  journal={Sound and Vibration},
There are a variety of different noncontacting measurements that can typically be employed for developing modal test data. Digital image correlation, dynamic photogrammetry, and three dimensional (3D) laser vibrometry are all noncontacting measuring approaches that were used to obtain modal data for a candidate test structure along with traditional accelerometer measurements. Each approach has its benefits and drawbacks, so comparative measurements are made using these devices to show some of… 

Measurement of 3-D Vibrational Motion by Dynamic Photogrammetry Using Least-Square Image Matching for Sub-Pixel Targeting to Improve Accuracy

The proposed methodology only requires inexpensive daily-use cameras, and can remotely detect the dynamic displacement of a structure vibrating in a complex three-dimensional defection shape up to sub-pixel accuracy, and has abundant potential applications to various fields, e.g., remote vibration monitoring of an inaccessible or dangerous facility.

Investigation and Application of Digital Image Correlation Technology in Vibration Measurement Based on Two Cameras

This paper uses BUMBLEBEE binocular stereo cameras to shoot the images of test object, and a MATLAB program is developed to revert the coordinates of every pixel, reduce noise, and generate stereo images.

High-Precision Positioning of Laser Beams for Vibration Measurements

Predicting the vibratory response of structures with complex geometry can be challenging especially when their properties (geometry and material properties) are not known accurately. These structures

Advanced Material Properties Measurements with Optical Metrology

This paper will review microscopic analysis of crystalline behavior, coupon testing of dog bone specimens and large scale materials measurements in stamping operations, and the measurement of extreme materials properties, such as high-speed forming limit curves and deep drawing properties will be discussed.

An Experimental Investigation on Uncertainty in Measuring Vibration Deflection Shapes With Digital Image Correlation

A “Type A” evaluation of uncertainty when measuring vibration deflection shapes with DIC demonstrates a strong correlation between the deflection amplitude and the random uncertainty due to motion blur.




Laser techniques are very popular due to the non-contacting nature of this measurement device. Accelerometer measurements are also widely used in many applications but suffer from potential mass
