Application 07/978,223
In regard to the recitation in claim 12 that the
photsensor is a line photo sensor, the examiner stated:
It would have been obvious to use
other known detector arrangements,
such as a line sensor because these
are known sensors which operate in a
recognized analogous manner.
[Examiner's Answer at page 8].
In regard to the recitation in claims 13-17 that the
polarizer or analizer is alternately rotated to fixed
positions or rotated continously, the examiner is of the
opinion that:
"It would have been obvious to either
fix the polarizer to each desired
position and make a measurement o[r]
to rotate the polarizer continuously
and "grab" the measurement as the
polarizer passes the desired position.
Cohn et al appears to at least suggest
both these techniques in column 7,
lines 7-9, Cohn et al mentions
"[p]rior to each measurement, the
analyzer 26 can be positioned", which
at least suggests moving the polarizer
or analyzer to a position and holding
it there until the measurement is
finished. The discussion in Cohn et
al, column 8.[,] line 55 appears to
disclose, or at least suggest,
continuously rotating the polarization
(by means of a rotating half-wave
plate); as the reference does teach
rotating the polarizer, the suggestion
of continuous rotation of the
