A simple system for displaying alphanumeric characters on an oscilloscope using an AIM-65 microcomputer

A simple system for displaying alphanumeric characters on an oscilloscope screen is described. It may be useful for those applications in which only a few chaxacters should be shown, but within small time limitations. The system, using an AIM-65 microcomputer, is capable of exposure durations below 100 microsec/character. Possibilities of speeding up the system and designing characters are indicated.     

The tilted Hermann grid illusion: 'illusory spots' versus 'phantom bands'

The Hermann grid illusion became a cause célèbre, when it was reported that small figural changes from straight to curved bars abolish the dark illusory spots. We demonstrate that this is not an all-or-none effect; rather, the visual system tolerates some tilt/curviness. We transformed straight and curved Hermann grids to rhombic Motokawa grids by gradually tilting the horizontal bars. Initially, we observed only dark illusory spots, then dark spots combined with phantom bands traversing the rhomb along the minor axis, and finally dark phantom bands only. This shows that two kinds of illusions can coexist in the same grid pattern.
