Abstract: Such a measuring scale is used in a position-measuring device in order to measure the relative position of two machine parts of a machine tool; the measuring scale is connected to one machine part and scanned by a scanner unit connected to the other machine part. The measuring scale consists of a graduation carrier (1) made of glass with a graduation (2), which carrier is non-positively connected to a U-shaped base (3) made of steel by means of an electrodeposited intermediate layer (10). Since the U-shaped base (3) has a larger areal moment of inertia than the graduation carrier (1), the resulting coefficient of thermal expansion of this measuring scale is equal to the coefficient of thermal expansion of the base (3) made of steel. Since the measuring scale is connected to the machine part of steel, the identical thermal changes in length of the measuring scale and the machine part mean that no thermally induced measurement inaccuracies occur. …<IMAGE>…

Abstract: A novel, high-speed spatial light modulator utilizing electron trapping materials. The electron trapping material is exposed to a pattern of modulating radiation, resulting in the excitation of electrons in the material at spatial locations corresponding to the pattern. When the light to be modulated (ordinarily coherent light) is simultaneously or subsequently passed through the material, it is absorbed in areas of the material where electrons have been excited. The unabsorbed modulated light passes through the electron trapping material, producing a negative image of the pattern of modulating radiation. The electron trapping material also emits an image of incoherent visible light as the released electrons fall back to the ground state. This visible image can be filtered out if the device is only being used for modulating coherent light. Conversely, the device can be utilized by detecting only the incoherent visible emission from the electron trapping material, which constitutes a multi­plicative product image of the electron exciting and electron releasing light incident on the electron trapping material.
