A SYSTEM AND A METHOD FOR CONTACTLESS OPTICAL CONTROL OF HEART RATE PARAMETERS

摘要

Invention relates to cardiology and particularly to detection and registration of heart beat frequence and other parameters using contact-free photoplethysmographic (PPG) device and method simultaneously for one or several persons in rest or moving. The device contains radiation sensitive sensor (20) with view zone (14) for obtaining electronic images (80) of one or more persons (40), distance detector (130), distance detector movement system (120), output block (100) and signal processing block (70). The method provides for registration of the photoplethysmographic signals, calculation of heart beat frequence and/or derivative parameters, evaluation of errors and their cutting out.
