Spiral phase
WebFeb 7, 2024 · The Spiral Software Development methodology is an effective, incremental, efficient and iterative approach to software development that consists of a conglomeration of Waterfall and Agile practices. It was first proposed in 1986 by Barry Boehm, a distinguished professor of computer science. WebThe spiral phase contrast method has interesting applications in optical microscopy and interferometry. In microscopy, a spiral phase contrast filter with an absorptive central point (blocking the zero-order Fourier component of the image wave) can be used for isotropic edge enhancement of both amplitude and phase samples.
