WebMar 2, 2024 · This type of optical filter is also known as anti-aliasing or blur filter and it was designed by camera manufacturers to eliminate the problem of moiré (wavy patterns with … WebAn anti-aliasing filter (AAF) is a filter used before a signal sampler to restrict the bandwidth of a signal to satisfy the Nyquist–Shannon sampling theorem over the band of interest. Since the theorem states that unambiguous reconstruction of the signal from its samples is possible when the power of frequencies above the Nyquist frequency is zero, a brick wall …
WebPlease note however that we also supply conventional birefringent optical anti-aliasing filters and optical low-pass filters.) Color aliasing persists as a difficult problem in digital imaging.
