Claim 0:
1. An implantable pulse generator casing for connection to a set of leads comprising:
a shell;
a header, operatively attached to the shell, having a set of parallel lead channels;
an optical window, positioned in the shell, adjacent the set of parallel lead channels;
a set of light emitting devices, adjacent the optical window, perpendicular to the set of parallel lead channels;
a set of light detecting devices, adjacent the optical window, perpendicular to the set of parallel lead channels;
an optical signal processor, having a memory, operatively connected to the set of light emitting devices and the set of light detecting devices; and,
the memory incorporating a set of instructions that when executed cause the optical signal processor to:
set a first emitter current on a light emitting device of the set of light emitting devices;
read an initial detector voltage of a light detecting device of the set of light detecting devices;
read a steady state detector voltage of the light detecting device of the set of light detecting devices;
compare the initial detector voltage to the steady state detector voltage; and,
if the steady state detector voltage is less than the initial detector voltage, then increase the first emitter current to a second emitter current.
