Photometry

	Densitometry
	Fluorometry
	Nephelometry and Turbidimetry - Chemical analysis based on the phenomenon whereby light, passing through a medium with dispersed particles of a different refractive index from that of the medium, is attenuated in intensity by scattering. In turbidimetry, the intensity of light transmitted through the medium, the unscattered light, is measured. In nephelometry, the intensity of the scattered light is measured, usually, but not necessarily, at right angles to the incident light beam.
	Spectrophotometry - The art or process of comparing photometrically the relative intensities of the light in different parts of the spectrum.
