What does kpps mean?
Kpps is the abbreviation of kilo point per
second.
Thus, the performance of the different
scanners (galvanometer scanners, graphic
projectors) which are on the market can be
compared. The higher the scan speed of a
graphic projector the higher the quality of
the projected image. If the projected image
“flickers”, then it is too “big” for the existing
scanner, that means it has too many picture
points and this scanner is not able to
represent it properly.
To make the performance of the scanner
comparable ILDA developed a test pattern.
This test pattern is used to determine among
other things the exact scanner speed. The
higher the number of 8° (!!!), for example
60 kpps @ 8°, the better the scanner and
the better the projected image. 80 kpps @
4° is in turn a worse achievement. Therefore
you should always compare at 8° with the
test pattern of ILDA.
