The ToF pixel includes an APD and an in-pixel circuit that integrates weak input signals to enables the 3D range imaging 250 m ahead. The sensor resolution is said to be the world's highest 250,000 pixels for a sensor based on electron-multiplying pixels. This high integration is achieved through the lamination of the electron multiplier and the electron storage as well as the area reduction of APD pixels.
The key innovative technologies are:
- The area of APD pixels is significantly reduced while the multiplication performance is maintained through the lamination of the multiplier that amplifies photoelectrons and the electron storage that retains electrons.
The APD multiplication factor is 10,000. - Long-range measurement imaging technology
viewing angle in figure 6 is quite low, only about 5degrees (assuming 5m length of car in 200m, i.e. approximately 20m observed area in 200m).
ReplyDeleteAPD with gain of 10000, would that be a linear APD or Geiger mode / SPAD?
ReplyDeleteThe technology shoud be the one presented at ISSCC 2016:

This is a constant news entry by Panasonic, yet in 2020 we don't see a mass produced unit on the market money can buy so we resort to other solutions like LiDARs by Velodyne.
