Abstract
A biological information measuring technique with improved reliability is proposed. A method of measuring biological information using an optical element with a totally reflecting surface, which is to be brought into contact with an object to be observed, is provided. The method includes, after the optical element has been in contact with the object to be observed, acquiring an absorbance at the totally reflecting surface in a state where the optical element is not in contact with the object to be observed, and determining by an information processing apparatus whether the object to be observed needs to be cleaned, based on the absorbance.
Claims11
A method of measuring biological information using an optical element with a totally reflecting surface, which is to be brought into contact with an object to be observed, comprising:
- after the optical element has been in contact with the object to be observed, acquiring an absorbance at the totally reflecting surface in a state where the optical element is not in contact with the object to be observed;
- and
- determining by an information processing apparatus whether the object to be observed needs to be cleaned, based on the absorbance.
A method of measuring biological information using an optical element with a totally reflecting surface, which is to be brought into contact with an object to be observed, comprising:
- before the optical element comes into contact with the object to be observed, acquiring an absorbance at the totally reflecting surface at a first wavenumber;
- and
- determining by an information processing apparatus whether or not the optical element needs to be cleaned, based on the absorbance at the first wavenumber, the first wavenumber being in a range of 1700 cm−1 to 1800 cm−1 or 2800 cm−1 to 3000 cm−1.
(canceled)
A measuring system comprising:
- a measuring device having an optical element with a totally reflecting surface, a light source, and a photodetector configured to detect a light output from the light source, reflected by the totally reflecting surface, and output from the optical element;
- and
- an information processing apparatus configured to process a detection result of the photodetector,
- wherein the light source is configured to output light beams of different wavenumbers including a first wavenumber, the first wavenumber being in a range of 1700 cm−1 to 1800 cm−1 or 2800 cm−1 to 3000 cm−1, and
- wherein the information processing apparatus acquires an absorbance measured at the totally reflecting surface at the first wavenumber in a state where the optical element is not in contact with an object to be observed.
