Super-Fast Line Scanning with a Virtual Line Rate Greater than 1 MHz

Activity: Talk or presentation / LecturePresentation at a conference / workshop for industry or public institution

Description

Traditionally, for fast optical quality inspection of endless material, line-scan cameras are used to meet the
demanding speed and throughput requirements of an industrial production line. Unfortunately, as for speed
and pixel size, the development of line-scan cameras lags behind that of area-scan cameras by several
years. A promising way out of this problem is the use of modern illumination technology with its possibilities
of fast strobing and overdriving of the LED's. In this talk, the development of an extremely fast scanner with
a scanning speed equivalent to a line-rate above 1 MHz is presented. This scanner was enabled by AIT's
fast strobing technology xposure:flash and by integrating a special FPGA module directly into firmware of
an area-scan camera with a fast image sensor. This FPGA module stitches small blocks of a couple of
lines seamlessly together in order to yield an image comparable to that at the output of a line-scan camera
with 1.08 MHz line-rate. The FPGA module was designed at AIT using High-Level-Synthesis (HLS) design
methodology.
