New Web Papers Section added (30/4/13)

We have now added a section for online publications relaring to the Imagex Series of time-gated Imaging systems. Find out more here.

New Website Launched (7/3/13).

We have now updated our website to bring you up to date with new products and developments at PRS. Please visit again to see whats new!

New Pulsed LED Systems (14/2/13)

The PRS9L and PRS4L now replace the old PRS100 pulsed LED lamps. These new lamps use the latest high power LEDs to maximise light output for time-gated detection.

New Imagex Systems Released (3/1/13)

We have now completed a 3 year project to completely redesign the Imagex Time-Gated Imaging system. The gating electronics have now been incorporated into the camera head and the system now works with a single USB2.0 interface for easy interfacing and compatibility with the latest versions of Windows. Please contact us to find out more..

Nanosecond Imaging with Imagex nanoCCD
We have been getting great results on the nanosecond timescale with the Imagex nanoCCD system. We have now been able to distinguish 2 and 4 nanosecond fluorescent samples with ease and perform some fascinating rangefinder experiments! (see below). In the bottom right hand image the colour coding relates to the distance of each individual object from the camera( Blue=Closest Red=Furthest). This contrast arises from the different times taken for the light to travel from the light source and back to the camera after reflecting of each of the objects. The round trip is of the order of a few nanoseconds.



The objects are about 20cms apart from each other. The plastic bottle at the front of the scene is approximately 1/3rd full of water and this appears to add a significant delay to light passing through it possibly due to multiple scattering and reflections.
