The Wide-field Imager for Solar Probe, WISPR, is a system of two visible light
cameras designed to take images of the solar corona and inner heliosphere, as
well as solar wind shocks and other structures as they approach and pass the
spacecraft. The science objectives of the instrument are to understand the
morphology, velocity, acceleration, and density of evolving solar wind
structures when they are close to the Sun, to derive the 3D structure of the
solar corona through which in-situ measurements are made to determine the
sources of the solar wind, to determine the roles of turbulence, waves, and
pressure-balanced structures in the solar wind, and to measure the physical
properties of solar energetic particle producing shocks and their coronal mass
ejection drivers as they evolve in the corona and inner heliosphere.
The Wide-field Imager for Solar Probe consists of two telescopes, designated the
Outer Telescope and the Inner Telescope, mounted on the the side of the
spacecraft behind the sunshield. The telescopes look in the direction of
spacecraft travel off to the side of the Sun from behind the sunshield. The
Inner Telescope views an area from 58.5 degrees; from the center of the Sun to
98.5 degrees. The Outer Telescope views from 98.5 to 156.5 degrees; offset from the
Sun center. The telescopes focus onto two imagers that use radiation-hardened 2K
x 2K Active Pixel Sensor CMOS detectors. The telescope lenses are made of
radiation hard BK7 glass. A combination of baffle systems is used to mitigate
stray light coming into the instruments. The image cadence can be up to one per
second.
