Abstract :
An instrument which noninvasively and accurately measures the ocular pulse is described. To acquire this signal, a fiber Fizeau interferometer operating at a wavelength of 632 nm is used. A unique dithering and signal processing scheme allows standard FM demodulation techniques to recover the ocular pulse signal from the interference pattern. A detailed description of this data acquisition method is presented along with the results of test measurements made on a model eye
