摘要： Such an optical image measurement device is provided that is capable of acquiring a clear image even when the intensity of an interference light is low. A fundus oculi observation device 1 is configured to superimpose a signal light LS propagated through a fundus oculi Ef and a reference light LR propagated through a reference mirror 174 to generate an interference light LC, detect the interference light LC, and form an image of the fundus oculi Ef. The device 1 determines whether the intensity of a detection signal of the interference light LC is equal to or more than a predetermined threshold and, when determines that the intensity is less than the predetermined threshold, controls to increase the intensity of the detection signal of the interference light LC. The device 1 forms an image of the fundus oculi Ef based on the detection signal with the increased intensity.

摘要： To provide an ophthalmologic imaging apparatus that enables even those having no or little knowledge and experience about using the apparatus to easily perform a test. An ophthalmologic imaging apparatus of an embodiment includes: an optical system configured to divide light from a light source into measurement light and reference light, cause the measurement light returning from a subject's eye to interfere with the reference light, and detect interference light resulting therefrom; a processor configured to process a detection result of the interference light obtained by the optical system to generate test data indicating the state of the subject's eye; an output unit configured to output the test data generated by the processor; an interface used to make the setting of a predetermined item related to the optical system and the processor; a storage configured to store setting information indicating the content of the setting made through the interface; and a controller configured to control the optical system and the processor based on the content of the setting indicated by the setting information in each of a plurality of tests performed until the setting information is changed or deleted.

摘要： An optical image measuring instrument capable of shorting the measurement time. A flash is outputted from a xenon lamp (2) and converted into a wide-band light by means of an optical filter (2A). The flash is converted into a linearly polarized light by means of a polarizing plate (3). The linearly polarized light is divided into a signal light (S) and a reference light (R) by means of a semitransparent mirror (6). The reference light (R) is converted into a circularly polarized light by means of a wavelength plate (7). The signal light (S) and the reference light (R) are combined by means of a semitransparent mirror (6) to produce an interference light (L). A CCD (23) detects the interference light having the same characteristic as the interference light (L). The interference light (L) is separated into an S-polarized component (L1) and a P-polarized component (L2) by means of a polarized beam splitter (11). These components are detected by means of CCDs (21, 22). A computer (30) creates an image of an object (O) to be measured from the detection signals from the CCds (21, 22, 23). Wit such an optical image measuring instrument (1), since two polarized components (L1, L2) of the interference light (L) can be simultaneously obtained, the measurement time can be shortened.
