A near-eye display device includes a display panel and a plurality of light modulation units. The display panel includes a plurality of display pixel units configured to emit display light. The light modulation units are disposed on a light emitting surface of the display panel, and each of the light modulation units is disposed corresponding to one of the display pixel units. Each of the light modulation units is configured to direct the display light emitted from the corresponding display pixel unit to an eye of a user, and a width of the display light directed to the eye of the user is smaller than the pupil size of the eye. The user may still receive clear images when the near-eye display is out of focus because the display light directed to the eye has the width smaller than the pupil size.

The present disclosure describes optoelectronic modules (e.g., hybrid lens array packages) that have multiple optical channels, each of which includes at least one beam shaping element (e.g., a lens) that is part of a laterally contiguous array. Each optical channel is associated with a respective light sensitive region of an image sensor. Some or all of the channels also can include at least one beam shaping element (e.g., a lens) that is not part of a laterally contiguous array. In some cases, the arrays can include alignment features to facilitate alignment of the arrays with one another.

An optical lens assembly includes: a first element group including: a first lens group with positive refractive power, including one or two lenses; a second element group including: a second lens group with positive refractive power, including two or three lenses; an optical element including, in order from a visual side to an image source side: an absorptive polarizer, a reflective polarizer and a first phase retarder; and a partial-reflective-partial-transmissive element; and a third element group including an image source plane. The first element group, the second element group and the third element group are arranged in order from the visual side to the image source side. When the optical lens assembly satisfies a specific condition, the weight of the device can be reduced, the zoom function can be provided, and the image quality can be ensured.

A miniature wide-angle imaging lens has a miniaturization ratio, of a total track length from the center of a first surface to a focal plane by an image circle diameter, with a value less than 3.0. The imaging lens includes, starting from an object side of the lens, a first group of at least three optical elements, a second group including an aperture stop and an optical element immediately in front of or behind the aperture stop, and a third group of at least two optical elements.

An optical zoom including a movable pupil that moves according to a movement law, comprises four successive groups of lenses, the first group and the fourth group being fixed, the second group and the third group being movable and placed between the first and fourth groups, the second group being a convergent group and the third group being a divergent group. In a first variant, the diameter of the movable pupil varies according to a variation law, depending on the movement law of the movable pupil. In a second variant, the optical zoom includes a movable stop, the movable stop moving according to a second movement law, the diameter of this stop varying according to a second variation law, depending on the second movement law of the movable stop.

The illumination lens enables emitting light having a more favorable characteristic with a simpler configuration.
