  • Patent number: 9612449
    Abstract: An axially symmetric polarization conversion element that converts incident light into an axially symmetric polarized beam includes a reflection section having a shape obtained by rotating the cross section of a Fresnel rhomb wave plate along the direction of an optical axis around an axis that is parallel to the optical axis. The axially symmetric polarization conversion element converts the incident light into an axially symmetric polarized beam by utilizing two Fresnel reflections by the reflection section.

  • Patent number: 9282887
    Abstract: Provided is a three-dimensional retina image generator that can detect, in a precise manner, the scanning position displacement during scanning of the retina with a simple configuration and, as a result, and can obtain a high-quality retinal image with a reduced influence of speckle noise therein. In order to detect the movement of retina R, the three-dimensional retina image generator has: second light source unit 210 that outputs a line beam to be imaged on retina R; positional displacement detector 220 that detects the line beam reflected from retina R and that detects the “displacement” of the scanning position during scanning of retina R; and dichroic mirror 230 that causes the line beam to propagate along the same light path as that of the object light scanning beam in inspection unit 140.

  • Patent number: 9039175
    Abstract: An optical coherence eye-fundus tomography device has a high resolution and a good operability, as well as be miniaturized and be produced at a low cost. The optical coherence eye-fundus tomography device includes: a light source unit which emits a source light beam; a reference-light unit which reflects a reference light beam; an inspection unit which illuminates an object with an object scanning light beam, reflected the object scanning light beam; and a detection unit which obtains a tomographic image of the object on the basis of the interference light beam produced by interfering the reflected reference light beam with the reflected object light beam. For example, the light source unit emits the outgoing light beam that has a depth of focus of not less than 300 ?m, and resolution that is 6 ?m×6 ?m or higher in a planar direction perpendicular to a traveling direction of the outgoing light beam.

  • Patent number: 8825257
    Abstract: An autonomous navigation method is a method of causing a mobile body (100) to autonomously navigate while comparing environmental magnetism data obtained in advance by measuring magnetism generated along a navigation path on which the mobile body (100) navigates and measured magnetism detected by actually measuring the magnetism generated along the navigation path when the mobile body (100) navigates along the navigation path. The method includes a step (a) of detecting first measured magnetism and second measured magnetism in different positions on the mobile body (100) and a step (b) of causing the mobile body (100) to autonomously navigate on the basis of the second measured magnetism detected by a magnetism sensor (103), which is not affected by unexpected magnetism (G) not included in the environmental magnetism data, and the environmental magnetism data.
