Patent number: 7710658Abstract: Zoom lens systems and methods for imaging incoming rays over a range of ray angles are disclosed. The incoming rays are characterized by at least phase. The zoom lens system includes an optical axis and is characterized by a plurality of modulation transfer functions (MTFs) corresponding at least to the range of ray angles. The zoom lens system includes an optical group disposed along the optical axis, including at least one variable optical element that has a variable focal length selectable between at least two distinct focal length values. The optical group also includes a wavefront coding element. The wavefront coding element alters at least the phase of the incoming rays, such that the plurality of MTFs corresponding to the range of ray angles, for each one of the two distinct focal length values, are less sensitive to misfocus-like aberrations than a corresponding system without the wavefront coding element.Type: GrantFiled: March 6, 2007Date of Patent: May 4, 2010Assignee: OmniVision CDM Optics, Inc.Inventors: Edward Raymond Dowski, Jr., Satoru Tachihara, Robert H.

Publication number: 20020118450Abstract: The optical system of the microscope includes a close-up optical system that faces an object, a pair of imaging optical systems that take object light rays passing through regions of the close-up optical system, and an illuminating optical system that guides illumination light emitted from a light source to illuminate the object. Each lens included in the close-up optical system has a semicircular shape in which one side is cut out. The close-up optical system is held in a first lens barrel, and the illuminating optical system is held in a second lens barrel. The second lens barrel is arranged in the cutout space of the close-up optical system inside the first lens barrel. A light shielding member is attached to the second lens barrel to prevent a leak of the illumination light through grooves formed on the second lens barrel.Type: ApplicationFiled: February 19, 2002Publication date: August 29, 2002Inventors: Eiichi Ito, Daisuke Koreeda, Satoru Tachihara

Patent number: 5798851Abstract: An optical scanner including a light source which is turned ON and OFF in accordance with drawing data. A hologram deflector, made of a rotatable planar hologram disc, provided with a plurality of hologram facets through which light emitted from the light source passes, is rotated to scan an image surface with light emitted from the light source. An optical detector detects light passing in a scanning direction through at least a first reference point, for the commencement of the scanning, and a second reference point, for the completion of the scanning. A scanning time detector detects a scanning time period in which the light deflected by each hologram facet of the hologram disc, passes the first reference point and reaches the second reference point. Finally, a frequency varying device varies the frequency of the light source for each hologram facet in accordance with a unique scanning time period directed by the scanning time detector for each hologram facet.Type: GrantFiled: April 22, 1997Date of Patent: August 25, 1998Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Satoru Tachihara, Ryota Ogawa, Katsuhiro Yoshino
