Title: Light quantity controller
Inventor: HIRAI SHIGETOSHI
IPC: B23K26/06
Filed: 1986-03-24
Abstract: PURPOSE:To control the quantity of a laser beam, etc., by an inexpensive, small-sized device by splitting linear polarized light into two optical paths and multiplexing light whose optical path length is controlled and light which is not controlled. CONSTITUTION:An incident laser beam is polarized linearly by the 1st polarizer 1. This linear polarized light is split into two optical paths according to its polarized components, and a means 4 which controls the length of one optical path is provided on the optical path; and the light whose optical path length is controlled and uncontrolled light are multiplexed into one elliptic polarized light beam. The optical path difference between the two split light beams is adjusted and then the light beams are multiplexed to obtain the optional elliptic polarized light, which is passed through a polarizer 8 set at a proper angle and outputted as linear polarized light, so the quantity of the output light is controlled according to the relation between the elliptic polarized light and polarizer without using any optical crystal element. Consequently, the quantity of light can be controlled without any expensive element such as optical crystal and the small-sized controller with good linearity is obtained.
