1-1 Overview of the IG Series
This unit receives laser light from the transmitter. The receiver uses a CCD (Charge
Coupled Device) as the receiving detector. The CCD is a linear array of light receiving
elements. When a target is placed between the transmitter and receiver, a shadow is
caused on the receiver. By detecting the light to dark and dark to light transitions, the unit is
able to measure those areas accurately.
For details, refer to "4-3 Setting the Measurement Sensitivity" (page 4-44).
