sample, or both is then collected and analyzed” (column 1,

The Abstract of Birang discloses the following:
A photometer [14] having a plurality of input fibers
to its optical entrance [16], at least one [78] of
which is for transmission of calibration light and
at least one [77] of which is for transmission of
sample light. The exit ends of these fibers are
aligned into a linear array [Figures 7B, 7E and 8A],
thereby producing an effective entrance slit for the
optical entrance of the photometer. The fiber(s)
for calibration light are positioned at the center
of the linear array to avoid miscalibration due to
photometer astigmatism.
Smith discloses a chopperless spectroanalytical system
(Figure 1) that teaches simultaneous detection of a sample
beam 14 and a reference beam 34. The two beams are
“concurrently monitored and compared to compensate for errors
due to source fluctuations and the like” (column 1, lines 49
through 51).
The examiner is of the opinion that the fiber 38 and the
Y-coupler 40 of Lequime are a fiber optic bundle that is
split into a first leg and into a second leg (Answer, pages 3
and 11). The examiner is also of the opinion that it would
have been obvious to one of ordinary skill in the art to use
the fiber optic bundle teachings of Birang in Lequime to
