Use of a digital micromirror array as a configurable mask in optical astronomy

Creator:

Gilliam, Shawn

Abstract:

High resolution images of a dim companion in a binary star system can be obtained using a Digital Micromirror Array (DMA) as an optical mask. Imaging can be problematic because the intense light from the main star can saturate the detector and leave the companion unnoticed. Placement of the DMA...

Determining readability by computer analysis using the Fourier transform to calculate the spatial frequencies of words

Creator:

Piepmeier, Karen Swanson

Abstract:

The black and white pattern formed when an individual word is printed on a page was analyzed by the Fourier transform. The Fourier transform produces a sequence of sinusodial functions, usually called spatial frequencies, whose amplitudes depend upon the particular pattern analyzed. These amplitudes were examined to determine if the...
