Jitter, the undesired fluctuations in the pointing of a laser beam due to environment or structural interactions, reduces the intensity of the beam at the target, whether the beam is used as a …

Spot jitter results from motion of designator or beam developed by designator around the intended aim point. Attenuation is a portion of the laser beam that is scattered by obscurants along the …

The results show that the spot jitter is stronger when the laser is transmitted over rock, compared to transmission over water, and that spot jitter below 25 Hz can be restricted by closed-loop …

An experimental laser jitter control testbed, equipped with fast steering mirrors to correct the beam, has been developed to test various control techniques on vibrational induced jitter.

Feb 26, 2024 · The link between the spot-size and timing jitter will allow the understanding of tolerancing for the alignment of Si-SPADs within free-space QKD receiver systems—an …

The laser spot size should be determined by a compromise between the maximum achievable charge and the minimum achievable transverse normalized emittance, which increase …

Aug 15, 2023 · To this end, a double peak adaptive threshold waveform extraction method combined with grayscale gravity method is proposed for spot centering algorithm, which …

Changes in spot size and spatial position can result from atmospheric turbulence and pointing and tracking errors. Here, An empirical analysis of that relationship is presented utilising a large …

Apr 1, 2013 · Given a noisy measurement of the laser spot in a laser pointer interaction system, the goal of the EKF method of jitter compensation is to produce a smoothed cursor position …
