... The substepping technique is used for the Hubble Space Telescope (HST) imaging to cope with the problem of undersampling and to improve resolution. ... For the HST, undersampling means that the size of the pixel in a camera is larger than the critical value determined by the optics of the telescope, and aliasing takes place. ... Sampling is an operation to integrate a ( x ) within a pixel, and to assign the result to this pixel (Figure 1 A). ... Figure 1: Substepping ( N =2) and normal sampling. ...

This radar image of 2007 TU24 was obtained on January 28, 2008, about 12 hours before the asteroid's 1.4-lunar-distance pass by the Earth, from an observation that used the Arecibo telescope to transmit a 300-kilowatt beam of radio energy toward the asteroid and the Robert C. Byrd Green Bank Telescope, (GBT) in West Virginia to receive the echoes. The image summed echoes recorded over about three minutes. The intrinsic resolution of the image is about eight meters (25 feet). ...
