Technology in Education:

Currently I am working on Personal Response System (PRS).PRS technology allows real-time student-lecturer interaction. Instant polling, survey analysis, Student assessment and grading can be done automatically. When a student pushes a button on the PRS in response to a question, a radio signal sends the answer to a receiver and that information is compiled and displayed as a graphic in a MS power-point display.

I am trying to design this system from scratch. RF transmitter, RF receiver that can read data from 100's of transmitters constitute the hardware part. The software consists reading data from receiver, sorting it, compiling it and put it in form of data that can be used for analysis and displaying of results.

It is a complex system with lots of applications and can be used in real time. If you are interested in knowing how the stuff works just email me your query(you can use the contact me link to email) and I will get back to you asap.

Planar Optical Waveguide Devices for Microwave Photonic Applications:

Research into microwave photonics has blossomed in recent years with studies looking at many issues including basic optical-microwave interaction (e.g., radio frequency signal generation), photonics devices operating at microwave  frequencies, photonic control of microwave devices, high frequency transmission links, and the use of photonics to implement various functions in microwave systems.

The Photonics research group at Aston university have demonstrated a number of innovative techniques for processing microwave photonic signals while still in the photonic domain in optical fibre.  For devices operating in an (optically) coherent mode it is difficult to maintain sufficient stability over long lengths of fibre. The use of compact planar waveguide components would eliminate some of these issues. In particular, since several discrete elements can be integrated onto a single substrate, they can be kept stable with respect to each other and the devices will therefore be less sensitive to environmental changes.

This project will involve the application of planar waveguides for microwave photonics. The ability to fabricate planar waveguides makes feasible the development of devices for microwave photonics including optically generating, transmitting, processing and controlling microwave/millimetre wave signals which may have been impractical previously.  Principal areas which we intend to investigate in this program include: the fundamental performance of planar waveguides in the optical microwave domain; the design, fabrication and evaluation of waveguide devices, with an emphasis on using UV inscription approaches; and the optical generation, transmission, processing and control of microwave/millimetre wave signals employing optical waveguides with an emphasis on exploiting Bragg grating structures written in the planar waveguides
