An upgrade to the IceCube Neutrino Telescope is currently under construction.
For this IceCube Upgrade, seven new strings will be deployed in the central
region of the 86 string IceCube detector to enhance the capability to detect
neutrinos in the GeV range. One of the main science objectives of the IceCube
Upgrade is an improved calibration of the IceCube detector to reduce systematic
uncertainties related to the optical properties of the ice. We have developed a
novel optical camera and illumination system that will be part of 700 newly
developed optical modules to be deployed with the IceCube Upgrade. A
combination of transmission and reflection photographic measurements will be
used to measure the optical properties of bulk ice between strings and refrozen
ice in the drill hole, to determine module positions, and to survey the local
ice environments surrounding the sensor module. In this contribution we present
the production design, acceptance testing, and plan for post-deployment
calibration measurements with the camera system.
