摘要： An optical image measuring device 1 splits low-coherence light L0 into signal light LS and reference light LR, and splits an optical path of the reference light LR into two optical paths having different optical path lengths to split the reference light LR into two reference lights LRa, LRb. Furthermore, the optical image measuring device 1 makes the reference lights LRa, LRb interfere with the signal light LS propagated through an eye E, generates an interference light LC reflecting a morphology in each of two depth positions (fundus oculi Ef and cornea Ec) of an eye E, and detects the interference light LC to generate a detection signal. Then, the optical image measuring device 1 forms a fundus oculi tomographic image and a cornea tomographic image based on the detection signals, and analyzes the tomographic images to obtain a distance between the cornea and retina of the eye E.
