          Multi-Wavelength Laser + I-DSP

          With conventional lasers, the transmission spot produces a patchy pattern (as shown in the figure below). This is a laser-specific interference problem caused by the laser having a single wavelength. The IG Series sensor overcomes this problem by using a multi-wavelength laser. Because shadows are formed on the CCD more clearly, the sensor remains highly stable, even with targets that are conventionally difficult to detect (e.g. transparent objects). With the I-DSP (a parallel computing chip) incorporated in the receiver, the sensor can perform data processing at high speed, reducing noise to a minimum.

          Multi-wavelength laser (IG)

          Due to the multi-wavelength laser used, the beam pattern has a more uniform intensity distribution.

          Stable detection of transparent & mesh targets

          Stable detection of transparent & mesh targets

          The L-CCD makes it possible to detect a target based on its position. Edge control and positioning of transparent and mesh targets can be performed stably.
