the 'exposure time' for a DAD detector is quite an intuitive concept. for instance one could consider it to be similar to the exposure time of a camera, for practical purposes. however I still fail to understand its real meaning.
what i know about the 'exposure time' of a diode array detector, is that it is the time between two current reading of a diode. I got this explanation from somebody of Waters technical support. he also told me that current that is measured is a 'recharging current'. so what i understood is that light induces some kind of change of the diode, and a current is necessary to bring the diode back to its primitive status; the more light hit the diode, the more current is necessary to re-equilibrate the diode. right? can anybody explain me a little bit better the mechanism of the recharging current and exposure time?
