Patent number: 8121666Abstract: An image observation apparatus comprising an image display unit for displaying an observation image and a supporting mechanism for supporting the image display unit movably and adjustably in the directions of three, substantially perpendicular axes. Since the supporting mechanism of this image observation apparatus can move and adjust the image display unit in three orthogonal axial directions, an operator need not select a plurality of articulates for operating them when he/she wants to move the image display unit to a desired axial direction. Further, one of the three axes can be a rotational axis for turnably supporting the image display unit around the operator. According to this configuration, the image display unit can be independently moved and adjusted in three axial directions, while the observation angle of the observer with respect to the display face of the image display unit is kept constant.Type: GrantFiled: July 27, 2005Date of Patent: February 21, 2012Assignee: Olympus CorporationInventors: Satoshi Otsuka, Takashi Fukaya, Junichi Nozawa, Tomonori Ishikawa

Patent number: 7088504Abstract: Binocular luminous fluxes are formed by an objective lens and a pair of relay lenses and go through a splitting optical system, which allows an assistant to observe the same stereoscopic view as the surgeon by using an assistant's binocular eyepiece optical system at a location across from the surgeon via a splitting optical system. Part of at least one of the binocular luminous fluxes is incident on a pupil splitting optical system, forming a binocular luminous flux that has undergone pupil splitting, which allows stereoscopic observation by pupil splitting even when the assistant's binocular eyepiece optical system is rotated to the surgeon's side.Type: GrantFiled: December 11, 2003Date of Patent: August 8, 2006Assignee: Olympus CorporationInventors: Takashi Fukaya, Tomonori Ishikawa, Shunichiro Takahashi
