|1. (WO2017194832) AN ARTIFACT FOR DETERMINING RESOLUTION OF IMAGING BASED ON ELECTROMAGNETIC RADIATION AND/OR MECHANICAL WAVES|
|Applicants:||ÅBO AKADEMI (ÅBO AKADEMI UNIVERSITY)
|Title:||AN ARTIFACT FOR DETERMINING RESOLUTION OF IMAGING BASED ON ELECTROMAGNETIC RADIATION AND/OR MECHANICAL WAVES|
An artifact (101) for determining resolution of imaging based on electromagnetic radiation, mechanical waves, or both is presented. The artifact comprises a substrate (102) and layers (103, 104) on top of the substrate. The layers comprise organic material and are stacked on each other in a partially overlapping way so that an edge (107) of a first one of the layers is arranged to intersect with an edge (108) of a second one of the layers. The layers constitute a three-dimensional surface topography where a groove (111) defined by the edges of the first and second ones of the layers is tapering towards a point of intersection (112) between the edges. The resolution is a minimum width of the tapering groove which is revealed by the imaging so that a pre-determined criterion is fulfilled.
