A vehicular interior rearview mirror assembly includes a mounting assembly having a base portion and a mounting arm extending from the base portion. A mirror head is pivotally adjustable relative to the mounting assembly via a pivot joint having first and second pivot elements. The mirror head includes a mirror reflective element, with the first pivot element disposed at the rear side of the mirror reflective element and fixed thereat. The mounting arm includes a proximal end proximate the base portion and a distal end distal from the base portion, with the second pivot element being at the distal end of the mounting arm. The second pivot element is disposed at a damping element that is received at the distal end of the mounting arm. The damping element and the second pivot element are biased toward the distal end of the mounting arm and away from the base portion.

A light path adjustment mechanism includes a bracket, a light valve, a carrier, a first axis, a second axis and an optical plate member. A surface normal of a surface of the light valve crosses the bracket to define an intersection closest to the surface of the light valve, and the bracket has an end point furthest from the intersection measured in the direction of the surface normal. A distance between the intersection and the surface measured in the direction of the surface normal is smaller than a distance between the intersection and the end point measured in the direction of the surface normal.

An observation device includes: first objective lenses arranged in a row so as to be parallel to one another; second objective lenses arranged in a row so as to be parallel to one another; and image capturing elements for capturing first images formed by the first objective lenses and second images formed by the second objective lenses, respectively, wherein each of the objective lenses is a magnifying objective lens, a first axis of light incident on the first objective lenses and a second axis of light incident on the second objective lenses are parallel to one another, fields of view of the first objective lenses and fields of view of the second objective lenses are arranged alternately in a row on an observation line, and the first images and the second images are arranged in a row in image-forming regions that are disposed at positions different from each other.

An erecting system and a binocular telescope for laser ranging. The erecting system includes a roof half penta prism, a beam splitting prism and an isosceles prism. The beam splitting prism is positioned between the roof half penta prism and the isosceles prism. The beam splitting prism is formed by bonding two right-angle prisms. A beam splitting film is arranged on a bonding surface of the two right-angle prisms. The erecting system not only has simple structure and small occupation volume, but also is convenient in use, can realize the binocular observation and targeting at a measured object, and can display the distance of the measured object in real time in the field of view while observing the object.

A multi-camera vehicular video display system includes an interior rearview mirror assembly having a mirror head that includes a transflective mirror element and a video display screen disposed behind the transflective mirror element. The mirror assembly includes a mechanism that is operable to change orientation of the transflective mirror element relative to a driver of the vehicle. When the mechanism changes orientation to a second position that is tilted away from the eyes of the driver of the vehicle, the video display screen displays video images viewable through the transflective mirror element. When the mechanism changes orientation to a first position that is tilted towards the eyes of the driver of the vehicle, the video display screen does not display video images. The displayed video images are derived, at least in part, from image data captured by at least one exterior viewing camera of the vehicle.

A projector having a curved field lens and a displaced light modulating display. The system includes at least one light source configured to generate colored light beams, and a prism routing the light beams to the display. The curved field lens is coupled to a face of the prism, and the prism and curved field lens together decenter the light beam from the prism face and uniformly illuminate the display. A center of the display is displaced from the projection lens optical axis. The decentered light beam and the displaced display together generate a favorable shifted boresight of the created image. Dimensions of components of the projector are a function of a curvature of the curved field lens. The greater the curvature of the curved field lens, the smaller the dimensions of the components and the overall projector. The projector may be used in eyewear.

An optical system for imaging an object includes a first objective, a first image stabilizing unit, and a first image plane, wherein, as seen from the first objective in the direction of the first image plane, the first objective is arranged first along a first optical axis, followed by the first image stabilizing unit and then the first image plane, wherein the first image stabilizing unit comprises a first optical unit and a second optical unit, wherein the first optical unit is arranged between the first objective and the second optical unit, wherein the first optical unit is embodied so as to be rotatable about a first axis of rotation, and wherein the second optical unit is embodied so as to be rotatable about a second axis of rotation. The second optical unit is embodied as an optical roof edge unit.
