Abstract
An imaging apparatus (100, 300) comprising: an optical encoder (150, 350) configured to provide an encoded image of an object (110) with at least one mask pattern; a rotating mirror (170) configured to receive and project said encoded image; and an image sensor (180) configured to receive said encoded; wherein, said rotating mirror (170) is operable such that a plurality of encoded images, which are individually projected by said rotating mirror (170) are spatially shifted as a result of rotation of said rotating mirror (170), are swept across said image sensor (180).

An imaging apparatus comprising:
- an optical encoder configured to provide an encoded image by encoding an image of an object with at least one mask pattern;
- a rotating mirror configured to rotate and to receive and subsequently project said encoded image;
- and
- an image sensor configured to receive said encoded image projected by said rotating mirror;
- wherein, said rotating mirror is operable to single-directionally rotate a rotation angle such that a plurality of said encoded images, which are individually projected by said rotating mirror at any rotation moment and are spatially shifted as a result of rotation of said rotating mirror, are swept across said image sensor for a single image acquisition.
A method of high speed imaging, comprising:
- generating an encoded image by encoding an image of an object with at least one mask pattern;
- receiving and subsequently projecting said encoded image by a rotating mirror configured to rotate;
- and
- receiving said encoded image projected from said rotating mirror by an image sensor;
- wherein, by single-directionally rotating said rotating mirror a rotation angle, a plurality of said encoded images, which are individually projected by said rotating mirror at any rotation moment and are spatially shifted as a result of rotation of said rotating mirror, are swept across said image sensor for a single image acquisition.
