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.
Claims9
A displacement measurement system comprising:
- 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.
A displacement measurement system comprising:
- a sensor that is contactable with a measurement target object and includes a first light emitting particle layer in which first light emitting particles that emit light at a first wavelength by an excitation energy are distributed over at least a one-dimensional spread, a second light emitting particle layer in which second light emitting particles that emit light at a second wavelength different from the first wavelength by the excitation energy are distributed over the spread, and a second spacer layer that separates the first light emitting particle layer from the second light emitting particle layer in a direction intersecting the spread;
- an excitation energy source that causes the first light emitting particles and the second light emitting particles included in the sensor to emit light;
- a light receiver that receives light emitted from the sensor;
- and
- an image analyzer that measures a displacement of the measurement target object that is in contact with the sensor based on a wavelength distribution of the received light.
