FtrDSC - FTR Dual Shutter PIV Camera System
This newly developed camera system, unlike conventional PIV cameras, is suitable for PIV measurement of flow field against a high-brightness background due to plasma emission, combustion, sunlight, etc.
While conventional digital PIV cameras acquire the 2nd particle image only with their electronic shutter disabled, the FtrDSC is capable of activating its dual electronic shutters independently in the acquisition of both 1st and 2nd particle images, thus realizing optimum PIV imaging without CCD saturation.

Features
- Suitable for PIV imaging of the flow field in a high-brightness background due to plasma emission, combustion, sunlight, etc.
- Dual electronic shutters for independent exposure.
- Ethernet interface using ethernet cables and a switching hub.
- High-resolution, high-sensitivity CCD (1.3 megapixel).
- PIV mode for quick installation and easy settings.
- C-mount for versatile lens selection.
- PIV imaging with on-site image rotation and inversion to reduce post-processing.
- "FtrCAM" camera control soft available, customized for PIV measurement.
- Wizard functions in FtrCAM for camera-calibration imaging and particle imaging.
Dual-shutter CCD calibration
Auto-calibration of dual-shutter CCD element
FtrDSC is equipped with the function for auto-calibration of the dual-shutter CCD element. This is essential to PIV measurements, where the sub-pixel accuracy for displacement measurement is required.
