When I point my laser pointer (regardless what color) at a bright surface, the bright spot reflects and acts as a bright light source.
But the area illuminated by the laser has a strange speckle pattern. No, there is no error in my eyes as I see the same surface when illuminated by an incandescent / fluorescent / led lamp woth the same color without these speckle pattern.
Why this speckle pattern ?
