Abstract:
A displacement measurement device and a measurement method are provided. A displacement measurement device includes a light projecting unit configured to generate a light beam; a sensor head configured to emit the light beam to a measurement target object and receive a light beam reflected at the measurement target surface within the emitted light beam; a storage unit configured to store a function using a distance between the sensor head and the measurement target surface as a variable; and a control unit configured to calculate the distance based on a wavelength of the light received by the sensor head. The control unit calculates a value of the function using a distance between the sensor head and the measurement target surface of the measurement target object as a value of the variable. The control unit corrects the calculated distance using the calculated value of the function.

Claim (Index 13):
A displacement measurement method comprising:\n a step of generating a light beam having a predetermined wavelength width; a step of emitting the light beam from a sensor head through a member by which wavelength dispersion occurs according to a refractive index so that a focus is formed on a measurement target surface of a measurement target object; a step of receiving a light beam that is reflected at the measurement target surface within the emitted light beam; a step of calculating a distance between the sensor head and the measurement target surface based on a wavelength of the received light beam; a step of calculating a value of a function by serving the calculated distance as a value of a variable in the function using the distance as the variable; and a step of correcting the calculated distance using the calculated value of the function.
