The scanning converter supplies two communicative ways:RS-422 and RS-232. Through these ways the main controlling system controls the brightness, contrast, saturation of output pictures.

There is no echo signal, but brightness, scanning line are still exists.

In most of cases, the laser scanning confocal microscopy images, such as fluorescence stained biomedical nuclei, are blurred and have a wide range of brightness and poor intensity homogeneity.
