Patent number: 9922428Abstract: A shaker test apparatus is provided along with a method of collecting and processing images, wherein a shaker table is driving the device under test by a vibration controller at a known vibration frequency and period, wherein a device under test obtains a steady-state vibration characteristic of that excitation frequency when mounted on the shaker table. While the device under test is being excited, a trigger signal controller triggers a camera to capture a series of still image frames at a regular sampling frequency that is less than the vibration frequency (under-sampling), and a timer associated with the camera records a timestamp of an image capture time for each image frame. A computer processor uses the timestamps to remap the order of the image frames, shifting each frame's capture time backwards by a specified multiple of vibration periods in order to correctly represent a single vibration period beginning with an earliest captured image.Type: GrantFiled: August 19, 2016Date of Patent: March 20, 2018Assignee: CRYSTAL INSTRUMENTS CORPORATIONInventors: Yihao Liu, Hongjian Gao, James Zhuge, Weijie Zhao
