Appeal 2006-2996
Application 10/066,157
iii) a detection system having a focal plane, to detect light from
different regions across the array emitted in response to the illumination,
when at the reading position, and which generates a resulting signal for each
of the regions across the array; and
iv) an autofocus system which detects and reduces offset between the
different regions of an array at the reading position and a determined
position of the focal plane;
the method comprising:
a) positioning a calibration member having a uniform fluorescent
layer at the reading position so as to receive illumination from the light
system and emit light in response thereto, which emitted light is detected by
the detection system to generate a resulting calibration signal;
b) adjusting a position of the calibration member, when in the reading
position, relative to the focal plane;
c) determining the position of the focal plane from the light detected
at various adjustments; and
d) calibrating a sensitivity of the detection system from the detection
system signals generated from the calibration member.
