Linear polarization example

So I have a pmt that counts photons, producing an xy top image of the point spread function of my lens focusing. Strehl ratio requires comparing the intensity of the airy disk at the focal plane of your lens to an ideal lens with the same NA.

Novel liquid-crystal devices are described that generate linearly polarized light with axial symmetry; the beam propagation axis is the symmetry axis. Such light fields can be characterized by a polarization order number P. For example, P = 1 fields represent radially or azimuthally polarized light. The reorientation of the polarization orientation in these polarization converters is due to the twisted nematic effect and the effect of λ/2 wave plates. A single polarization converter can generate fields of orders 1 and 2. It is shown that one can in principle generate fields of any integral order P by cascading such elements. Devices that generate P = 1 fields are achromatic and can be used as polarization axis finders or as versatile tools for studying birefringent or polarizing materials.

My question is, can I use the image created by the pmt as the intensity for the strehl ratio calculation? Or do I have to somehow convert the collected data into the correct type of data with the correct units? Is there some more elaborate setup required for the strehl ratio measurement?
