Modified slanted-edge method to measure the modulation transfer function of camera

Halogen-bonded charge-transfer co-crystal scintillators for high-resolution X-ray imaging

“…5d , right). 41 Besides, measured by the slanted edge method, 42,43 the actual spatial resolution was found to be 26.8 lp per mm at MTF = 0.2 ( Fig. 5e ), and details of the edge method are provided in the ESI.…”

Super‐Resolution Photothermal Imaging at the Microscale by Model‐Based Image Reconstruction

“…Aiming at quantifying the actual SR capabilities of the proposed approach and at demonstrating the possibility of performing SR thermography down to the microscale, the MTF and PSF of the imaging system have been experimentally characterized by the so‐called knife‐edge method. [ 28 ] The excitation laser beam has been focused at first to a 7 μm waist and SR thermal images have been acquired for varying scan pixel size and pixel dwell time across the interface of black matte tape on a glass coverslip (Methods section and Figure a). An optical transmitted‐light image of the sample has been acquired as reference ground‐truth frame and the normalized intensity profile, extracted orthogonally to the tape interface, has been superimposed to the corresponding profile (the edge spread function, ESF) from the reconstructed SR thermal images.…”
