The invention provides a sensor unit (100) comprising a sensor array (120) having at least 100×100 sensor pixels (125), a lens system (200), and a light transmissive sensor window (300) comprising optical structures (320), wherein the light transmissive sensor window (300) is configured at a window distance (d) from said sensor array (120), wherein the lens system (200) is configured between the sensor array (120) and said sensor window (300), and wherein an object plane (OP) and an image plane (IP) defined by said lens system (200) and sensor array (120) have an object-image plane distance (d1) selected from the range of 0.1*d-2*d, wherein the optical structures (320) are configured in a pattern, wherein the optical structures (320) have one or more dimensions selected from length (L), width (W) and diameter (D) selected from the range of 50 μm-20 mm, and wherein neighboring optical structures (320) shortest distances (d2) selected from the range of 0-50 mm.
