Educational PSP/TSP System

The educational PSP/TSP system provides everything needed to get started with PSP and TSP.  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.

Color CCD Camera

(Product ID: PSP-CCD-C/M)

The PSP-CCD is a 2-megapixel CCD camera.   The camera is small and lightweight at 210g allowing for an array of cameras to be mounted in a tight place for larger scale models and applications.  Communication with the PSP-CCD is via Gigabit Ethernet.  The camera comes in two styles, one with a color array and one with a monochrome array.  The color camera is used in Binary PSP and particle shadow velocimetry applications whereas the monochrome version is used in monochrome PSP or S3F applications.

Pulse/Delay Generator

(Product ID: PSG-3)

The PSG-3 is a four channel digital 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. The PSG-3 replaces the PSG-2 in the ISSI product line.

Pulse width, delay, repetition rate, and other timing parameters are controlled by a simple user interface (or also by any web browser interface) and communication is via Ethernet or USB.


CapabilityTwo dual-channel independently programmable pulse generators

Input trigger thresholding
FeaturesFour high-current TTL outputs

Divide-by-N circuit
ControlMultiple PSG-3s can be cascaded to increase the number of channels

Easy to use software interface or TCP/IP API commands for integration
NetworkingMultiple devices can be connected and simultaneously controlled over a network

10/100 Mbps Ethernet interface
VersatilityMultiple timing bases (s, ms, µs, ns)

BNC inhibit input (TTL high level) to allow the PSG-3 to be gated by an external source.

Parabolic Reflector and Diffuser

(Product ID: LM2X-10R40-D)

The LM2X-10R40-D reflector and diffuser is a 10-degree reflector for concentration of output light from an LM2 series 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.
