A laser radar includes: a light source including a laser diode; an optical system configured to shape laser light emitted from the laser diode, into a line beam that is long in one direction, and project the line beam to a target area; and a scanner configured to perform scanning with the line beam in a short side direction of the line beam. The laser diode is disposed such that a fast axis of the laser diode extends along a direction corresponding to the short side direction of the line beam.

Electrical connections are created between the actuator frame of a piezoelectric MEMS scanning mirror system and the substrate separate from the structural adhesive creating the mechanical bond between the actuator frame and the substrate. A structural bond (with no conducive properties) is formed between the actuator frame and the substrate. After the bond is fully formed, separate electric connections can be created by one or both of: 1) coating the actuator frame with a coating that enables a surface of the actuator frame to be wire bondable and creating a wire bond between the actuator frame and the substrate; or 2) depositing a trace of conductive material on the outside edge of the mechanical bond between the actuator frame and the substrate and a final protection layer may be applied over the conductive trace to protect the trace from mechanical or environmental damage.

A convex integrated vehicle inspection and security system embodying a convex parabolic mirror placed at a 45-degree angle and operatively associated with an image capture device capable of capturing a series of image strips at frame rates of up to 900/second. The single image capture device collects light and images using the convex mirror such a way that the composite image of the image strips can be presented as a panoramic image, wherein the panoramic image is displayed as a rectangle where the horizontal direction represents the width of the undercarriage of the vehicle.

The present invention relates to a stereo eye tracking technique. The eye tracking device comprises a processing unit configured and operable for receiving at least one image being indicative of a user's eye; identifying in the image a first data being indicative of pupil's parameters; receiving a second data being indicative of an alternative eye tracking, wherein the second data is more accurate than the first data; and correlating between the first and second data and determining a three-dimensional position and gaze direction of the user's eye.

The image display apparatus includes a light attenuation section that reflects a portion of light emitted from a light source and a scanning section that scans the light reflected by the light attenuation section. The light attenuation section transmits a portion of light emitted from the light source. The light attenuation section has reflectance and transmittance and the reflectance is smaller than the transmittance. The image display apparatus further includes a light receiving element on which the light transmitted through the light attenuation section is incident. The image display apparatus also includes a control section that controls activation of the light source in accordance with detection results of the light receiving element.

In one embodiment, an integrated light transmission/reception optical system module includes a light receiving lens, a light source, and a light transmitting mirror. The light receiving lens receives light, concentrates the received light on a light detector disposed at a rear position, and has an optical path groove formed to be directed from a circumference to a central portion and formed to expose a front side. The light source outputs a pulse laser along the optical path groove from the circumference of the light receiving lens toward the central portion of the light receiving lens. The light transmitting mirror is disposed within the optical path groove, is located on a path of the pulse laser, and reflects in a front direction the pulse laser outputted from the light source. Other embodiments are also possible.

Embodiments of the disclosure are drawn to apparatuses and methods for a rotating optical reflector. Optical systems may have a limited field of view, and so in order to expand the area that the optical system collects data from, the field of view of the optical system may be scanned across a target area. The present disclosure is directed to a rotating optical reflector, which includes a transmissive layer which refracts light onto a reflective layer, which has a normal which is not parallel to the axis about which the optical reflector is rotated. The optical reflector may be both statically and dynamically balanced, which may allow an increased size of the optical reflector, which in turn may increase the aperture of an optical system (e.g., a lidar system) using the rotating optical reflector.
