Light angle selecting light detector device

A method for manufacturing a light angle selecting light detector comprising the steps of:

• providing a detector unit;
• providing a selector unit in a non-transparent material, said selector unit having a first surface and a second surface arranged in parallel and having a distance between each other;
• arranging in said selector unit at least one light path formed as a cavity spanning from a first light passing area having a first area size arranged at said first surface to a second light passing area with a second size arranged at said second surface, wherein said first light passing area and said second light passing area are arranged with a lateral displacement;
• assembling said detector unit so as to receive light selected by said selector unit;
• wherein said selector unit includes a pixelated optical modulator,
• said detector unit is pixelated and constitute a part of said selector unit such that said second surface is arranged on said pixelated detector unit,
• wherein said first and second light passing areas for said at least one sets of light passing areas are realized with a first and second set of pixels located in said pixelated optical modulator and said light detector unit, respectively,
• wherein said optical modulator is capable of switching the pixels between a transparent state and a non-transparent state, and
• wherein said first and second light passing areas are arranged to have a first and a second size, wherein said first size is different from said second size.
