While on the Gnotero<\/a> page (a Python app for accessing refs from Zotero<\/a>, a Firefox plugin-based citation manager, in case you’re wondering), I noticed that the same group has an Online Gabor Patch Generator<\/a>. Cool. Thanks, guys. But who uses this? Are there researchers who are savvy enough to put Gabor patches to use, but not savvy enough to bang out the 2-line MATLAB code for generating one*? Anyways, it also reminded me of some online calculators I came across a while ago. And on the topic of calculators, converting between light units can be annoying because light is measured in different ways. Some papers report total flux, others make point measurements… some normalize to the sensitivity of the eye (e.g., lux, lumen)… some calculate in terms of solid angle (radiant intensity)… etc. Here is a collection of calculators<\/a> that is not comprehensive, but certainly helpful for converting.<\/p>\n *In case you’re curious, this is the two-line MATLAB code that generates a Gabor patch.<\/p>\n \n While on the Gnotero<\/a> page (a Python app for accessing refs from Zotero<\/a>, a Firefox plugin-based citation manager, in case you’re wondering), I…<\/p>\n

\nThere’s more at the same site. I appreciate these tools being around, but when do they get used? When I’m designing an optical system, I’m plotting a family of curves, modeling, and things like that. Not just plugging-and-chugging through one equation. By contrast, I thought this one was kind of fun: Excitations per molecule for 2p calculator<\/a><\/p>\n\r\n[xx,yy] = meshgrid(-halfSize:halfSize, -halfSize:halfSize);\r\npatch = imrotate(exp(-((xx\/gaussEnv).^2)-((yy\/gaussEnv).^2)) .* sin((2*pi*spatialFreq).*xx),angle,'crop');\r\n<\/font><\/pre>\n","protected":false},"excerpt":{"rendered":"
