NON-LINEAR DATA ACQUISITION

摘要

One or more techniques and/or systems described herein implement, among other things, a parabolic curve for a ramp signal (310) in a data acquisition component (200), where the curve can be effectively calibrated and used to provide a settling period (304) to mitigate noise. That is, a ramp generator (206) can generate a ramp signal (310) that has a parabolic voltage curve with two substantially mirroring halves (354, 356). A comparator (210) can compare a first portion of the parabolic voltage curve (356) with a voltage signal (308) indicative of a number of photons detected by a detection array (1 18). A second portion of the parabolic voltage curve (354) is used as a temporal delay so that circuitry, such as the ramp generator (206), can settle.
