Popis:	A neutron spin echo experiment for tiny samples with high energy resolution can be realized by combining modulated intensity by zero effort (MIEZE) technique and ellipsoidal neutron focusing supermirrors. We observed TOF–MIEZE (the time-of-flight method with MIEZE) signals with an effective frequency of 108 kHz with focusing beam. The Fourier time range 0.48–5.3 ns was covered at once by using TOF technique with neutron wavelength 0.65–1.45 nm. The contrasts of TOF–MIEZE signal were 0.62 ± 0.02 and 0.50 ± 0.05 with each neutron wavelength of 0.68 nm and 1.35 nm, respectively.
