Abstract
A thin film type image slicer device comprises a main body prism, a flat optical element, and an optical film. A reflective cavity is formed between the optical film and a second surface of the flat optical element; the optical film has an oblique side at an angle θ with respect to a projection direction of a light beam reflection forward direction in the reflective cavity; the light beam repeatedly passes through the oblique side in the reflection forward direction; an image spot is sliced into a plurality of sliced images with the same width; and the plurality of sliced images are linearly arranged in an arrangement direction perpendicular to the slicing direction; and chief rays of the light beam corresponding to each sliced image are parallel to each other. An operating system includes a pre-optical system, the thin film type image slicer device and a subsequent optical system.
