Device and method for determining the energetic composition of electromagnetic waves

摘要

The present invention relates to a method and device for determining the energetic composition of electromagnetic waves. It is the object of the present invention to provide a method and device for X-ray spectroscopy that allows simultaneous detection of the individual energies at a comparatively higher resolution and/or across a comparatively wider energy range. According to the invention, at least one reflective zone plate (12) is used that comprises a multitude of predefined wavelength-selective regions (14) arranged next to one another, wherein the wavelength-selective regions (14) each include a multitude of reflecting arched portions (20), which extend exclusively and continuously across the respective wavelength-selective region (14).

主权项

1. A device for determining a spectrum of electromagnetic waves of a source, comprising:
at least one reflective zone plate and at least one position-resolving detector, wherein the reflective zone plate comprises a multitude of predefined wavelength-selective regions arranged next to one another and the position-resolving detector comprises a multitude of corresponding receiving sections, wherein the wavelength-selective regions each include a multitude of reflecting arched portions which exclusively extend across the respective wavelength-selective region, characterized in that the arched portions each form a part of an ellipse, wherein the arched portions extend along at least 10% of the circumference of the respective ellipse.
