Basic Principle of refractive channel
When there is no lens (0D state), parallel light that has transmitted the collimator lens
passes the 4 pinhole and makes image on CCD. In case of convex lens (lens with
plus diopter), parallel light that has transmitted the collimator lens converges through
the measuring lens, passes the 4 pinhole and then makes image on CCD. On the
other hand, in case of concave lens (lens with minus diopter), parallel light that has
transmitted the collimator lens diverges through the measuring lens and then passes
the 4 pinhole and at last makes image on CCD.
Basic Principle of refractive channel
While a refractive channel is on the home position, an Image channel gets
consecutive images. The images are shown at a screen or are tranfered to an image
processing engine to execute several jobs.
