Abstract

PURPOSE:To ensure a direct reading of the intensity for the ghost signal without receiving any effect of the high frequency phase, etc., by using a video ghost whi which higher by 1.25MHz than the central frequency of the amplitude modulation wave for the fixed-quantity signal which shows the relative intensity (D/U) to the main signal.
