Abstract: A parking assist apparatus includes: a setting unit that sets, within a captured image in which objects surrounding a moving vehicle have been imaged, a first search area for searching for a pair of partition lines disposed between parking spaces that are adjacent to each other; and a detecting unit that searches the first search area to detect a first partition line out of the pair of partition lines. When the detecting unit detects the first partition line, the setting unit sets a second search area for searching for a second partition line out of the pair of partition lines on the basis of the first partition line.

Abstract: An assistance apparatus includes: an imaging unit that captures an image of a surrounding of a vehicle to generate a captured image; and a processing unit that corrects deviation of a correction target based on a preset reference value and a position of a vanishing point, a vanishing line, or a horizontal line specified in the captured image to assist driving of the vehicle.

Abstract: The stimulated Raman scattering detection apparatus includes first and second light pulse generators (1, 2) respectively generating first and second light pulses with first and second pulse periods, an optical system combining the first and second light pulses and focusing the combined light pulses onto a sample, and a detector (10) detecting the second light pulses intensity-modulated by stimulated Raman scattering generated by focusing of the combined light pulses onto the sample. The second light pulse generator divides each raw light pulse emitted with the second pulse period into two light pulses, delays one of the two light pulse with respect to the other thereof and combines the one light pulse divided from one raw light pulse and delayed, with the other light pulse divided from another raw light pulse emitted after the one raw light pulse, to generate the second light pulse.

Abstract: The Raman scattering measuring apparatus includes a first light generator to produce a first light, a second light generator to produce a second light having a frequency different from that of the first light, an optical system to focus the first and second lights to a sample, and a detector to detect the first or second light intensity-modulated by Raman scattering. The first light generator includes a wavelength extractor that performs a wavelength filtering to extract light of an extraction wavelength from light in a wavelength range including the extraction wavelength and an amplification of the light extracted by the wavelength filtering. The wavelength extractor performs a first filtering on an entering light, a first amplification on the light extracted by the first filtering, a second filtering on the light amplified by the first amplification and a second amplification on the light extracted by the second filtering.
