Practical Considerations for Accurate Measurements with DIC
Selecting Lenses And Other Optical Components For Specific Experiments
Identifying And Employing Appropriate Digital Cameras
Configuring And Locating Each Component In The Imaging System
Arranging The Lighting Components
Determining The Appropriate Patterning Approach And Speckle Size
Choosing appropriate exposure time
In Section 10.1, practical suggestions regarding general imaging considerations are provided. These include (a) depth of field and field of view, (b) image artifacts that may affect measurement accuracy, (c) subset patterning and (d) exposure time. In Section 10.2, issues related to 2D-DIC measurements that are discussed include (e) out-of-plane motion (f) high magnification and depth of field and (g) measurement accuracy. In Section 10.3, issues related to 3D-DIC measurements that are discussed include (h) camera selection, (i) system configuration and specimen positioning, (j) calibration and (k) measurement accuracy.
