A novel technique is proposed for estimating the angle-of-arrival (AOA) in free-space laser communication based on the shape of a laser beam spot on a flat surface. Two methods are introduced: one where ellipses are fitted to the intensity contour of the beam spot. and another where a least-squares fit of an AOA-dependent two-dimensional Gaussian distribution is applied to the intensi... https://fitnessgravesyardes.shop/product-category/pedal-arm-pivot/
