This type of sensor has some issues: 1. low QE (theoretically <50%), the higher the extinction ratio(the better the polarization filtering), the even lower the QE; 2. The polarization filter orientation on sensors are fixed, and thus might not always work well in removing polarized light coming in other orientations.
Is this similar to:

with 4 polarization angle?
Yes, quite similar. So, any company can come to Moxtek and get a polarized version of its image sensor, right?
DeleteWhat about microlens on top of the polarizers? Does Moxtek add them too?

ReplyDeleteIt also appears noise is significantly higher with the applied processing.
