Latest Patents

John P. Sharpe holds a patent for a "System method and apparatus for optical directional determination." This invention outlines a method for measuring the direction and velocity of a target within a measurement volume in a laser Doppler velocimetry system. The process involves selecting discrete grating positions for an electrically switchable grating and placing it in the light path of a laser source. The laser outputs a beam along this path, and the grating is switched through its positions at a specific frequency to generate diffracted light beams. These beams are then focused on a measurement volume where a target passes, allowing for the detection of scattered light and the calculation of the power spectrum of light intensity fluctuations. The maximum peak in this spectrum corresponds to the target's velocity and direction.
