HS761 and HS763 Cross-Vector Laser Sensors are used exclusively for capturing gap/flush measurements as they can see around edges to accurately create a complete surface profile.
Traditional laser profilers utilize a single stripe laser stripe coupled with a single imager to capture surface scans. But a single view cannot see surface points around the radius on the edge of the gap.
Cross-Vector sensors utilize lasers angled toward the inside edges of the gap, crossing in the middle. This allows the sensor to see around edges of the radius to the vertical tangent and beyond. The result is a complete surface profile and the most accurate gap measurements.
