摘要：
A dual-arm optical interferometer with a narrow-band ultrasonic light modulator in one of the channels is described. This apparatus provides sinusoidal modulation of the light field intensity at the input of the photodetector over a broad band of temporal frequencies. This makes it possible to avoid the use of the wide-band optical modulators necessary in traditional methods of measuring the amplitude-frequency characteristics of photodetectors. Experimental results are presented.
