Patents by Inventor Roelof Wijnaendts-Van-Resandt

Roelof Wijnaendts-Van-Resandt has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9052608
    Abstract: A method and apparatus for imaging a radiation-sensitive substrate, wherein a programmable template is projected onto the radiation-sensitive substrate using coherent radiation having a wavelength at which the substrate is radiation sensitive. An overall image of the programmable template having an image grid is displaced simultaneously by an acoustic-optical or electro-optical deflection unit such that multiple projections impinge on the substrate at different positions such that a fine partial grid is created in the image grid on the substrate.
    Type: Grant

  • Patent number: 7487069
    Abstract: A method for optically detecting the position of a moveable test object (10), especially a mirror or reflector, in which a measuring beam (6) produced by a light source (2) is reflected by the test object (10 and reaches a position-sensitive light detector (12) which carrier out a conversion into information corresponding to the position of the test object (10). The invention enables the position of mirrors, especially rotating mirrors, to be quickly measured optically using a simple optical construction. The measuring beam (6) is focused onto the light detector (12) by an optical system (8). A signal corresponding to the geometric center or the maximum (I0) of the intensity distribution of the focused measuring spot is determined based on the measured values obtained by the light detector (12).
