=Experimental Apparatus=<br />
The camera is formed by pin-hole opening that allows light to enter a thus create an image of the object at a distance of 150mm. The target made up of a translucent plastic that allows a digital camera to capture the picture created on it. The pin-hole's opening must be previosly selected (200 um, 350 um, 1mm, 1,5mm and 2mm). The object can be moved in relation to the camera, creating a distance between 100mm and 315mm. This object is formed by 16 LEDs (red, green, blue), placed in a way that allows the displaying four equal-sided triangles. The target has a milimetric scale to help establishing the relation between image pixels and real length. This means a simple graphics program (like [http://www.gimp.org gimp]) can be used to count the pixels.<br />
