4D Technology and Rizse to Explore Remote Defect Inspection Alliance

4D Technology, a subsidiary of Onto Innovation at the forefront of vibration-immune, instantaneous 3D measurements of surfaces, has announced an alliance with Rizse, a developer of specialized drones for aircraft inspection. Together, the two organizations will seek to develop an extension of 4D InSpec, 4D Technology’s popular 3D surface gauge. The new sensor will enable companies in the aerospace and defense sectors to conduct high-resolution measurements of large-scale surface features to find and quantify damage, such as lightning strikes, hail dents, or bird impacts.

Rizse is an advanced robotics and artificial intelligence company involved in the development and sale of an innovative, proprietary drone technology platform. The company also develops and deploys emerging technologies for the inspection sector, including best-in-class artificial intelligence analytics and predictive maintenance.

4D Technology uses proprietary methods to enable instantaneous high-precision 3D surface measurements in difficult environments. The company has built systems to measure telescope optics, including the James Webb Space Telescope (JWST) The JWST was measured in a cryogenic chamber with nanometer-level precision by instruments with acquisition speeds as low as 30 millionths of a second. The line of 4D InSpec handheld surface defect gauges advances aviation engine inspection by providing simple, shop-floor quantification of critical defects and component geometries.
