Images about THOR

The NASA P3-B aircraft that carried THOR during the 2002 THOR validation campaign and during the 2003 AASI experiment. (Image from http://www.wff.nasa.gov)

A view of THOR inside the P3-B aircraft during the validation campaign in Oklahoma. John Kolasinski (l) and Ken Yetzer (r) uses the console to operate THOR. Most of the instrument lies below the floor, only its shiny metal cover reaches above it, blocking part of the aircraft center aisle.

 

A downward-looking view of the part of THOR that lies below the flight deck. Starting from the lower left corner and moving clockwise through the image, the components are as follows. In the left foreground, we see the data system computer. The little box right behind the computer (and slightly toward the center) is the base plate on which the laser unit is mounted. Further behind we can see the shiny metal box of the laser unit, and behind the laser, the black frame of the beam expander. The camera flash reflects from the aircraft’s down-looking 18 inch port window. To the right of the beam expander lies THOR’s telescope. The black-coated optical fiber bundle couples to the telescope as a single bundle, but then divides into 10 branches, each coupled to one of the 10 channel’s spectral filters. In the right foreground we see the cylindrical housings of the filters.

A view of THOR oriented horizontally in the laboratory, with a 50 cm diameter calibration sphere attached to the telescope.
