Zusammenfassung:The invention provides a time domain stealth switch and a time domain stealth device based on a light intensity modulator. According to the scheme, the time-domain stealth switch is driven to be turned on in the time-domain stealth window through the control signal, so that the time-domain stealth switch divides the detection light signal into a path of light signal without light in the time-domain stealth window and a path of light signal with light in the time-domain stealth window. Then a third light intensity modulator enables the light signal without light in the time domain stealth window to act with the event signal so as to hide the event of the event signal in the time domain stealth window. An optical power combiner combines the optical signal with light in the time domain stealth window with the optical signal output by the third light intensity modulator so as to fill an optical gap in the time domain stealth window and achieve the stealth purpose. According to the time domain stealth device, the
