Educational PSP/TSP System

(Product ID: RM-01, RM-02)

An educational version of our Pressure and Temperature Sensitive Paint system is available.  This system provides high spatial resolution, excellent dynamic range, but lower data capture rates than our higher-end systems.  For applications where time in the wind tunnel is not a critical issue, it represents an excellent cost/performance trade-off.  This system provides full capability for undergraduate demonstrations, training, and laboratory exercises.  It will support all but the most demanding graduate and faculty research programs requiring distributed pressure and temperature measurements in wind tunnel environments.  The system employs proven ISSI LED technology for excitation of the luminous probes in the paints.  The camera is based on a color CCD chip, eliminating the need for a filter wheel when using bi-luminophore paints.  The OMS-Lite software package is easy to use and fully supports the educational and research capabilities of the PSP/TSP system.

 Hardware


ISSI Color Camera

(Product ID: PSP-CCD)

The ISSI color camera uses a CCD chip with 2-Mpix resolution.  The camera body is 2.5-inches long by 2-inches tall by 2-inches deep.  The small size will allow the camera to be mounted in the tight spaces close to the tunnel wall, and optimize the view of the model.  The integrated heat sink provides proper cooling without the noise of an internal fan.  

The binary paint formulations have been optimized to perform with the camera.  The camera can function with single luminophore PSPs as well, the only drawback being 1/4 the resolution of the full array.  In this case, the final PSP image is about 480000 pixels.  For users only using single luminophore PSPs, the monochrome version of the camera will provide better spatial resolution since the entire array is utilized.

Featuresccd

  • Array size (pixels): 1608 x 1208 ==2 megapixel
  • Frame Rate: 35/44 fps (normal/overclock)
  • Pixel Size: 7.4 x 7.4 µm
  • Gigabit Ethernet Interface
  • Dynamic Range: 14-bit
  • Lens Connection: C-mount 
  • Sensor: 2/3-inch format

Pulse/Delay Generator

(Product ID: PSG-2)

The PSG-3 is a four channel pulse/delay generator used for controlling the timing of experiment parameters and can be used as an experiment master clock or externally triggered (or gated) by an external event. 
Pulse width, delay, repetition rate, and other timing parameters are controlled by a simple user interface (or also by an internet browser interface) and communication is via ethernet connection or USB.

Parabolic Reflector and Diffuser

(Product ID: LM2X-10R40-D)

     The LED reflector and diffuser is a 10-degree reflector for concentration of output light from an LED.  The intensity output on the illuminated surface is 2-3 times greater when using the reflector.  The diffuser creates a uniform light distribution and reduces the structure pattern of the individual LEDs.

Package Options


The PSP system package has several options for purchase.  Depending on the size of the facility the system will be used in, some different optical kits may be appropriate.  Addidtional LEDs and cameras can also be added to systems and seamelessly integrated.  Building a system with the appropriate hardware for your facility is paramount to the success of the results. For questions about your application, please contact ISSI for technical assistance.

Optical Kits

Camera lens and filter kits are included for use with the PSP system.  Using the right filter for a particular paint is essential to the test.  Kits include the filters, lenses and adapters.  There are two options for optical kits.  One kit is geared towards small c-mount lenses for close-up applications or where space is limited.  The other kit is for small to large applications and offers remote control of the included lenses.
