STUDY OF BIOLOGICAL OBJECTS BY THE GEOMETRIC OPTICS METHOD
Annotation
Biological objects are investigated by the method of geometric optics. Optical scheme of developed device is shown, in which an axicon pair of conical lenses is used. A triangulation method is described, the relationship of the aperture angle of illumination and the angle of observation with the measurement error is given. A way to increase the measurement range is found. The measurement error with the presented device is not higher than 0.1 µm, and the measurement range is 0–100 mm. Metrological data obtained from experiments with human skin samples of different age groups are described.
