Abstract
A measuring system for measuring the position of an object comprises a laser (10), a laser interferometer (16), and a detector (24). A series of sensors for sensing environmental conditions are provided; the sensors may be attached to the object. The sensors transmit information back to a central control (46) via LED transmitter (54). The transmitter (54) is powered from a battery (56) which is in turn charged by transducing (with a solar cell) part of the power of the light beam (12) generated by the laser (10). The sensors may be temperature sensors, pressure sensors, humidity sensors, refractive index sensors, vibration sensors, or beam alignment sensors.
