OPTICAL IMAGE MEASUREMENT INSTRUMENT AND PROGRAM FOR CONTROLLING THE SAME

摘要

An optical image measurement instrument capable of rapidly acquiring accurate images of a region of interest in an object to be measured. A fundus examination device (1) is an optical image measurement instrument which detects interference light LC derived by dividing a low-coherence light LO into a signal light LS and a reference light LR, then by superimposing the signal light LS passing through a fundus Ef and the reference light LR passing through a reference mirror (174), and forms the OCT image of the fundus Ef in accordance with such a detection result. The fundus examination device (1) has a scanner unit (141) for scanning the fundus Ef with the signal light LS, and a control section (210) for controlling the scanner unit (141) to perform scanning with the signal light LS while changing the scanning intervals in performing a series of scanning with the signal light LS. This allows accurate images to be acquired at small scanning intervals for a region of interest, while allowing the scanning time to be shortened at large intervals for the rest of regions. Therefore, the fundus examination device (1) is capable of rapidly acquiring accurate images of a region of interest in the fundus Ef.
