High Dynamic Range Imaging (HDRI) Upgrades Inspection Results

HDRI features capture details when the environment, or the objects themselves, are both bright and dark. Designers and operators of automated inspection systems have long been challenged with completing accurate inspections when those tasks required high dynamic range, or when there was a need to capture critical details in objects or environments with high contrast between their brightest and darkest areas.

The Strain Gauge Gets an Upgrade

The strain gauge, a device commonly used in the aerospace industry to detect stress and deformation, has its limitations. The three copper wires of the strain gauge often lead to labor-intensive efforts; a large, complicated structure requiring 100 strain measurements, for example, means 300 lead wires. As the implementation becomes more complex, the wire bundle itself gets bigger and heavier. Strain gauges are also susceptible to electronic magnetic interference, and the sensors must be spaced out at distant intervals.
