    Main Results:

    • The output waveform is a scaled and broadened version of the input waveform.
    • Waveform reversal is achieved when dispersion signs are identical; non-reversal occurs with opposite dispersion signs.
    • Adjusting the temporal shutter duration impacts the output waveform characteristics.

    Conclusions:

    • The demonstrated time pinhole system offers versatile control over temporal waveforms.
    • This technology has potential applications in advanced optical signal processing and measurement.
