Light degrees of freedom can be used to transfer and process information. Even though communication is the most obvious application of optical schemes, it is also possible to perform high speed optical computation. Several optical schemes have been proposed and investigated for this purpose employing one or more degrees of freedom of light like polarization, frequency, time bins and transverse spatial wavefront. In this talk I will describe optical computing schemes using the transverse spatial degrees of freedom and polarization. They are promising for some types of computation due to the existing know-how on the manipulation and control of polarization and transverse spatial wavefront. I will also present the idea of using optical computing to approach a Distance Geometry Problem.
