Multiple-beam interference fringes have been projected onto the retina to serve as a size reference for fundus photography. The absolute fringe spacing is determined by measurable parameters. The interference fringes are extremely narrow so that fringe maxima and fundus structures can be perceived equally well, and a high precision of measurement is achieved. The method has been applied to a model eye of varying ametropia (within +/- 7 diopters). The reproducibility of measurement is within 0.5%. In vivo measurements on human eyes demonstrate the clinical applicability.
多光束干涉条纹已投射到视网膜上，用作眼底摄影的尺寸参考。绝对条纹间距由可测量参数确定。干涉条纹极窄，因此条纹最大值和眼底结构能被同样清晰地感知，从而实现了高精度测量。该方法已应用于不同屈光不正（±7屈光度范围内）的模型眼。测量的重现性在0.5%以内。对人眼的活体测量证明了其临床适用性。
