Action Item 2: Evaluate and re-certify the accuracy of the laser scanner to the correct standard with all software modifications incorporated and include in this analysis a side-by-side comparison of the laser measurements of actual back-face deformations with those taken by digital caliper to determine whether laser measurements can meet the standard of the testing protocols

The committee spent considerable time with ATC and NIJ-certified commercial testing labs to better understand the advantages and disadvantages of the digital caliper and the laser scanner. See Chapter 5 and Appendix M.
