Abstract
Provided are an optical system capable of improving the spatial resolution of hyperspectral imaging and an optical alignment method using the same. The optical system includes a digital micromirror device (DMD) having a rectangular shape, a first cylindrical lens curved to focus and form an image on an axis corresponding to a shorter side of the DMD, and a second cylindrical lens curved in the same axial direction as the axis to collimate light reflected from the DMD.
