the images can be overlaid without any geometric correction.

Staff & JOBS: Looking for more exciting challenges?

In 2016, we already welcomed four new employees to reinforce our image sensor design team, as well as our marketing & sales team. We are growing fast.
