Image Position Correction (MUSIC)
Location of the MUSIC Sensors
The MUSIC sensor array is above the ITB (2), on the right
side of the ITB unit below the K_PCDU. The fan (3) keeps
these sensors clean.
The rear sensor reads MUSIC patterns only
The center sensor reads MUSIC patterns and also
functions as the ID sensor.
The front sensor reads MUSIC patterns only

The unit on left shows the configuration of the middle sensor which performs
double duty as the ID sensor as well as a MUSIC sensor. The unit on the right
shows the configuration of the rear and front sensors in the array that function
only as MUSIC sensors.
The elements in these sensors are:
¾ [1] Emitter. Emits light on the patterns.
¾ [2] Direct reflector sensor. Gathers light emitted by [1] and reflected directly
from the patterns on the ITB.
¾ [3] Diffused reflector. Gathers diffuse light from the sides of the patterns to
achieve more accurate readings especially for Y, M, C. Only the middle
sensor has this extra reflector.
