Description
Summary:This paper presents the state of the art of the Integrated Streak Camera (ISC) architectures in standard CMOS technology. It focuses on some of the methods required for reconstructing the luminous events profile from the chip raw data. Two main ISC architectures are presented. The first adopts the traditional for the most silicon imagers pixel array configuration, where the photocharges-induced signal is processed directly in-pixel. The second approach is based on a single light detecting vector, comparable to the slit of a Conventional Streak Camera (CSC), coupled to an amplifier stage and an analog sampling and storage unit. For both architectures, depending on the on-chip processing of the photocharges, appropriate signal reconstruction techniques are required in order to restore the luminous signal shape. A novel single vector ISC front-end architecture with an asynchronous photodiode reset scheme is presented. Algorithms allowing the luminous event reconstruction are proposed and validated through simulations for all the ISCs considered.
