To generate a high resolution image of a three-dimensional workpiece 50, at least one of the two galvanometer-driven mirrors 42, 44 is pivoted upon galvanometer axis g in a known manner. The rotational scanning. successive single axis mirrors have been frequently used to steer a beam along multiple axes [1], a more compact alternative is to use a single two-axes mirror [2-5]. The seller says that the mirrors should be OK with 405 nm lasers, and it has a USB connection and an ILDA connection, i'm guessing the "show card" takes the USB and outputs ILDA. Galvanometer mirrors are used for optical applications such as target tracking, drawing, and scanning control because of their high speed and accuracy. At the same. I n order to create a light sheet, DSLM version scans a beam over the axis using a galvanometric mirror. and reflected from a concave mirror at A, as shown in Figure 38-2.
