Patent SE-8104772-L (SE)
Inventor: ERICKSON K E
IPC: G01B11/02
Filed: 1981-08-10
Abstract: An electro-optical measuring system in a photogrammetric comparator or stereocompiler comprises a visible light transparent phase grating which is carried upon a surface of the photo support plate of the device. The grating is formed as a composite layer of  lambda /4 films of at least two dielectric materials of different refractive index which are deposited on the support in such a manner as to yield parallel bands in which the two film materials are in alternating sequence from band to band. As a result of this structure which ensures a constant physical and optical thickness with respect to transmitted imaging light over the whole granting pattern, image-degrading diffraction of the transmitted visible light is avoided, yet the grating pattern provides interfering diffraction in reflection which may be utilized in a precise displacement measuring system.

Abstract: The high-voltage direct-voltage source is composed of a bank of high-voltage capacitors and a charging circuit for charging the capacitors. A monitoring unit is connected in parallel with at least one of the high-voltage capacitors. After a predetermined limit value of the charging voltage has been exceeded, this monitoring unit emits a signal to a control device of the charging circuit preventing the further charging of the bank. The input of the monitoring unit is formed by a resistive voltage divider comprising a high-voltage-side and a low-voltage-side resistor. A high-voltage direct-voltage source is to be created in which a dielectric overloading of the high-voltage capacitors can be avoided in a simple manner which is insensitive to electric disturbances. This is achieved by the fact that the high-voltage-side resistor of the resistive voltage divider consists at least partially of non-linear voltage-dependent resistance material. Such a high-voltage direct-voltage source can be used, for example, in high-voltage direct-voltage transmission systems or in circuits for the synthetic testing of high-voltage circuit breakers.
