The only efficient optical spectrum measurement in infra-red range for low light regime is based on time multiplexing. Typically low timing jitter of the single photon detector combined with fast and high precision electronics is used for photon arrival time measurement. The timing histogram can be used to determine the spectrum of the photons. The better time detection accuracy allows to obtain the more precise spectrum information. This paper proposed an optical method for the sub-picosecond time-to-digital converters characterization prefer to optimize the multi-tapped delay lines implementation process, thus yielding the converters with much improved parameters.
