Development of an Optical System for Non-Contact Type Measurement of Heart Rate and Heart Rate Variability
Self-mixing optical coherent detection is a non-contact measurement technique which provides accurate information about the vibration frequency of any test subject. In this research, novel designs of optical homodyne and heterodyne detection techniques are explained. Homodyne and heterodyne setups a...
