APPLICATION

제품정보 PRODUCT INFO

The SC-3 and SC-5 type sub-miniature fixed frequency resonant optical scanners are electromagnetically driven moving mirror device, which deflects a light beam with a sinusoidal motion. The mirror assembly is attached at the center of a torsion spring. The scanning frequency range of the SC-5 type scanner is from 100 Hz to 1500 Hz, fixed at any one value within the range. The scan angle is inversely proportional to the frequency, and is a function of the mirror size. The standard operating temperature is 0°C to +65°C. Other temperature range and vacuum operation are available upon request.

 

 

High device "Q" insures frequency stability, low reaction forces and low electrical drive power. High flexural stiffness provides good resistance to shock and vibration, as well as low wobble, and good scan repeatability. Resonating at the natural frequency makes the device an excellent candidate for long life operation for a multitude of applications which require good imaging with minimal distortion. The scanner is especially suitable for dedicated, high volume, OEM industrial applications. The SC-5 type scanner can easily be incorporated in small size and portable instruments.

 

 

Operation at resonant frequency is sustained by a feedback amplifier type ED driver or the AGC driver, using the scanner as a frequency source. The AGC driver also provides a higher amplitude stability (0.01%) and a position output signal.

 

 

The PLD-1S driver will phase lock the scanner to an external clock signal. The PLD-2S driver will phase lock two scanners as a "master/slave" scanning system and the PLD-2SXY driver will phase lock two scanners as an "X-Y" scanning system.

Applications include: barcode readers, laser scanners, image and pattern forming and recognition, printers, biomedical imaging, quality inspection and outer space and environmental research to name a few.



Special vane configurations, modulating waveforms and shapes are available as a special order (consult EOPC). Drive electronics with different package, regulation and power supply options are available. Special pricing is also available for OEM applications.
