Abstract: A laser light source shutter system includes a light source, a variable focus optical element to transmit a beam emitted from the light source, a pinhole located on an optical path through which the beam travels from the variable focus optical element, and a controller to control a transmission and blocking of the beam by controlling a focal length of the variable focus optical element to be equal to a distance between the variable focus optical element and the pinhole or to be equal to other distances different from the distance. Therefore, a laser light source shutter free from vibration can be realized electronically with a low cost and a high light-blocking rate using a variable focus optical element such as a variable focus lens and a variable focus mirror.
