Introduction

Lifford McLauchlan is a notable inventor based in Corpus Christi, Texas. He has made significant contributions to the field of laser technology, holding two patents that showcase his innovative approach to laser control systems.

Latest Patents

One of Lifford's latest patents is for a Closed Loop Laser Control system. This invention addresses the radiance of a laser, which is influenced by various factors such as drive current, age, and temperature. The laser projection device he developed adjusts laser drive parameters using a gradient descent operation, allowing for iterative and periodic adjustments. The timing of these adjustments can vary, being shorter or longer than a scan line in a video image.

Another significant patent is for a Scanning Mirror Control system. This system includes a scanning mirror with both fast-scan and slow-scan axes. The movement along the slow-scan axis is managed by a control system that receives position information regarding the angular displacement of the mirror. The control system operates in two loops: an outer loop in the frequency domain that determines harmonic drive coefficients, and an inner loop in the time domain that compensates for resonant vibrations of the scanning mirror.
