OPTICAL POSITION MEASURING DEVICE USING OPTICAL-FIBER

Title:

OPTICAL POSITION MEASURING DEVICE USING OPTICAL-FIBER

Document Type and Number:

Japanese Patent JPS58190715

Kind Code:

A

Abstract:

An optical position-measuring sensor has a monolithic structure which includes at least two masses of photoluminescent material, which on excitation emit photoluminescent light with non-identical spectra. The at least two masses are supported in the sensor by a resilient part (e.g. a beam or diaphragm), the deflection of which determines the wavelength distribution of the luminescent light which is coupled into an optical wave conductor (e.g. a light fiber) terminating in the sensor.
