摘要
Blazing of real time holographic fringes employs an interferometer with a focal plane array (FPA) to receive interference fringes. An FPA frame is read into a fringe processor. For each row, minima are identified and a pixel value is saved and its position in the row recorded. The minima determination is repeated for each column in the row until all pixels in the row have been recorded. A blazed fringe for the single row is then created. The blazed fringe row is then transferred to a spatial light modulator (SLM). The minima determination and fringe blazing processes are repeated until all rows in the FPA array are read and transferred to the SLM. The next FPA frame is then read into the fringe processor.
