There is also a tutorial:

T6 Single-Photon Detection in CMOS
Matteo Perenzoni, Fondazione Bruno Kessler, Trento, Italy
Every single photon carries information in position, time, etc. Single-photon devices are now demonstrated and available in several CMOS technologies, but the needed circuits and architectures are completely different from conventional visible light sensors.

This tutorial starts from the description of structure and operation of a single-photon detector, and it continues on the definition of circuits for the front-end electronics needed to efficiently manage the extracted information, addressing challenges and requirements. Then, it concludes with an overview of the different architectures that are specific for each application field, with examples in the biomedical, consumer, and space domain.

One of the forums has Sony presentation on compressive sensing:

Compressive Imaging for CMOS Image Sensors
Yusuke Oike, Sony Semiconductor Solutions, Atsugi, Japan

And F3 forum has two more presentations:

What’s the Best Technology and Architecture for your Time of Flight System?
David Stoppa, ams AG, Rueschlikon, Switzerland

Optical Phased Array LiDAR
Michael Watts, Analog Photonics, Boston, MA

    In another forum (F3) David Stoppa will give a talk about optimum ToF choices.

    1. Thanks, added this too. Incidentally, F3 forum also has OPA Lidar presentation, apparently based on Globalfoundry new photonics platform. It allows integration of beam forming and/or scanning onto a silicon chip, together with image sensor. I'm not sure that Lidar is a good application for that, but it's quite an interesting capability.

  2. Can someone explains the significance of Panasonic's paper? What is the dynamic range in terms of EV equivalent to "450ke- Saturation Signal"? TIA.

    1. Panasonic published several papers with organic films in 2016 and 2017 ISSCC; the array size was about 2MP. This time it is 33MP ...

    2. Well, if we have 450ke saturation and the read noise similar to current m43-cameras (5-10e) then the DR is around 16EV.
