The SPGD algorithm shows great potential for aberration correction and improved run-time performance compared to our previous Resilient backpropagation (Rprop) algorithm when correcting for complex wavefront distortions. The fast computational aberration correction suggests that after further optimization our method can be integrated for future applications in real-time clinical imaging.Blackbody cavity reflectivity is normally measured using an integrating sphere to collect hemispherical reflected radiation from a blackbody opening when illuminated by a directional light source. The challenge of taking this method without an integrating sphere arises for blackbody cavity emissivity measurement in satellites due to space constraints. The ratio of hemispherical-given solid angle reflections is proposed to calculate the total reflected power from a blackbody cavity by multiplying a measurable reflected power in a given solid angle. The ratio is obtained by simulating the distribution relationship between the total hemispherical reflected light power and the reflected light power in the given solid angle under different coating emissivity. The emissivity measurement results are consistent with radiometric method measurements and simulation results, with an uncertainty of 0.0005.We study an analyzer grating based on a scintillation light blocker for a Talbot-Lau grating interferometer. This is an alternative way to analyze the Talbot self-image without the need for an often difficult to fabricate absorption grating for the incident radiation. The feasibility of this approach using a neutron beam has been evaluated and experiments have been conducted at the cold neutron imaging facility of the NIST center for Neutron Research.
