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.<>

眼脉冲的干涉测量

介绍了一种无创准确测量眼脉搏的仪器。为了获取该信号，使用了波长为632 nm的光纤菲索干涉仪。独特的抖动和信号处理方案允许标准调频解调技术从干扰模式中恢复眼脉冲信号。详细介绍了这种数据采集方法，并给出了在模型眼上进行的测试测量结果。
