The fundus photographing apparatus of the present invention includes an illumination light source that generates illumination light flux for illuminating a fundus (of a subject eye), a scanning optical system that converts the illumination light flux from the illumination light source unit into spot light to scan the fundus in two-dimensional directions of a horizontal direction and a vertical direction by the spot light, a light receiver that receives reflected light from each portion of the fundus illuminated by the spot light, and a fundus image acquiring unit that acquires a fundus image based on a signal from the light receiver, wherein the scanning optical system is provided with a scanner including a reflection mirror plate that rotates about orthogonal two axes to simultaneously deflect the spot light in the vertical direction and the horizontal direction for scanning.

Fundus photographing apparatus

An MEMS-scanning mirror device includes an electrostatic comb actuator, in which a mirror surface is formed below a top surface (TOPS) of the mirror device. In a method for manufacturing the MEMS-scanning mirror device having the electrostatic comb actuator, a mirror surface (BS) of a mirror plate (B) is formed by removing an insulating layer (I) thereon.

MEMS-scanning mirror device and method for manufacturing the same

It is made possible to improve the variations in the 'generated force (load)&#x2014;deflection characteristics'. A deformable mirror device includes: a substrate; a plurality of electrodes provided on the substrate; a spacer disposed on the substrate; a support member disposed above the spacer and having an opening passing through from a first face of the support member facing to the substrate to a second face of the support member facing opposite from the first face; a first insulation film provided on the first face of the support member; a second insulation film provided on the second face of the support member; and a deformable electrode film disposed so as to be opposed to the electrodes at a spacing, formed so as to cover the opening, and supported by the support member with sandwiching the first insulation film. The electrode film includes a reflection portion on a face opposite from the electrodes, and the support member is disposed on the substrate with sandwiching the electrode film, the first insulation film and the spacer.
