Title:
Tilted grid
Document Type and Number:
Japanese Patent JP6316889
Kind Code:
B2
Abstract:
The present invention relates to phase-contrast imaging which visualizes the phase information of coherent radiation passing a scanned object. Focused gratings are used which reduce the creation of trapezoid profile in a projection with a particular angle to the optical axis. A laser supported method is used in combination with a dedicating etching process for creating such focused grating structures.
