What is specification of a suitable data logger for recording data from a photo sensor switch for a single shot event completing in few microseconds?

05 May 2019 1 2K Report

In an impact testing pneumatic gun the projectile perforates the target of various material in few micro seconds.

Photo sensors (photoelectric switches) are being used for recording time for measuring velocity before and after perforation

A data logger is required to measure the time precisely in micro seconds for different events.

You can use usual oscilloscope. The memory depth of it however becomes important. E.g. this one has 40thousand points:
