Position sensitive device with Gaussian response

Much work has been done in improving the linearization of position sensitive devices, PSDs. However, a novel way of position detection using Gaussian filters has recently been developed. An obvious extension of this approach is possible via the electro-optical implementation of the Gaussian filters. This thesis proposes a PSD that has such a Gaussian output response to an incident light spot moving across its surface. The proposed device is based on a simple and inexpensive p-n junction. The device is simulated using finite-difference frequency-domain numerical analysis within Matlab
