luminous reflectance meaning in Hindi
luminous reflectance sentence in Hindi
Examples
- It is important to note that the colour ( luminous reflectance ) of a material can greatly influence the measurement of reflection haze.
- Using the ISO / ASTM method therefore to measure luminous reflectance produces a reliable measurement of Y for non-metallic surfaces as the diffuse component is lambertian, i . e . it is equal in amplitude at all angles in relation to the sample surface.
- Luminous reflectance measurements, Y, are required on both the sample material and a reference white; ISO 13803 details the use of a BaSO4 standard-Barium sulphate, a white crystalline solid having a white opaque appearance and high density as this material is a good substitute for a perfectly reflecting diffusor as defined under ISO 7724-2.
