This has to be baloney. Light *has* to strike the sensor at an oblique angle or an image will not be formed! Only light along the axis of the lens will be perpendicular to the array, and of this light, only the ray on axis will be perpendicular. Of the rays forming a dot on the array along the lens axis, even light from the edges of the aperture will be somewhat oblique. Now, the question is: What oblique angle is acceptable to the array? This cannot be determined from the inaccurate cartoon provided.
