Abstract

An optical spatial filtering velocimeter that measures the velocity of a high-voltage circuit breaker is proposed. We examined the velocimeter theoretically and obtained the requirements for spatial filters (SFs), such as the transmission function. Theoretical analyses and experiments show that the sinusoidal transmission function spatial filter (STSF) provides a higher signal-to-noise ratio (SNR) and better accuracy than the traditional rectangular transmission function spatial filter (RTSF). Experiments show that spatial filtering velocimetry (SFV) with an STSF can yield better measurement results than those produced with an RTSF.
