Abstract: A multiplexing optical system includes a light source, a lens and a lens array. The light source includes a plurality of light emitting elements of surface emitting lasers. The lens is configured to change and condense optical paths of laser light beams emitted from the light emitting elements. The lens array includes a plurality of lens regions arrayed so as to correspond to respective optical paths of the laser light beams changed by the lens, and is configured to condense the laser light beams by the lens regions to form a multiplexed beam.

Abstract: A laser module includes: a photonic crystal surface-emitting laser element; a collimating lens array for producing a parallel optical beam; a condenser lens for condensing the optical beam; and an optical fiber which receives the optical beam on one end and transmits the optical beam to the outside. In the collimating lens array, an aperture portion corresponding to a collimating lens allows passage of the optical beam with an energy of not less than 94.0% and not more than 99.5% with respect to 100% of the energy of the optical beam incident on the collimating lens array.

Abstract: A refrigerator system capable of reducing decrease in the accuracy of detecting change in a storage state and reducing a communication load for transmitting images of the inside of a storeroom, which are taken at a plurality of viewpoints to the outside of a refrigerator is provided. To achieve this, the refrigerator system includes: a camera configured to take the images of the inside of the storeroom; a camera moving device configured to move the camera at least in the vertical direction; a communication device configured to transmit the images taken by the camera to the outside of a main body; and a change detecting device configured to detect change in a food-item storage state of each shelf based on the images taken by the camera. The camera takes images of each shelf at a first viewpoint and a second viewpoint. The change detecting device detects change in the food-item storage state of the shelf based on the image taken at the first viewpoint. The communication device transmits, for the shelf, change in the food-item storage state of which is detected, both images taken at the first viewpoint and the second viewpoint to the outside of the main body.

Abstract: The obstacle detection apparatus mainly includes an optical deflector, a first reflection mirror, a second reflection mirror, and a light receiver. The first reflection mirror is arranged to face the optical deflector. The second reflection mirror is arranged at one side of the first reflection mirror further from the optical deflector. The optical deflector scans a light beam conically about a first axis. The first reflection mirror and the second reflection mirror are driven to rotate about a second axis in synchronization with each other. The second axis is coaxial with the first axis.

Abstract: A distance measuring apparatus to measure a distance to an object includes: a plurality of light sources to emit a first light and a second light; a mirror; and a light receiving unit. When the mirror rotates about the first and third axes, an angle formed by an optical axis of the second light projected on the first plane and the second axis is larger than an angle formed by an optical axis of the first light projected on the first plane and the second axis, and an angle formed by the optical axis of the second light projected on the second plane and the second axis is larger than an angle formed by the optical axis of the first light projected on the second plane and the second axis.
