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.

Abstract: Provided is an optical system which may acquire a hyperspectral image by acquiring a spectral image of an object to be measured, which includes, to collect spectral data and train the neural network, an image forming part forming an image from an object to be measured and transmitting collimated light, a slit moving to scan the incident image and passing and outputting a part of the formed image, and a first optical part obtaining spectral data by splitting light of the image received through the slit by wavelength. Also, the system includes, to decompose overlapped spectral data and to infer hyperspectral image data through the trained neural network, an image forming part forming an image from an object to be measured and transmitting collimated light, and a first optical part obtaining spectral data by splitting light of the received image by wavelength.
