Opt. 18, 4206-4209 (1979). doi: 10.1364/ao.18.0042060003-6935http://hdl.handle.net/10919/46881An incoherent optical processing technique for color coding the spatial frequency content of an input is described. Experimental results and comparison with the output of a coherent filtering system are discussed. Possible applications such as texture recognition in aerial imagery or radiography analysis are suggested.en-USIn CopyrightArticle - Refereedhttp://www.opticsinfobase.org/ao/abstract.cfm?URI=ao-18-24-4206https://doi.org/10.1364/ao.18.004206
