Abstract

A new analogue technique is proposed as a method of obtaining Fabry-Perot line profiles using an imaging photon detector. The technique employs the principle of replacing software with hardware, which increases speed and in this case removes problems due to quantisation errors. A further advantage of the system is that it allows the profile to be observed as the integration proceeds, something which was not possible using the digitised x and y coordinates. The ability to obtain the profile in real-time is of importance when recording from a light source whose intensity varies with time.
