| DESCRIPTION |
The Phoenix Lander Robotic Arm Camera (RAC) was a variable-focus color camera mounted to the Robotic Arm (RA). It was designed to acquire both close-up images of the Martian surface and microscopic images (down to a scale of 23 micron/px) of material collected in the RA scoop. The mounting position at the end of the robotic arm allowed the RAC to be actively positioned for imaging of targets not easily seen by the Stereo Surface Imager (SSI), such as excavated trench walls and targets under the lander structure. Color information was acquired by illuminating the target with red, green and blue light emitting diodes. Digital terrain models (DTM) were generated from RAC images acquired from different view points. This could, e.g., provide high-resolution stereo information about fine details of the trench walls.
