The combination of the modulation of intensity by zero effort (MIEZE) technique and ellipsoidal neutron-focusing supermirrors enables us to perform a neutron spin echo experiment for tiny samples with high energy resolution. We successfully identified time-offlight MIEZE (TOF-MIEZE) signals for neutrons elastically scattered at the sample under a focused geometry using ellipsoidal supermirrors. The effective frequency of the TOF-MIEZE signal was 108 kHz. The Fourier time range was covered from 0.48 to 5.3 ns using the TOF technique with neutron wavelengths from 0.65 to 1.45 nm.
