An optical system of an under-display camera (UDC) includes: a display comprising pixels having a first periodic structure; an image sensor disposed under a screen of the display; one or more optical elements disposed between the display and the image sensor and configured to form an image of an external scene on the image sensor; and an additional diffraction member comprising an array of elements having a second periodic structure and configured such that the second periodic structure overlaps the first periodic structure by an offset of the elements to redirect a second light which is a portion of a first light corresponding to the external scene transmitted to the image sensor through the display.

Optical system and method for under display camera

A wide-field imaging lens and an optical image capturing device for an electronic mobile device are provided. In the wide-field imaging lens, an aperture stop, a first lens element, a second lens element, a third lens element, a fourth lens element, and a fifth lens element may be sequentially located and optically coupled. A surface of each of the first lens element to the fifth lens element may be an aspheric surface.

Wide-field imaging lens and optical image capturing device for electronic mobile devices

Provided is an optical multi-pass imaging device including an aperture diaphragm (AD), and an optical element block including a front surface facing an object on which the AD is disposed and a back surface facing an image plane, the optical element block being optically coupled with the AD, wherein the optical element block includes at least one lens element, a wire grid polarizer (WGP), a quarter wave plate (QWP), and a cholesteric liquid crystal (ChLC) layer, wherein the WGP, the at least one lens element, the QWP, and the ChLC layer are disposed to provide a predetermined multi-transmission of radiation light from an object side to the image plane.
