N2 - We developed a scheme for spin coherence measurement based on the coherent Kerr effect, which is the coherent version of the conventional complex Kerr effect, which only gives the projective spin state. In addition to the previously demonstrated tomographic Kerr rotation, which corresponds to the real part of the coherent Kerr effect, we demonstrate here a tomographic Kerr ellipticity, which corresponds to the imaginary part of the coherent Kerr effect. Using the tomographic Kerr ellipticity scheme, we show the coherent rotation, a natural extension of the conventional coherent oscillation, of the precessing electron spin under a magnetic field. We also confirm the complex relationship between tomographic Kerr rotation and ellipticity by measurement of the coherent Kerr spectra.
