摘要： Method of analysing at least one parameter of a body component is provided. The method includes illuminating the component or body with light of at least a first and second waveband, receiving light of at least said first and second wavebands remitted by the component at a photoreceptor or photoreceptors, and analysing the light received at the photoreceptor(s) to provide a ratio between the amount of light remitted of the first waveband and the amount of light remitted of the second waveband, and from this calculating the component parameter.

摘要： A method of obtaining a measurement of the extent of telangectasia in an area of skin is disclosed. Initially (S3-1) an image of an area of skin (2) to be analyzed is obtained. The obtained image is then processed (S3-2-S3-3) to determine blood distribution data indicative of the distribution of blood in an imaged area of skin. This blood distribution data is then converted (S3-5) using a Discrete Fourier Transform and the converted blood distribution data is then processed to obtain a measurement of the extent features in a determined distribution of blood correspond to structures of a predetermined size. The obtained measurement of the extent of telangectasia can then be combined (s3-6) with other measurements of the effects of photo-damage such as measurements of melanin disorder and collagen degradation to obtain a measurement of the extent of photo-damage.
