Plastic optical fiber volatile oraganic compounds sensorPlastic optical fibers are easy to handle and are cheap in cost. The project uses plastic optical fiber as a guiding region from source to detector. Scattering region is induced on the fiber using polishing techniques to generate a loss mechanism.

Extending the transmission bandwidth of Light Emitting Diodes (LEDs)The bandwidth of LEDs for general lighting is about 10-20 MHz when a blue filter is place in front of a photodiode. The reason for the blue filter is that LEDs for general lighting are in fact blue lights with a yellow phosphor place in front of them. The yellow phosphor acts also as a Low Pass Filter (LPF), which causes the bandwidth of the LED to drop to about an order of magnitude. In order to extend this bandwidth with external electronic circuitry, the equivalent circuit of LEDs needs to be determined. Actually, the equivalent circuit of LEDs is known and the values of the components can be determined by means of a network analyser. However, a network analyser is expensive and the measurement method complicated. As such, a simpler procedure with less expensive measurement equipment needs to be developed. After the specifics of the LED’s equivalent circuit have been determined an electronic circuit counteracts the needs to be developed and implemented on PCB. Towards this end, hands-on training on Printed Circuit Board (PCB) design using the Electronic Design Environment (EDA) RS DesignSpark PCB will be provided. The developed circuitry will be tested with various LEDs and LED lamps.
Advisor: Karel Sterckx
Description: Expected outcome: A low-cost method to determine the values of the components in the equivalent circuit of LEDs. A PCB with circuitry that counteracts the LPF characteristic of the LED and extends the LED’s bandwidth. |
