Synopsis The electron displacement induced by an ultrashort pulse is theoretically investigated. We propose and numerically demonstrate a scheme to accurately measure the electron displacement using a ruler formed by the interfering spirals in the photoelectron momentum distribution generated by two oppositely circularly polarized pulses. It can be understood as a temporal double-slit with an additional spatial shift on one slit.
