Videos tagged with Figure of Merit

This video provides an in-depth technical breakdown of night vision image intensification tubes, focusing on the specifications that actually matter to consumers. It debunks common misconceptions about 'generation' ratings and emphasizes that ambient light conditions significantly impact perceived image quality more than specific tube metrics. The discussion covers key performance indicators like Signal-to-Noise Ratio (SNR) for low-light and Modulation Transfer Function (MTF) for highlight conditions, alongside less critical specs like Figure of Merit (FOM) and Equivalent Background Illumination (EBI). The video also delves into device-level features such as bridge design, manual gain control, and external power, offering practical advice for consumers navigating the complex night vision market.

This video, presented by Ian McCollum of Forgotten Weapons, corrects previous assessments of Whitworth rifle accuracy by differentiating between 'Figure of Merit' and 'Minute of Angle' (MOA). It details the historical British military definition of Figure of Merit as mean radial dispersion and explains the statistical conversion to MOA. The corrected data shows the Whitworth's significant accuracy advantage over the standard Enfield musket in 1857, even at long ranges.
