Title: Waveguide type wavelength conversion element
Inventor: OTA YOSHINORI
IPC: G02B6/12
Filed: 1990-08-17
Abstract: PURPOSE:To obtain second harmonic generating(SHG) output light free from a wavefront aberration by injecting a reference wave from one end of a channel optical waveguide and obtaining the second harmonic wave from the other end. CONSTITUTION:The output light of a semiconductor laser 4 is connected to one end face of the channel optical waveguide 3 as an incident reference wave. The reference wave generates SHG light through a secondary non-linear optical effect included in crystals in accordance with its advance. The SHG light converted from the reference wave is guided by the same channel optical waveguide 3 and radiated from the other end face of the waveguide 3. The waveguide SHG light radiated from the other end face of the waveguide 3 is converted into a circular collimate beam 6 by a circular lens 5. Thus, a stable waveguide type wavelength conversion element capable of removing a wavefront abberation from its SHG output light can be obtained.

Title: Camera equipped with focus detecting device
Inventor: AKASHI AKIRA
IPC: G02B7/34
Filed: 1988-08-31
Abstract: PURPOSE:To carry out focus detection with highly accurate selection by performing multiplication by weight in accordance with the length of the base lines of corresponding focus detecting systems when the contrast of the output of plural sensors is compared. CONSTITUTION:The defocus of an object image by an objective lens LNS is photoelectrically converted by vertical and horizontal sensors SNS which store electrostatic charge and extract the defocus by light quantity distribution. When sensors for a brightness monitor rise up to a prescribed value, a signal is generated. In response to this, the output signals of the sensors SNS are fetched successively in the prescribed address of an RAM by a microcomputer PRS through a driving circuit SDR. At this time, contrast images based on vertical and horizontal sensor images are multiplied by a weight coefficient C0>C1 respectively, and then compared with a prescribed amount previously set. When products are smaller than the prescribed amount, the images are in focus. Thus, by correcting the output of SNS pairs having difference in the length of the base lines in the vertical and the horizontal directions, a focus detecting operation can be performed with high accuracy.

Abstract: PURPOSE:To position a condensing lens with a high accuracy and prevent the condensing lens from floating above an etched hole by a method wherein an etching mask with a rectangular hole is formed on the upper surface of a light emitting part and the upper surface of the light emitting part is etched until the shape of the etched hole becomes square. CONSTITUTION:An etching mask 3 is so formed as to have a rectangular hole whose long side is parallel to the direction making right angles with a face (-10) and short side is parallel to the direction making right angles with a face (110). The hole part of the etching mask 3 is etched with etchant such as hydrochloric acid to form an etched hole 4. At that time, the etching time which is so predetermined as to make the shape of the hole 4 square while the hole is observed from the above is employed. Or, etching is carried out in the manufacturing process while the hole 4 is observed so as to make the shape of the hole 4 square. The latter method has an advantage that, even if the etching conditions are varied, the constant depth of the etched hole 4 can be obtained by keeping on etching until the shape of the hole 4 becomes square.

Title: Color image separation reader
Inventor: NISHIHARA HIROSHI
IPC: G02B5/18
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To attain color separation and image forming by a diffraction optical element by reflecting an incident light in a grating vector set in response to an incident position within an incident range of each color light and linearly forming a diffraction light on a photo sensor. SOLUTION: A color separation diffraction optical element (CSGL) 2 separates an incident light L1 into red, green, blue lights so as to be diffracted to have a spread of a degree on a face of an image forming correction diffraction optical element (ICG) 3. Then a linear light is emitted onto an image, a reflected light is diffracted and separated into three color lights by the CSGL 2 so as to reflect or transmits each color light collectively. The ICG 3 placed at a position up to a focus of each color light corresponding to each color light diffracts the incident light in a grating vector set depending on the incident position at an incident range of each color to form an image of the diffracted light linearly on a light sensor. Thus, the diffraction optical element can separate colors and form an image and the reader with high resolution can easily be manufactured at a low cost.
