Traditional rotary saturation based methods requires triggered
phases to create a robust signal change, which may not be satisfied in practical
application. In this work, based on the analysis of magnetization in the double rotating frame, we proposed detecting the signal fluctuations of proposed SLOE
method by manipulating TRs, which needs no triggering. Further, a
spectral statistical test in the frequency domain was proposed and verified, which featured an enhanced
detection sensitivity than that of deviation test.
