Appeal No. 1997-2990
Application 08/260,318
The disclosed invention pertains to an optoelectronic
CCD line scanner camera which provides a loss-free arrangement
for lengthening scan lines and avoiding optical and
diffraction effects with the aid of a special beam splitter
and a number of linear CCD detector arrays.
Representative claim 1 is reproduced as follows:
1. A loss-free arrangement for lengthening scan lines
and avoiding secondary optical and diffraction effects in a
single optoelectronic camera with the aid of a special beam
splitter and a number of linear CCD detector arrays, wherein
a single optics lens system (O) of the optoelectronic
camera is followed by an optical beam splitter (ST), including
alternatingly transparent segments (ST , ST , ...) with1 3
substantially complete transmission and reflective segments
(ST ,
2
ST , ...) with substantially complete reflection segments (ST -4 1
ST ,...), the transparent segments and the reflective segments
4
being interleaved via intermediate transition zones providing
a gradual change from full reflection to full transmission;
from the number of linear CCD detector arrays (CCD ,
1
CCD , CCD CCD , ...), two long line modules (M , M ) are2 3 4 1 2
formed, so that in each long line module, free interstices
(FR) between the linear CCD detector arrays are shorter than
the length of a light-sensitive segment of one linear CCD
detector array;
two long line modules (M , M ) each are disposed, one1 2
following the beam splitter (ST), below its transparent
segments, (ST , ST , ...), and the other one laterally of this1 3
beam splitter (ST) next to its reflective segments (ST , ST ,2 4
...),
such that the centers of the linear CCD detector arrays (CCD ,
2
CCD , ...) of the one long line module (M ) coincide with the4 2
