holographic waveguide

1 Introduction Nowadays, delay lines have been widely used in signal processing, radar, electronic countermeasure, and other fields. For example, the Unit delay device required for signal processing is a kind of memory, and the dynamic target display (MIT) there must be a delay line-another kind of memory. In electronic confrontation, the signal must be stored for a certain period of time before processing. For example, the receiver's radar signal must be delayed for a certain period of time be

Persistence scene hold is a key feature of the HoloLens holographic experience, when the user leaves the original scene, the holographic objects in the original scene will remain in a certain position, and when the user returns to the original scene, the holographic content of the original scene can be accurately restored. The Worldanchorstore class is the key AP

The World Anchor space Anchor provides a way to keep an object in a specific position and in a rotational state. This ensures the stability of the holographic object while providing the ability to maintain the location of the holographic object in the real world. Simply put, you can add a space anchor to a holographic object so that the

Recently, Microsoft has brought Windows developers the WIN10 version of the HoloLens holographic Glasses Simulator SDK Development Kit tool to develop and debug native WIN10 holographic applications or games directly on PC platforms with the latest released VS2015 Update2 and WIN10 SDK tools. Not to be missed.Built on Microsoft Hyper-V virtualization technology and supporting the use of RemoteFX Physical gr

, the insertion loss is very low and can achieve low cost integration. In addition, AWG reduces the integration of the light source surface array, the use of multiple single wavelength lasers and their coupling can achieve the DWDM target. The key technique of this research is to master the preparation technology of thick-layer waveguide, try to avoid the polarization dispersion caused by stress and even cause the device to rupture. 7 Light Switch Op

different types of optical fiber to assume the responsibility of transmission. Dispersion compensated fiber (DCF) The optical fiber dispersion can widen the pulse and cause the error rate. This is a problem that must be avoided in communication network, and also a subject to be solved in long-distance transmission system. Generally speaking, the dispersion of optical fiber consists of material dispersion and waveguide structure dispersion, material

Gaze gazeIn holographic applications, gaze is the first form of input and is used to locate objects (functions and the PC's cursor pointer are similar). Gazing tells you that the user is looking at the position in the world so that you can determine their intentions. In the real world, you usually stare at the objects you intend to interact with. This way is the same as staring.HoloLens uses the position and orientation of the user's head, rather than

I. Overview of HoloLensHoloLens has the following characteristics1. Spatial mappingWith Microsoft's specially customized holographic processing unit (HPU), the HoloLens enables fast scanning and spatial matching of the surrounding environment. This ensures that the HoloLens can accurately place or present holographic content on the real world surface, ensuring the core AR experience.2. Scene MatchingHoloLen

, especially dark energy, tells us that it is no longer possible to separate the so-called basic theory from cosmology. Dark energy is the biggest problem of quantum gravity. In the past, I thought that black hole entropy is applied to quantum gravity as a black body radiation to quantum theory. Now I think dark energy is the question of black body radiation of quantum gravity. Take a rest and write it at night. My five problems: 1. What is the most common physical representation of the

A new technology that focuses optical signals to unprecedented precision may bring more efficient electronic systems and imaging devices with higher resolution. Engineers at the California Institute of Technology (Caltech) found a way to generate a beam that is smaller than its own wavelength but can transmit the same signal. This technology helps to transmit data through a narrower beam to increase the bandwidth of optical communication. It also paves the way for the emergence of smaller and le

Along with the social progress and development, as well as people's growing material and cultural needs, communication to large capacity, long-distance direction of development has been an inevitable trend of development. Since the light wave has a very high frequency (about 300 million MHz), that is, it has a very high bandwidth to accommodate huge communication information, so the use of optical waves as a carrier for communication has been the goal of people for more than hundreds of years to

1. Preface A cylindrical media waveguide consists of three parts: Core, package layer, and coating layer. Generally, the diameter of the core of a single-mode or multi-mode optical fiber is 5 ~ 15 μm and 40 ~ 100 μm, with a diameter of about 125 ~ 600 μm. The processed optical fiber end face is ideally a smooth plane. However, in reality, the processing of the optical fiber end face often fails to reach the desired state, such as unsatisfactory polish

Last week, Microsoft HoloLens's rival AR glasses Meta 2 was officially shipped, and Microsoft was in the rush. We know that Meta 2 is not only cheaper than HoloLens in price, but also not weak in performance, META2 has a visual angle of 90 degrees, 60 degrees higher than HoloLens. However, the patent now exposed by Microsoft is expected to increase the field of view of HoloLens, but less likely to reduce the cost of equipment.According to the patent document description, according to the patent

The main parameters in OADM The main parameters are: Channel spacing, channel bandwidth, central wavelength, channel isolation, wavelength temperature stability, channel differential loss uniformity. Classification and comparison of OADM node technology The core device of the OADM node is the optical filter device, the wavelength of the upper/lower path is selected by the filter device, and the wavelength routing is realized. At present, it is applied

The following are the two major causes of fiber loss:1 Optical fiber intrinsic lossThe intrinsic loss of optical fiber is the inherent loss of optical fiber, mainly due to the defects of the optical fiber machine matrix material quartz glass and the metal transition impurities and oh-, so that the light in the transmission process to generate scattering, absorption and dispersion, generally can be divided into scattering loss, absorption loss and dispersion loss. The scattering loss is caused by

New Optical Switch Technology Now we have an optical switch based on thermal, liquid crystal, acoustics, and Micro-electromechanical MEM: Micro-o-Mechanical. The thermo-Optical Switch uses an aggregation waveguide with heat regulating. The swap is controlled by thin film heating elements published in the polymer stack. When the current passes through the heater, it changes the heat distribution in the waveguide
