Abstract
Investigation of wavelength-specific textured background patterns in BOS imaging systems — analyzing spatiotemporal variability, contrast optimization, and background selection criteria for improved schlieren visualization in experimental fluid dynamics.
Key Results
Peak SNR = 22.8 at 550nm textured background wavelength
Peak gradient magnitude G = 52.3 (Sobel operator) at 550nm
Findings align with Bayer-filter green-channel sensitivity
Swept 400–670nm in 30nm increments across repeated trials
