9D Ladar from API incorporates a new technology that has been designed to for automated production measurements. The patent-pending Dynamic 9D Ladar offers the world’s first interferometry-based Ladar system incorporating Optical Frequency Chirping Interferometry (OFCI) technology.

IMTS will mark just the second time 9D Ladar has been shown at a North American trade show after CMSC in July. 9D Ladar will be available for demonstration every day in the booth, showcasing its applications for automated inspection for automotive and aerospace manufacturing and assembly.

9D Ladar’s accurate data collection of production measurements represent the next generation dimensional inspection solution, replacing traditional, off-line, large volume coordinate measuring machines (CMM) and near-line and in-line inspection solutions using both optical laser-line and structured light scanning sensors.

The two-axis 9D Ladar system processes measured data at the impressive rate of 20,000 points per second and with scanning speeds of 0.2 seconds/cm2. Furthermore, 9D Ladar’s high Dynamic range is insensitive to target reflectivity, can measure translucent materials, and is able to measure target features with up to an 85° incidence angle. High-density raster scanning delivers up to 50 lines/second, with 0.1 mm line spacing. 9D Ladar’s on-board scale reference system delivers unparalleled 2D and 3D accuracies of just 6 µm/m providing comparable accuracies to benchmark accuracy large volume CMMs.

Dynamic 9D Ladar’s compact design, weighing just 10.4 kg, incorporates an integral controller with ethernet communication, allowing for seamless integration to both portal CMM frames or 6-axis industrial robots, including 7-axis rail mounted configurations.

9D Ladar’s iVision smart camera system provides instant part visualization for automated scan path planning, providing both automated feature and targeted region measurement, along with remote measurement operation viability.

API’s Dynamic 9D Ladar delivers X, Y, Z, I, J, K data for each generated cloud point along with the addition of R, G, B data allowing for scanned data to be imaged directly onto the captured camera image. This unique capability allows display of characteristics with distinct background colour contrast, surface vectors, surface roughness etc., which are difficult to isolate with only the standard 3D point cloud data.
