Abstract:

Some possibilities of noncontact pulse waves measurements of a person in vivo using laser speckle methods have been considered. The realisation of noncontact high-sensitive sensor was carried out by the differential scheme. The laboratory model was developed and tested, and natural measurements were taken.
