The voltage controlled oscillator circuit includes a resonant circuit, with two inductive elements and a variable capacitive element, which is connected to a high potential terminal of a voltage source, and a pair of cross-coupled NMOS transistors, which is connected between two oscillating signal output terminals of the resonant circuit. In accordance with a preferred embodiment, the spacers may be formed utilizing flow-fill deposition of a wet film in the form of a percursor such as silicon dioxide. The plurality of beams passed through the scanning lens are incident on the plurality of compensation lenses, respectively. The second movable node is connected to the second link and is capable of linearly moving and rotating with respect to the second link.
