1.3 Image Sensor
The Spyder3 Color bilinear camera is based on DALSA‘s dual line scan CCD sensor. The
bilinear sensor has two lines. The first line has red (R) and blue (B) pixel alternatively,
while the second line has all green (G) pixels. There is no gap in between the two lines
and this minimizes any artifact due to spatial correction. The G channel can be used as a
monochrome output. The sensor has a 2 tap output.
