X,Y raster scan systems can be generated by:

Locking two resonant optical scanners in a master/slave mode

Locking a resonant optical scanner with a galvanometer or a polygon in a master/slave mode.

An X,Y raster scan system is generated by two resonant scanners. The [sub]system consists of two resonant optical scanners (type SC) locked in a MASTER/SLAVE mode to generate a raster scan. Scanner "X" is high frequency and scanner "Y" is low frequency. The two scanners are ONE FIXED FREQUENCY each, picked from the range of 5 Hz to 20 kHz. They are small size, light weight, low cost and long life devices. They require low power drive electronics and do not radiate any electromagnetic interference (EMI). The scanners have high amplitude stability and very low amplitude jitters; wobble is <1 arc sec. The scanners are IR, VIS, UV and high vacuum capable (to 10^-10 torr) and can be used in a large temperature range.

Scanner "X" is operating at its resonant frequency Fx. The ratio of the frequency of scanner "X" to the frequency of scanner "Y" (Fy) is "n".

Fx n = ---- where "n" is a whole number and is factory Fy set to the customer's requirements.

The PLD-2SXY driver is fully integrated with front panels controls and internal power supplies. The PLD-2SXY-PC driver is a printed circuit board level driver, which requires an external +/-15V DC power supply.

APPLICATIONS:
X,Y scanning systems provide inexpensive high performance for limitless 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. Many aerospace and military applications are in the IR & UV wavelength, high vacuum or cryogenic conditions.
