Lens R&D and SystematIC Design B.V. are currently involved, in frame of an Artes AT program, in designing a small true digital Sunsensor, intended to have an as large as possible Field Of View (FOV). Adding another 10 degrees to the common 60° on axis field of view will even provide a redundant full spherical coverage with only 8 sensors, (instead of the required 10 sensors when a sensor with 60° FOV is used). This conclusion prompted an investigation into the possibilities to increase the FOV to 69° on axis. During the following design considerations however, several optical issues were encountered, actually leading to a proposal to reduce the FOV to 62° in diagonal (54° on axis). This paper focusses on these issues and effects, like polarisation dependent reflection, Sun spot spreading and shadowing effects of on-chip interconnects.
