Accuracy of Digitized Photometric Data.

Abstract

This report documents the error analysis of the photometric data acquisition and analysis system used to process impact data collected on various AMRL impact facilities by the Biomechanical Protection Branch of the AMRL. Sources of error are identified in the data acquisition, digitizing, calibration, and digital processing phases of the total analysis system. The estimates of total error accrued in the coordinate solutions to the data from the Restraint System Dynamics (Nylon/Operational/Rigid) Comparison, the Upper Torso Retraction Study, and the -50 G sub X) Injury Protection Comparison tests are derived and presented. In the digital processing phase of the report, a frequency response function was developed for the 11-point quadratic least square smoothing technique used to compute the velocity and acceleration data. This frequency response was confirmed by applying the 11-point smoothing technique to time displacement data with known velocity and acceleration characteristics. (Author)
