Optical device comprising a cantilever and method of fabrication and use thereof |
摘要 |
The present invention provides an optical device, comprising an optical fiber and a cantilever that is arranged on an end of the optical fiber; The cantilever may be an integral part of the optical fiber, and may have a length that is substantially equal to a diameter of the optical fiber. Measurement means for measuring a displacement of the cantilever are connected to an opposite end of the, optical fiber. A method of measuring a displacement using the optical device comprises the steps of:—arranging measurement means, comprising a light source, on an opposite end of the optical fiber;—using the light source to send a beam of light into the optical fiber;—measuring the interference of light that is reflected on the end op the optical fiber and light that is reflected on the cantilever; and determining the displacement of the cantilever relative to an intermediate position dependent on the measured interference.
