Abstract

A multiple light source correction apparatus and a method of use thereof are disclosed. The multiple light source correction apparatus (10) comprises a transparent thin plate (1) having a first correction pattern (12), a second correction pattern (13) and at least one third correction pattern (14). The first correction pattern (12) includes a first straight line (121) having first and second end points (1211, 1212). The second correction pattern (13) includes a second straight line (131) and two U-shaped frames (132). The second straight line (131) includes third and fourth end points (1311, 1312). The two U-shaped frame (132) is installed at externals of the third and fourth end points (1311, 1312) respectively. The third correction pattern (14) includes a third straight line (141) having fifth and sixth end points (1411, 1412). The first, second and third straight lines (121, 131, 141) are arranged parallel to each other.
