Fabry computer controlled

He-Ne laser. The frequency of the shifted infrared beam is locked to this reference Fabry-Perot cavity whose length is fixed. By changing the acousto-optic modulation frequency, which is provided by a computer-controlled frequency synthesizer, we can therefore precisely control the dye laser frequency over a range of 250 MHz centered at any desired frequency. [Pg.860]

Most belt-feeder designs feature a fabric or an elastomer-covered, fabrie-reinforced band, supported by idlers or plates. Materials are sheared from the storage hopper above and delivered to the belt. Feed rates are controlled by adjusting the gate that controls the depth of materials on the belt. More precise control can be achieved by measuring the belt speed and the weight impressed on one or several of the belt idlers to compute and control the weight rate of feed. [Pg.1049]
