The mirror platform may be coupled to the coil frame at connection points generally disposed along the axis in order to reduce deflection of the mirror platform to reduce stress on the mirror in order to maintain the relative flatness of the mirror surface. Furthermore, the mirror platform may include flexible members disposed near an edge of the mirror platform generally along the axis to isolate the mirror platform and the mirror from warping of the coil frame and twist of the suspension arms to further maintain the relative flatness of the mirror.Type: ApplicationFiled: April 26, 2007Publication date: October 30, 2008Inventors: Dean R. Brown, Wyatt O. Davis, Jason B. Tauscher, David R. Bowman

Publication number: 20080266633Abstract: An optical scanning device includes a light source configured to emit light beams, a deflector to deflect the light beams emitted from the light source, a first optical assembly which is positioned upon a light path of the light beams traveling from the light source to the deflector and which forms an image with the light beams emitted from the light source in a sub scanning direction in a vicinity of the deflector, and a second optical assembly to form the image upon a surface to be scanned with the light beams deflected by the deflector. A principal ray of two of the light beams incident to the first optical assembly, which are located at each respective terminus in the sub scanning direction, are set so as to advance so as either to remain mutually parallel to or converge with one another after passing through the first optical assembly.Type: ApplicationFiled: April 22, 2008Publication date: October 30, 2008Inventors: Makoto HIRAKAWA, Yoshinori HAYASHI, Daisuke ICHII

Publication number: 20080266635Abstract: An optical apparatus uses a variable-optical-characteristic optical element whereby focusing, zooming or the like can be effected without moving a lens or the like and the whole optical apparatus can be arranged in a lightweight structure. The user wears a power transmitting unit 303 by hanging it from his/her neck, for example. The power transmitting unit 303 may be put in a clothes pocket or the like. The power transmitting unit 303 may be placed somewhere around the user. In the power transmitting unit 303, a transmitting circuit 305 is driven by a power supply 304 to send an electromagnetic wave from a transmitting antenna 306 toward variable-focus eyeglasses 302. The variable-focus eyeglasses 302 have a receiving antenna 307 provided on eyeglass frames 308 to receive the electromagnetic wave sent from the power transmitting unit 303. The received electromagnetic wave is, for example, boosted in voltage and rectified to drive the variable-focus lenses.Type: ApplicationFiled: June 26, 2008Publication date: October 30, 2008Applicant: OLYMPUS CORPORATIONInventors: Kimihiko NISHIOKA, Miyuki Murakami
