Digital Imager (DCAM3-D)

NSSDCA ID: 2014-076K-02

Mission Name: DCAM3


DCAM3-D is a digital imaging system onboard DCAM3. The purpose of DCAM3-D is to provide wide-angle, high resolution scientific observations of the impact event of the Small Carry-on Impactor on the surface of asteroid 162137 Ryugu and send the images by fast digital communication to the Hayabusa2 spacecraft

The 2000 x 2000 pixel, DCAM3-D sensor observes at wavelengths 450–750 nm and has a spatial resolution of 0.65 m/pixel at 1000 m for a full image or 3.25 m/pixel at1000 m for a binned image. The optics have an F value of 1.7 and a 74 x 74 deg field of view.
