INSTRUMENTS SPECIAL POLARIZATION ACCESSORIES COMPONENTS APPLICATION FAQS GUIDE TIMING/DELAY MANAGEMENT MODULES POLARIZATION MANAGEMENT MODULES - 58- General Photonics Corporation 909.590.5473 http://www.generalphotonics.com The FST-001-B is a piezo-driven fiber stretcher with a long optical delay range of up to 3 mm. The device comes complete with a piezo driver packaged in a user-friendly small enclosure. Only +12 VDC is required to power the unit. One attractive feature is that the device is controlled by up to four independent PZTs, so that the customer has the option to drive each PZT individually, for high resolution, or collectively, for large stroke. In addition, each PZT can be controlled either with an analog signal or a 12-bit TTL signal. During analog control, the driving circuit simply acts as a 4-channel voltage amplifier with 30V/V amplification. Alternatively, the output voltage can be controlled by a computer equipped with a digital I/O card, or by a microprocessor. The FST-001-B enables applications from sensing to medical imaging, interferometry, and spectrum analysis. At General Photonics, we stretch the fiber hard to make your work more relaxed.
