Workings of An optical mouse
An optical mouse emits a a bright light onto the surface from a light emitting diode (LED) at the bottom of your mouse (this is where the ball of your typical mouse would be at). The light gets reflected by the surface which is detected by a photoelectric cell also found at the bottom of the cell. This cell has a lens which magnifies the reflected light so the mouse can emulate your hand movements with the cursor on your screen. As you move your mouse a pattern of reflected light is formed which is then translated to cursor movements in a chip in your mouse. That means that an optical mouse in entirely electronic and with little moving parts. What is it made up of that allows it to do so?(I was very curious about this.) Above is the inside of an optical mouse and a few main components. What are they? An LED at the back generates red light and shines it horizontally, from the back of the mouse toward the front (from the left to the right of this photo). A plastic light guide...
