<p>The sensor (41) has a layer (411) applied on a surface of a receiving component (4) in an optical detection plane and designed as an optical effective diaphragm, where the diaphragm comprises a structure with width of about 0.2 mm. The optical detection plane comprises a surface area of the sensor, and is established exclusively for generation of photocurrent. The layer is made of a metal film i.e. aluminum film. Another layer (412) is arranged on the former layer, where the latter layer is impervious to light with wavelength in a specific region of the optical spectrum. Independent claims are also included for the following: (1) a sensor device (2) a method for recognizing position of an object (3) a computer program comprising a set of instructions for performing a method for recognizing position of an object.</p> |
