expanding combとは 意味・読み方・使い方

When a distance from a body of an interferometer to an object 110 or displacement is interferometrically measured by using laser beams of a plurality of wavelengths, obtaining interference measurement values that are measured at respective wavelengths, and expanding a measurement range by a synthetic wavelength that is equivalently longer than the wavelengths of the laser beams from combinations of the respective wavelengths, the wavelengths of the plurality of laser beams are measured by using an optical comb 104.例文帳に追加

複数の波長のレーザ光により、各波長で測定される干渉測定値を得て、各波長の組み合わせからレーザ光の波長よりも等価的に長い合成波長で測定レンジを拡大して、干渉計本体から対象物１１０までの距離または変位を干渉測定する際に、複数のレーザ光の波長を、光コム１０４を用いて測定する。 - 特許庁
