Pancam
Each Pancam is one of two electronic stereo cameras on Mars Exploration Rovers Spirit and Opportunity. It has a filter wheel assembly that enables it to view different wavelengths of light and the pair of Pancams are mounted beside two NavCams on the MER camera bar assembly.
According to Cornell University it can work with Mini-TES to analyze surroundings.
According to a paper about Mars by JPL, the Pancam system can achieve an angular resolution of 300 microradians, which is three times better than the human eye. It can observe 14 spectral bands, and with two side-by side cameras can generate stereoscopic views of Mars, supporting the creation of large Mars panoramas in excess of 10 Gbit uncompressed. Spirit rover took the highest resolution image ever taken on the surface of another planet up to that time when it landed in 2004.
Optics
The focal length of the camera is 43 mm with a field of view of 16° x 16°. The two cameras are separated by 30 cm and are mounted upside-down relative to each other.Charge-Coupled Device
A 1024 x 2048 frame transfer Charge-Coupled Device detector built by Mitel is used for both cameras. The CCD is front-side illuminated and does not use any anti-reflex or UV-enhancing coatings. Half of the chip is used for storage and readout and is therefore shielded from illumination.Electronics
An Actel Field Programmable Gate Array RT1280 provides the necessary computational abilities for the camera. The signal of the CCD is transformed into a 12-bit digital signal before data processing.Filter wheel
The left camera has filters with the following wavelength:, while theright camera has the filters for:. Each filter wheel is driven by a stepper motor to provide rotation of the wheel.
