During a second time period, the curved reflective element is configured to reflect a second light beam emitted from a second light source to the rotating mirror when the rotating mirror is disposed at a second angular displacement, and the rotating mirror is configured to receive the second reflected light beam and provide a second output light beam along the output optical axis.

A system and method for measuring three-dimensional (3D) coordinate values of an environment is provided. The method including moving a 2D scanner through the environment. A 2D map of the environment is generated using the 2D scanner. A path is defined through the environment using the 2D scanner. 3D scan locations along the path are defined using the 2D scanner. The 2D scanner is operably coupled to a mobile base unit. The mobile base unit is moved along the path based at least in part on the 2D map and the defined path. 3D coordinate values are measured at the 3D scan locations with a 3D scanner, the 3D scanner being coupled to the mobile base unit.

An optical sensing system is provided, including a sensing module, a light emitter, and a light receiver. The sensing module has a substrate, an optical waveguide disposed on the substrate, and a sensing membrane disposed on the optical waveguide for carrying a specimen. The light emitter emits a sensing light to the optical waveguide, and the light receiver receives the sensing light that propagates through the optical waveguide.

Embodiments of the disclosure provide a micromachined mirror assembly for controlling optical directions in an optical sensing system. The micromachined mirror assembly may include a micro mirror configured to direct an optical signal into a plurality of directions. The micromachined mirror assembly may also include at least one actuator coupled to the micro mirror and configured to drive the micro mirror to tilt around an axis. The micromachined mirror assembly may further include one or more objects attached to the micro mirror. The one or more objects may be asymmetrically disposed with respect to the axis to create an imbalanced state of the micro mirror when the micro mirror is not driven by the at least one actuator.

Disclosed are an image capturing system and method. In the image capturing system and method, a light path is changed by controlling a reflection angle of a mirror surface using a rotating mirror so that a single camera obtains consecutive images at various angles or at a wide photographing width.

A scanner for a lidar system is configured to direct emitted light to scan a field of regard of the lidar system in accordance with a scan pattern. The scanner includes a mirror and an actuator assembly. The mirror includes a reflective surface and a rear surface and is pivotable along a mirror axle. The actuator assembly is disposed along the rear surface of the mirror and is configured to exert a torque on the mirror to cause the mirror to pivot about the mirror axle.

An optical sensor includes a radiation part that irradiates an object to be measured with line shaped light; and an imaging part that receives line shaped light reflected by the object to be measured and captures an image of the object to be measured in a predetermined exposure time. The radiation part includes a light generation part that generates the line shaped light, and a light vibration part that irradiates the object to be measured with the line shaped light generated by the light generation part while vibrating the line shaped light in a length direction during the exposure time.
