    摘要： The present invention includes: a rolled filter stretched between first and second winding shafts and, unused part of the filter being wound around the second winding shaft; a brush provided between the first and the second winding shafts so as to come into contact with a surface of the filter; a feeding mechanism for driving the first and the second winding shafts to take up or rewind the filter; and a feeding control unit for controlling the feeding mechanism. When activating a renewing operation for feeding unused part of the filter from the second winding shaft, the feeding control unit controls the feeding mechanism such that once the filter is taken up by the first winding shaft by an take-up amount La, the filter is rewound by the second winding shaft by a rewind amount Lb, and La and Lb satisfy a relationship La≧Lb. Without increasing the amount of the filter or the size of the device itself, the present invention can deliver adequate performance even in a dusty environment by a small number of filter renewing operations.

    摘要： The optical tomographic image acquisition apparatus is based on FD-OCT. A detection unit 50A which detects interference light includes a lens 51, a reflection type diffraction grating 52A, a deflection unit 53, a lens 54), and a light receiving unit 55. The interference light collimated by the lens 51 is divided by the reflection type diffraction grating 52A. Light of each wavelength is output in a different direction according to the wavelength, deflected by the deflection unit 53, and focused on a light receiving surface of the light receiving unit 55 by the lens 54. The optical tomographic image of the object is acquired based on a correspondence relationship between a light radiation position for the object and a deflection angle by the deflection unit 53 and on optical power distribution detected by the light receiving unit 55.
