With a count of three patents to his name, Brown is recognized for his innovative approaches to tracking systems that utilize laser beams for enhancing accuracy in various applications.

Latest Patents

Among his latest patents, Brown's work on the **Tracking Laser Interferometer** stands out. This system is designed for accurate tracking of a randomly moving object through a laser beam, employing first and second beam steering assemblies that pivot about perpendicular and intersecting X and Y axes. The laser beam is directed along an R axis, where it is intercepted by a retroreflector attached to the moving object. This setup enables precise error signal generation, allowing motors to adjust the steering assemblies to minimize error effectively. Additionally, the system features an interferometer that determines the distance of the moving object from a reference location.

Another notable patent is the **Seam Tracking System with Acousto-Optical Scanner**. This advanced system is intended for tracking random seams on surfaces, which is crucial for processes like welding or inspection. Utilizing a laser and a scattered light detector, the system achieves high-speed seam tracking by scanning the laser beam across the seam at a rate of 170-2100 scans per second, efficiently reducing data processing time while maintaining the desired accuracy.
