Abstract

The measurement of small amplitude. high-frequency vibrations, such as occur in ultrasonic bonding tools, is accomplished by use of a light beam reflected from the vibrating surface. The amplitude of vibration of surface 1 is measured by observance of reflected light beam 2. The reflected band of light 2 is viewed through microscope 3. The width of the observed light beam is proportional to the amplitude of vibration of surface 1.
