A thermoplastic film for a laminated-glass pane, having a non-linear continuous wedge insert in both a vertical and horizontal direction in some sections, is described. In the vertical direction, the laminated-glass pane is, from the perspective of an observer, further at a lower end than at an upper end. In a laminated-glass pane equipped with the thermoplastic film, the thermoplastic film is located between two glass layers. The thermoplastic film has at least a first section having a wedge angle profile that is continuous and non-linear in the vertical and horizontal direction, such that ghost images from a head-up display are minimized in the region of the first section. The thermoplastic film also minimizes double images in transmission in the first section and in further sections.

A pair of optical prisms arranged in a complementary relationship provides for anamorphic magnification and cooperates with a refractive or diffractive element having at least one axis of effective cylindrical curvature, wherein each at least one axis of effective cylindrical curvature and the apexes of the pair of optical prisms are all substantially parallel to one another. The refractive or diffractive element generates an aberration as a result of rotation thereof about an axis parallel to the at least one axis of effective cylindrical curvature that at least partially compensates a corresponding aberration generated by the pair of optical prisms.

A diamond-shaped lens system includes: a half diamond-shaped lens including refractive material and having a first surface, a second surface and a third surface for refracting incident light beams from an object having a width of X, from the first surface towards the second surface; a first reflective material positioned at the second surface of the half diamond-shaped lens for reflecting the refracted light beams at a first angle toward the third surface; a second reflective material positioned at the third surface of the half diamond-shaped lens for reflecting the light beams reflected from the first reflective material toward the first surface to exit the first surface at a second angle toward the third surface to form an image of the object with a width Y; and; an apparatus for processing the image of the object to reduce chromatic aberrations.

Devices and methods for multiplexed imaging are provided. In one embodiment, an imaging device can simultaneously direct light of a same spectrum from each of a plurality of image channels onto an image sensor to create a multiplexed image on the sensor. Each image channel can collect light from different portions of an extended field of view or from the same portion with different perspectives. The device can also include one or more encoders to encode light from the channels prior to detection. The devices and methods described herein can also include disambiguating a captured multiplexed image to create images for each of the plurality of image channels. Disambiguated images can cover the extended field of view at a high spatial resolution despite using only a single small format image sensor, or can produce stereo or 3D images having the full resolution of the sensor.

An anamorphic directional illumination device may provide a near-eye display apparatus or a vehicle external light device. The anamorphic near-eye display device comprises a spatial light modulator with asymmetric pixels; an input transverse anamorphic lens; and an extraction waveguide that passes input light in a first direction between a polarisation-sensitive reflector and rear guide surface to a lateral anamorphic reflector, and to reflect the light back through the extraction waveguide to output through the front guide surface. Deflection features are arranged on the front side of the polarisation-sensitive reflector to deflect the reflected light towards the pupil of a viewer, maintaining the directionality of the fan of light rays from the SLM and anamorphic imaging system. A thin, transparent and efficient anamorphic display apparatus for Augmented Reality and Virtual Reality displays and for scene illumination is provided.

Single fold optical systems that include a power prism and a lens stack including two or more refractive lens elements. The single fold optical system may provide a long mechanical back focus without increasing the Z-height of the optical system. Providing power on the prism may reduce the optical total length and reduce the X-length of the optical system. The single folded optical systems may provide reduced Z-axis height and reduced X-axis length when compared to conventional double folded optical systems with similar optical characteristics. In addition, the optical systems may include an anamorphic lens that is oriented to correct for astigmatism caused by surface errors of the reflective surface of the prism.

A camera for recording 3D image data using a light sectioning process is provided that has an illumination unit to project a light pattern in a focal plane, an image sensor having a plurality of light reception elements in an image plane, a reception optics upstream of the image sensor and having an objective plane, and a control and evaluation unit that is configured to generate the 3D image data by evaluating the light pattern in a recording of the image sensor, wherein the image plane is tilted with respect to the focal plane. In this respect, the reception optics has at least one metaelement here that compensates an oblique light incidence on the light reception elements.
