PLD-2SXY driver locks two resonant scanners (type SC, except for the subminiature scanners) each of a different frequency in a MASTER/SLAVE phase locked mode to generate a repetitive pattern (e.g.: a raster scan or Lissajous patterns).
An X,Y raster scan system can be generated by locking two resonant scanners in a master/slave mode.
The system consists of scanner "X" (high frequency) and scanner "Y" (low frequency). The two scanners are ONE FIXED FREQUENCY each, picked from the range of 10 Hz to 16 kHz (e.g.: 10 KHz).
Scanner "X" is operating at its resonant frequency (Fx).
Scanner "Y" is phase locked to scanner "X" in a MASTER/SLAVE mode. The phase relationship to the master scanner is set by the factory to customer's requirements (0° to 360°) and is front panel adjustable in the range of +/-45° min.
The ratio of the frequency of scanner "X" to the frequency of scanner "Y" (Fy) is "n":
n = Fx / Fy
where "n" is a whole number and is factory set per customer's requirements.
The PLD-2SXY-110 or PLD-2SXY-220 driver is a fully integrated boxed driver for 110V or 220V (please specify). The driver has front panel controls for amplitude and phase and internal power supplies. The dimensions of the cased driver are: 12 X 10 X 3.8"
The PLD-2SXY-110/220 is a version of the boxed driver with a line switch selector for operating from a line voltage of 110Vac or 220Vac.
The PLD-2S-PC driver is a printed circuit board level driver which requires an external +/-15V DC power supply.
The system can be used as a "stand alone" unit or can be incorporated into an instrument or a system. Although the scanners can be used in a large temperature range this driver is not recommended for use in temperature sensitive applications.

APPLICATIONS:
X,Y scanning systems provide inexpensive high performance for applications involving beam deflection: TV, HDTV, for 2D and 3D scanned objects, for color separation, to generate images stored in computer memory and project them onto a screen, to generate data and/or transfer data directly to production units (CAD/CAM) and for inspection systems to name a few. The scanning systems are used for robotics, medical non-invasive research and testing, transportation, non-impact printing and laser scanning, inspection systems and high speed, high resolution display system and machine vision.
