Abstract
A method for spectrum analysis of human blood flow Doppler signals with an amplitude modulated grating as a time-spatial converter is reported. The experimental results are consistent with the theoretical analysis. This method possesses the advantages of fast multichannel parallel processing and large capacity. The facilities are simple and compact.
