SummaryWe demonstrate compact full-field soft X-ray transmission microscopy with sub 60-nm resolution operating at λ = 2.48 nm. The microscope is based on a 100-Hz regenerative liquid-nitrogen-jet laser-plasma source in combination with a condenser zone plate and a micro-zone plate objective for highresolution imaging onto a 2048 × 2048 pixel CCD detector. The sample holder is mounted in a helium atmosphere and allows imaging of both dry and wet specimens. The microscope design enables fast sample switching and the sample can be prealigned using a visible-light microscope. High-quality images can be acquired with exposure times of less than 5 min. We demonstrate the performance of the microscope using both dry and wet samples.

“…Due to its advantages, Siemens Stars are widely used in many fields that use imaging sensors such as examining holographic sensors (Stockmar, et al, 2013) or in the field of X-ray imaging (Hofsten, et al, 2007). An interesting application of this type of target is to study so-called.…”

ABSTRACT:The ground resolved distance (GRD) of an imaging sensor, i.e. the size of the smallest element distinguishable on acquired imagery, is one of the most important sensor quality assessment factors, as it is directly linked to the amount of information that can be derived from the end product. The paper is a review of a wide variety of calibration targets used for determining the spatial resolution of remote sensing sensors. The author provides a description of calibration targets used historically and then moves on to high-frequency targets used for high-resolution remote sensing imaging equipment. As analysis is made which of these types of targets are best suited for UAV sensors, taking into account parameters very specific to UAVs: frame size, small GSD values and low flight stability.

“…Before describing our derivation, we should mention that a similar problem has been solved for fluorescent microscopy (Agard et al, 1989) and for the 2D case in X-ray microscopy (Weiss et al, 2000a;von Hofsten et al, 2007). To the best of our knowledge, the only works that we have been able to find for the 3D case are those in which numerical modeling (instead of analytical derivation) is used (see Bertilson et al (2011)) or in Dey et al (2002), where some results are presented without derivation.…”
