Self-test for IR Sensors

In many industrial applications where IR sensors are used, there is the problem of contamination of the surface of the sensors leading inaccurate measurements. Often the device is replaced, even though the device is still functioning correctly. This project is in close collaboration with a very well know large multinational in the industrial printer industry and the company Exergen. The aim of this project is to explore methods to self-test the IR sensor. This can be used to compensate for the contamination to increase the time between maintenance. This may involve an actuator within the package to simulate the IR to be measured, although other options should be considered. This test can be used at regular intervals during the operation and be developed to be independent of the external IR radiation.

Assignment

The assignment is to develop a self-test system which can be built into the package of an IR sensor. The project will be in close collaboration with the company Exergen. For more information about the company see www.exergenglobal.com, or contact Bram Stelt at [email protected]

Requirements

You should have interest in modelling, design and experimental testing • The sensor should be modelled thermally. • A design for an accessory for air cooling and cleaning should be studied and modelled thermally. • Options for self-test should be studied and modelled. • The solution should be made using a hybrid approach • Integration options into a commercial sensor must be studied and implemented.
