Development of testing procedures for CCD cameras


Charged couple devices (CCDs) are used to convert optical images into electrical signals. Cameras constructed from them can be used in the analyses of the images for metrological or recognition purposes. They have the advantages of being contactless, fast and flexible in operation but as yet no standardized test methods exist for the determination of their performance characteristics. In particular, for metrological purposes, there is a need to develop methods for the assessment of the errors associated with a camera so that these can be compensated for and the accuracies of the instruments enhanced at low cost.
At an early stage of the project, a list of parameters and test methods to be investigated will be discussed and agreed with representatives of industry. The work will cover the development of methods for the full assessment of the performance of both the optical and electrical elements of CCD cameras. Effects of changing environmental conditions (such as temperature) will be studied as well as the capability of CCD cameras to measure moving objects.

In progress.
