Latest Patents

One of his latest patents is a method for measuring a height map of a test surface. This method utilizes a multi-sensor apparatus that includes a pre-scan sensor and a height measuring sensor. The apparatus is designed to handle surfaces with varying reflectivity and incorporates one or more light sources to illuminate the test surface. A spatial light modulator is also included, which modulates light emitted from the sources. The method involves performing measurements to determine both an illumination intensity map and a height map of the test surface.

Another significant patent by Ketelaars is focused on the inner diameter measurement of transparent tubes. This method employs a laser beam to scan the tubular object, detecting laser light in a specific detection direction. The inner radius of the object can be calculated using various parameters, including the refractive index and scanning speed. This innovative approach allows for accurate measurements without necessarily requiring the refractive index if certain conditions are met.
