Abstract
A 3D optical microscope device of a small form factor optical system is disclosed. A transmission optical system device comprises a first lens having a left side disposed in contact with an input plane, and a second lens having a right side disposed in contact with a rear focal plane and disposed at a position spaced apart by a focal length of the first lens. The first lens and the second lens Fourier-transform a light signal incident on the input plane and output the transformed signal to the rear focal plane.
