Line CCDs

CCD Posted on Sun, October 16, 2022 09:41:04

Some CCDs are not 2-dimensional, but are just a single line of sensors. Typically used for scanning devices. Here is one such. Another is here.

The first one appears to be 16 bit – but what is the readout noise, and can you get line CCDs with better than 16 bit dynamic range? Second one is an 11ish bit device?

DAVIS neuromorphic camera

There is a type of camera where the sensor reacts to changes, not to ‘an exposure signal’. The DAVIS 346 Neuromorphic camera is one such.


Note the apparent high dynamic range of 120dB – like a 100-image stack from MLO?


How can we use an ‘event-based camera’? Can the camera also be triggered from outside?
