A surgically implanted ocular optical array that can be used in both therapeutic and diagnostic applications is described. A device configured to be implanted in an eye includes: an imaging system that receives visible light incoming to the eye; optical source generating circuitry that generates an optical signal based on the light received by the imaging system; and an optical phased array (OPA) that generates and projects an image onto a retina of the eye in which the device is implanted, the image being based on the optical signal generated by the optical source generating circuitry.

A wireless optical communication device is proposed, which includes an optical transmitter comprising: a first optical element dividing an incident beam into a given number of spatially separated beams – channels and forming a grid of spatially separated beams, implementing modulation of the complex amplitude of the spatially separated beams, encoding information data; combining the channels into a single multiplexed beam; an optical receiver receiving the multiplexed beam and comprising a second optical element implementing spatial separation by modes for demultiplexing the received beam and decoding the information; a detector configured to receive demultiplexed modes from the second optical element, a control module including: a control computer setting the parameters of the information signal, a computing unit implementing a discrete Fourier transform of the binary information signal and converting the binary information signal into a discrete set of signals for controlling a multichannel optimizing phase processor and an amplitude controller.EFFECT: forming a phased optical array that generates a synthesized beam having a spectrum of orbital angular momentum modes that correspond to a set of orthogonal modes determined by the Fourier transform of an information signal, propagating the synthesized beam through the free atmosphere, receiving the synthesized beam and demultiplexing the received radiation by an orbital angular momentum mode sorter into a certain number of spatially separated modes corresponding to different modes of the orbital angular momentum of the received radiation and recording them, wherein the set of registered modes at each moment in time determines a binary sequence corresponding to the information signal.2 cl, 12 dwg

The application discloses an optical array system, relates to the technical field of intelligent optical perception and machine vision, and comprises a serializer unit, a power management unit, an optical emission array unit and an optical receiving array unit. The input end of the power management unit is connected with an external power supply, and the external power supply is converted into power supply outputs with multiple different voltage levels. The optical emission array unit is electrically connected with the power management unit and comprises a driver and multiple optical emitters. The optical receiving array unit is electrically connected with the power management unit and comprises multiple optical detectors and a readout circuit. The master control unit is electrically connected with the power management unit, the optical emission array unit and the optical receiving array unit, respectively. The master control unit comprises a timing control module, a signal processing module, a data fusion module and an adaptive compensation module. The application solves the technical problems existing in the prior monocular structured light system, such as sensitivity to environmental light interference, real-time performance and transmission bandwidth bottleneck of massive array data processing, and insufficient adaptive compensation capability for temperature drift and environmental light interference.

This utility model relates to the field of optical component technology, specifically a tangential beam-type dual-head laser lens, including a hemispherical lens, a lens support base, an end connecting post, a bottom support plate, a support plate positioning protrusion, a middle inclined plate of the base, a base end fixing hole, and a lens connecting surface. The collinearity of the hemispherical centers is ≤0.1mm, and the edge tangential gap is ≤0.01mm, which improves the accuracy by 10 times compared to traditional designs, meeting the high consistency requirements of optical arrays. The angle adaptation of the middle inclined plate and the positioning constraints of the ends and bottom ensure that the deformation of the array under vibration and temperature changes is ≤0.02mm, improving reliability by 80%. By adjusting the tilt angle θ and the radius of curvature of the hemispherical surface, it can be adapted to hemispherical arrays of different sizes, such as medical detection and industrial projection, with strong versatility. The "plug-and-play" design of the positioning protrusion and groove shortens the assembly time by 50% and reduces manual debugging costs.

This utility model discloses a precision measuring device for a knee replacement surgery navigation system. The device includes a first test piece and a second test piece. The first test piece includes a first body, at least four support members disposed on the first body, multiple first groove points, and a first optical array. The first end of each support member away from the first body includes a first recess for placing a first laser reflector. The second test piece includes a second body and a second optical array disposed on the second body. The second body includes multiple second groove points and at least three second recesses for placing second laser reflectors. This application, through the first and second recesses for placing the first and second laser reflectors, enables the precision measuring device to be simultaneously located by both the knee replacement surgery navigation system and the laser tracker, thereby allowing the precision measuring device to measure the accuracy of the knee replacement surgery navigation system.
