Led a cross-functional team to implement and test a prototype 6 degree of freedom (6DOF) measuring system for laser trackers based on imaging the dihedral lines in a cube-corner type retroreflector.

Derived a closed-form mathematical solution for the rotation matrix of a cube-corner type retroreflector that is illuminated with a laser and imaged with a special purpose digital camera.

Created a new machine vision algorithm for identifying lines in a digital image and measuring their angles to metrology-level precision. A U.S. patent was awarded for this work.

Conceived self-compensating angular encoder concept, and led cross-functional team to implement the new design. Eliminated a problematic, time-consuming manual production procedure bottleneck and produced a recurring savings of $600,000 per year.

In 2011, FARO Technologies, Inc. (NASDAQ: FARO), a market leader in the field of dimensional metrology, was faced with a critical production problem. The laser tracker product line was rapidly gaining in popularity due to its attractive combination of small physical size, relatively low cost and high accuracy. Unfortunately, like many low volume precision scientific instruments, the manufacturing process was slow and labor intensive, and the reject rate in quality assurance tests was far too high, approaching 50% at times. Something had to be done to keep up with the ever-increasing sales volume, but achieving high volume production for a high precision measuring instrument is no small challenge.

Formulated and proved a mathematical theorem which governs the behavior of angular encoders. This theorem enables the creation of self-correcting angular encoders which are stable to less than 1 arcsecond over extended periods of time.

Developed a new method for compensating PSD devices based on high speed measurements to eliminate noise caused by atmospheric turbulence.

Developed accelerated smart warm-up technology for laser trackers for a major aerospace customer. This technology halved the warm-up time, increased accuracy and improved customer’s production throughput by 15%.

Developed Kalman filter for high precision LIDAR distance measurement system which reduced noise levels by a factor of 3.

At FARO Technologies Inc, designed an automated system for ASME B89.4.1 compliant calibration of laser trackers and led a cross-functional team to implement the design and put it into use. New approach provided a recurring cost savings of $550,000 per year.

At FARO Technologies Inc, developed heuristic algorithm for focusing laser tracker optics. Implemented Java software to automate the measurements and direct focus adjustments. Improved manufacturing throughput by 25%, increased tracker accuracy and reduced manufacturing costs by $250,000 per year.

At Spatial Metrix Inc, developed suite of laser tracker compensation algorithms and applications.

At Spatial Metrix Inc, developed mathematics for self-compensating laser tracker and associated Java application.
