Abstract

Two slit and bar grids and optical fibers for lighting and reading are specially conceived to resist at high temperature (some hundreds of degrees Celsius) and constitute a fully optical moire setup, allowing measurement of displacement with a sensitivity of 0.25 micrometers . Automatic compensation of temperature is possible.
