LIGHT SOURCE ADJUSTMENT UNIT, OPTICAL MEASUREMENT DEVICE, SUBJECT INFORMATION OBTAINING SYSTEM, AND WAVELENGTH ADJUSTMENT PROGRAM |
摘要 |
An optical measurement device includes a light source unit including a first laser light source configured to emit a laser beam having a first wavelength and a second laser light source configured to emit a laser beam having a second wavelength, a measurement wave number setting unit, and a light source adjustment unit configured to adjust at least one of the first wavelength and the second wavelength such that a difference between or a sum of a first wave number corresponding to the first wavelength and a second wave number corresponding to the second wavelength matches a measurement wave number set through the measurement wave number setting unit. |
