Investigation of smooth wave fronts using SLM-based phase retrieval and a phase diffuser
Get PDFA phase retrieval technique using a spatial light modulator (SLM) and a phase
diffuser for a fast reconstruction of smooth wave fronts is demonstrated
experimentally. Diffuse illumination of a smooth test object with the aid of a
phase diffuser (maximum phase shift, Df = 0.85p) results in a significant
diversity in the intensity measurements which, in turn, is beneficial for a
non-stagnating iterative phase reconstruction. The use of the SLM enables
accurate and fast speckle intensity recording and active correction of
misalignments in the setup. The effectiveness of the technique is demonstrated
in the optical testing of lenses.Comment: The paper has been presented in 1st EOS Topical Meeting on Micro-and

Issues and options related to management of Silver Springs rhesus macaques
Get PDFManagement options for the Silver Springs free-ranging
rhesus macaque population range from removal to active
maintenance of the population in situ. Selection of a management
option is dependent upon which issues are perceived to be true
problems. Management options are presented along with their
effectiveness in dealing with issues previously described.(31 page document
