Abstract
The invention relates to an optical device (1) for enhancing the resolution of an image, comprising: a transparent plate member (10) configured for refracting a light beam (20) passing through the plate member (10), which light beam (20) projects an image comprised of rows and columns of pixels (40), a carrier (50) to which said transparent plate member (10) is rigidly mounted, wherein the carrier (50) is configured to be tilted between a first and a second position about a first axis (A), such that the plate member (10) is tilted between the first and the second position about the first axis (A), whereby said projected image (30) is shifted by a fraction (ΔP) of a pixel, particularly by a half of a pixel, along a first direction (x), and an actuator means (60) that is configured to tilt the carrier (50) and therewith the plate member (10) between the first and the second position about the first axis (A).
