Double-Wavelength Laser Scanning Microphotometer (DWLSM) for In Vitro Hair Shaft and Surrounding Tissue Imaging

摘要

The double-wavelength laser scanning microphotometer (DWLSM) with high spatial resolution had been developed for in vitro measuring of hair shaft and follicle absorbance. The instrument allows for determine the absorbance distribution across and along hair shaft and follicle. The instrument is based on standard universal binocular microscope. The construction of the instrument and the data processing reduces the influence of the light scattering on the hair and tissue samples.
