Abstract
Provided is a displacement measurement system including: a sensor that is contactable with a measurement target object and includes a first spacer that has at least a one-dimensional spread, and two or more types of light emitting particles that are distributed over the spread of the first spacer and emit light at different wavelengths by an excitation energy; an excitation energy source that causes the two or more types of light emitting particles included in the sensor to emit light; and a light receiver that receives light emitted from the sensor.
