| 20090080727 | METHODS AND APPARATUS FOR QUANTIFYING PHOTO-DAMAGE - A method of obtaining a measurement of the extent of telangectasia in an area of skin is disclosed. Initially (S | 03-26-2009 |
| 20090080726 | METHOD AND APPARATUS FOR MEASURING COLLAGEN THICKNESS | 03-26-2009 |
| 20090043363 | METHOD AND APPARATUS FOR MEASURING SKIN TEXTURE - Among various methods, apparatuses, and media, recording media having executable instructions are provided for measuring skin surface texture. One such execution of instructions can process an obtained first measurement of light utilising a model of the interactions of light with chromophores present in skin to determine variations in returned light levels arising due to variations in levels of illumination. Execution of such instructions can utilise a difference between the obtained first, and an obtained second measurement of light returned by an illuminated area of the skin and determined variations in returned light levels arising due to variations in levels of illumination, to obtain a measurement of the surface texture of the illuminated area of the skin. | 02-12-2009 |
| 20080319283 | METHOD AND APPARATUS FOR MEASURING SKIN TEXTURE - Among various methods, apparatuses, and media, a number of methods are provided for measuring skin surface texture. One such method includes illuminating an area of skin with polarized light, and obtaining a measurement of light returned by the illuminated area of skin in a first and a second waveband. The method includes processing the measurement of light in the first waveband to determine an estimated expected level of light in the second waveband returned by the illuminated area of skin utilising a model of the interaction of light with at least one chromophore in the skin. A measurement of the surface texture of the imaged illuminated area of skin can be determined on the basis of a difference between the estimated and actual levels of light in said second waveband returned by the illuminated area of skin. | 12-25-2008 |
