20080265145 | Optical Element and Optical Measurement Device Using the Optical Element - Provided is an optical element in which a groove for a sample to make contact can be formed without machining or etching a material for an optical element, and in which the scattering of a light at the groove does not decrease the precision in an optical measurement. The optical element is formed with a light-emitting prism including a light-output face from which a light to be emitted to a sample is outputted, a light-receiving prism including a light-receiving face which receives the light returned from the sample, and a light intensity-reducing part provided between the light-emitting prism and the light-receiving prism. The light-emitting prism and the light-receiving prism are combined to form a recessed part for the sample to make contact, so that the light outputted from the light-output face travels straight in the sample in contact with the recessed part and enters the light-receiving face. | 10-30-2008 |

20100063369 | OPTICAL BIOLOGICAL INFORMATION MEASURING APPARATUS, OPTICAL BIOLOGICAL INFORMATION MEASURING METHOD, BIOLOGICAL INFORMATION DECISION APPARATUS, PROGRAM AND RECORDING MEDIUM - An optical biological information measuring apparatus includes a measuring surface to be placed on the surface of a living body, a mark display section which displays a mark at a region to be measured on the surface of the living body, a light-emitting section which irradiates the living body with light of a predetermined wavelength and a light-receiving section which receives light irradiated onto the living body and returned from the living body, and measures information on the living body based on the received light. The optical biological information measuring apparatus is capable of measuring biological information with improved alignment accuracy. | 03-11-2010 |
20130002930 | LIGHT-REDUCTION DEVICE AND IMAGING APPARATUS - A light reduction device for adjusting an amount of light reaching an imaging device includes: a light shielding plate in which light shielding parts are discretely formed for blocking the light, and a light transmission part is formed for transmitting the light; a first light reduction plate in which light reduction parts are discretely formed for reducing the amount of the light passing through, and a light transmission part is formed for transmitting the light; and a moving unit configured to move at least one of the light shielding plate and the first light reduction plate in a first direction which intersects with an incident direction of the light, in which the light shielding plate and the first light reduction plate overlap each other at least in part, when viewed from the incident direction of the light. | 01-03-2013 |
20130088767 | OPTICAL-PATH CONVERSION DEVICE AND IMAGING APPARATUS - An optical-path conversion device includes: a plate-shaped phase modulation mask in which a plurality of phase modulation parts are discretely formed for providing phase modulation to light passing through, and a first light-transmission part is formed for transmitting the light; and a plate-shaped light-shielding member in which a plurality of light-shielding parts are discretely formed for blocking the light, and a second light-transmission part is formed for transmitting the light, in which the phase modulation mask and the light-shielding member overlap each other at least in part, when viewed in an incident direction of the light, and at least one of the phase modulation mask and the light-shielding member is movable in an intersection direction which intersects with the incident direction. | 04-11-2013 |
