Optical Illusions
Illusions Optical illusions based on movement can be constructed in a variety of ways. Here we explore spinning disks and color wheels using simple patterns that create some spectacular optical illusions. The Java applets listed below contain a combination of different patter...
Now Just a Blinkin' Picosecond!
IBM Corporation's Almaden Research Center in San Jose, CA, have used ultrafast laser pulses to build ultrafast data-storage devices, achieving switching down to 100ps -- results that are almost ten times faster than currently available "speed limits". Left: Dr. Steve Paley (NASA/Mar...

reflectance properties. The unique spectral properties of a land cover class are derived from a number of factors, including canopy geometry, leaf densities, colors, optical properties and moisture content, shadows, transpiration rates, and the properties of nonvegetated areas. Defined by the wavelength bands collected for the image analysis, these attributes are known as the class spectral signature. Classification of land cover types using spectral reflectance properties requires the use of a computer to handle the

PREPARATION Students will benefit from a basic understanding of remote- sensing technology as presented in the “Reflections on Earth” teaching poster available from the Smithsonian’s National Air and Space Museum and web page. Divide the students into groups. Choose the group size so that there is one satellite <span class="highlight">image</span> <span class="highlight">for</span> each group, or make additional <span class="highlight">color</span> copies of the <span class="highlight">image</span>.

Growing Computers in Space? Novel Organic and Polymeric Materials for Optical Devices
photonics are non-linear optical (NLO) materials, which means that they interact with light in such a way that the light changes the properties of the material, which, in turn, changes the properties of the light. This can give rise to a number of interesting effects such as frequency convers...
