Embodiments of the disclosure provide an optical sensing system, a method for adjusting a receiving aperture in the optical sensing system, and an adjustable iris in the optical sensing system. The exemplary optical sensing system includes a transmitter configured to emit light beams to an environment. The optical sensing system further includes a receiver configured to receive the light beams returning from the environment. The receiver includes an adjustable iris including a plurality of rotary blades each driven by a MEMS actuator. The plurality of rotary blades collectively form an adjustable receiving aperture for the returned light beams to pass through. The plurality of rotary blades are configured to rotate in order to vary the adjustable receiving aperture during operation of the optical sensing system. The optical sensing system also includes a detector configured to detect the light beams that pass through the adjustable iris.

One embodiment of a method for restricting laser beams entering an aperture to a chosen dyad and measuring their separation. The method works with frequency-modulated coherent light, and one embodiment uses a moveable, variable-aperture apparatus (FIG. 1) in conjunction with a converging lens (6) and a detector (7). Key elements of other embodiments are described.

A light attenuating device includes a housing, a first filter, a first motor configured to move the first filter, and a pneumatic actuator configured to move the first filter to either be in contact with the housing or to not be in contact with the housing. The filter includes multiple slit openings that vary in width such that the amount of light that passes through the multiple slit openings varies as the first filter is moved. The light attenuating device may also include a second filter and a second motor configured to move the second filter. A method of light attenuation is also disclosed that includes adjusting the position of a filter such that a portion of the filter is irradiated by a radiating beam, and while maintaining the irradiation of the portion of the filter, moving the filter to be in contact with a thermally conductive object.

The present application provides an aperture assembly. The aperture assembly is used in an optical lens system. The aperture assembly includes a plate including a hollow portion and a non-hollow portion. The hollow portion is configured to define an aperture of the optical lens system, wherein the contour of the hollow portion has a non-circular shape. The aperture assembly can prevent the size of the aperture from being reduced as the size of the plate is reduced in a case that a circular aperture is applied to the plate. The present application also realizes an aperture adjustment for a non-circular aperture.

Aspects of the present disclosure include systems, methods, and devices use a controllable matrix filter to selectively obscure regions of an image sensor's field of view. The controllable matrix filter is a physical component that may be placed in front of an image sensor and, in certain situations, one or more regions of the otherwise transparent matrix filter may be selectively configured to have an increased optical density such that the one or more regions become opaque thereby blocking out certain regions of the image sensor's field of view. In this way, the controllable matrix filter may be used to mask out certain regions in an image sensor's field of view that may present processing difficulties for downstream systems that utilize information from the image sensor.

An adaptive filter system and a method for controlling the adaptive filter system are described herein. The system can includes one or more filters to attenuate incoming light. The one or more filters can be moved by one or more actuators. The method can capture image data from an imaging device through the one or more filters. Information can be determined from the captured image data. The one or more filters can be moved to a position for capturing image data based on the information.

Embodiments pertain to an imaging system configured to reduce or prevent the effect of unwanted specular reflections reflected by specular surfaces located in a scene. The system comprises at least one image acquisition device for acquiring a scene image comprising a specular surface providing specular light reflections. The at least one image acquisition device comprises at least one first image sensor and imaging optics having an optical axis for guiding light received from the scene along the optical axis onto the at least one first image sensor. The system further comprises at least one polarization filter operably positioned between the at least one first image sensor and an object. The system is configured to determine a polarization filter orientation such that an amount of specular light reflections incident onto the at least one first image sensor is reduced or eliminated.

Disclosed are a reflective color filter substrate and driving method thereof, and a display panel and a display device. The substrate includes color-resist elements in an array, each color-resist element includes a first and second electrode arranged opposite to each other, and a color-resist structure located between the first and second electrodes; and in each color-resist element: the first electrode is a light-transmission electrode; the first and second electrodes are configured to generate a first electric field, and the color-resist elements are configured to be driven by the first electric field to reflect light rays incident on the first electrode as monochromatic light; and the first and second electrodes are configured to generate a second electric field, and the color-resist elements are configured to be driven by the second electric field to reflect the light rays incident on the first electrode as hybrid light of monochromatic light and white light.

An electronic device includes a first housing, a second housing, an accommodating space and a lens module. The second housing is connected to the first housing and includes an arc edge. The accommodating space is formed between the first housing and the second housing and includes an arc area having a position corresponding to the arc edge. The lens module is located in the accommodating space, matches the shape of the accommodating space, and includes a bottom case, a side case, a top case, an internal space and a photography unit. The side case is connected to the bottom case and includes an inclined surface area which is provided in the arc area. The top case is connected to the side case and includes a top opening.

A lens adjustment device includes a base assembly, a lens assembly, a light blocking member and an elastic member. The lens assembly is disposed on the base assembly and is rotatable relative to the base assembly along an axis. The light blocking member is disposed between the base assembly and the lens assembly. The light blocking member is rotatable relative to the lens assembly and the base assembly. The light blocking member is movable along the axis between a first predetermined position and a second predetermined position. The elastic member abuts against the light blocking member to provide an elastic force for moving the light blocking member from the second predetermined position toward the first predetermined position such that the light blocking member abuts against the base assembly.
