  • Imaging lens
    Patent number: 6639738
    Abstract: In an imaging lens made of three lens sheets, the second and third lenses from the object side are shaped substantially similar to each other, thereby reducing the manufacturing cost while improving resolution. The first lens L1 is a biconcave lens having a surface with a stronger curvature directed onto the object side. Each of the second lens L2 and third lens L3 is a biconvex lens having a surface with a stronger curvature directed onto the imaging surface side, while the second lens L2 and third lens L3 have the same form. As the second lens L2 and third lens L3 have the same form, the cost of manufacturing the imaging lens can be reduced, though being constituted by three sheets of lenses.

  • Electronic endoscope apparatus provided with AC lighting light source
    Patent number: 6635012
    Abstract: In an apparatus using an AC lighting lamp including a reflector and a condensing lens as a condensing unit and using a CCD to pick up an image of a subject irradiated with a light from the lamp, an entrance facet of a light guide is arranged between two condensing points G1 and G2 and at a position that is not close to either of the condensing points, particularly at an intermediate position therebetween so that lights from a bright spot g1 or g2 at a tip of a first or second electrode, respectively, of the lamp are condensed at the corresponding condensing point by the condensing unit. Thereby, although an amount of emission slightly decreases compared to the case where the entrance facet is arranged on the basis of the bright spot, emission with a reduced variation in luminance is obtained to enable photographing with a substantially uniform amount of exposure, while preventing possible flickers.

  • Fringe analysis method and apparatus using Fourier transform
    Patent number: 6621579
    Abstract: In a fringe analysis method using Fourier transform, fringe image data is determined in a state where a wavefront from an object and a wavefront from a reference are relatively inclined with respect to each other by a minute amount, and a carrier fringe occurring due to this inclination is superposed on a fringe occurring due to wavefront information of the object. The inclination is set such that the carrier frequency occurring due to the inclination is a predetermined multiple of the basic frequency determined by the wavefront information of the object and observing means.
