Abstract
By measuring the optical pulse, it is possible to obtain important information on the condition of a patient´s cardiovascular system. A laser interferometer has been developed to gather this information noninvasively and without contacting the eye. A two-frequency laser is used, and the interference pattern yields the ocular pulse signal by standard FM demodulation techniques. The method, the theory that underlies it, and test results of the system are presented
