| 20080316561 | OPTICAL SCAN DEVICE, OPTICAL SCAN TYPE MICROSCOPE, OBSERVATION METHOD, CONTROL DEVICE, AND CONTROL PROGRAM - It is an object to realize smooth switching between free scanning and high speed scanning in a light scanning apparatus and a light scanning microscope. To attain the object, a light scanning apparatus includes at least three mirror scanners disposed at predetermined positions of a light path for light scanning, and a light path switching unit switching the light path between a light path in which a highest-speed mirror scanner among the mirror scanners is valid and a light path in which the highest-speed mirror scanner is invalid. Therefore, the switching between a free scanning mode and a high speed scanning mode is performed by the driving of the light switching unit and involves no movement of galvanometer scanners. In addition, since the resonant galvanometer scanner is invalid during the free scanning mode, it is possible to make the resonant galvanometer scanner on standby. | 12-25-2008 |

The holder holds the reflection mirror in a state in which the reflection mirror is forcibly bent in a first direction. The pushing unit pushes the reflection mirror held by the holder to bend the reflection mirror in a second direction opposite the first direction. The curvature correction device corrects the curvature of the main scanning line by adjusting an amount at which the pushing unit pushes the reflection mirror. The holder has a stiffness larger than the reflection mirror. | 01-08-2009 |

| 20080273231 | Optical Scan Engine Using Rotating Mirror Sectors - An optical scan engine includes a rotatable component, for example a disk or drum. The rotatable component includes a plurality of scan sectors that are arranged around the rotation axis and that lie substantially in a plane of rotation. Each scan sector includes a pair of reflective surfaces that typically are radially-facing. The incident optical beam typically propagates along a radial direction (e.g., towards the rotation axis) and each pair of reflective surfaces deflects the incident optical beam by approximately 180 degrees as that pair rotates through the incident optical beam. The deflected optical beam has a virtual image located on the rotation axis. As a result, the real image of the deflected optical beam rotates around the rotation axis at the same angular velocity as the scan sectors. Different scan sectors can be designed to yield diffeent deflections in the axial direction. The addition of a third reflective surface to each scan sector can be used to generate image points that are fixed in space as the scan sector rotates. | 11-06-2008 |
