Spatial Light Modulation (LCOS) is the basic core technology of the AR/VR/MR technology display part and the commanding height of the AR/VR/MR industry development. As a benchmark for AR head-mounted display devices, Google Glass and HoloLens use LCOS microdisplay technology. AR glasses need to achieve a big breakthrough, which is to enable users to wear comfortably, carry around, and display a large screen in front of the eyes, but also to render realistic 3D content into the real world, creating an immersive experience. Judging by the comprehensive display effect (brightness, FOV, resolution), volume, weight, etc., the diffraction waveguide is the future development trend of AR display. In the next 3 to 5 years, it can be used with the diffraction waveguide and can only meet the comprehensive display effect technology.

In today's society, computer multimedia technology and digital communication technology are developing rapidly, and we have entered the era of informationization. With the increase of the amount of information, the means of processing information has become more and more advanced. Especially in recent years, visual information technology has been widely used in network management dispatching centers, command and control centers, large conference rooms and other places. A variety of electronic devices with a large screen projection wall as the core enter the network management dispatching center, command and control dispatching room, conference room, studio and monitoring room. Based on the requirements of users, we designed the LCOS large-screen display system based on the principles of system rationality, advancement, reliability, practicability and scalability.

LCOS display technology's ultra-short-focus laser projection, with high color reproduction and high color saturation and 4K HD, can be directly placed on white flat wall or glass, without the need for a dedicated screen, you can easily achieve 100 Oversized screens above the inch.

The 360-degree holographic phantom imaging system uses a mid-air imaging system that suspends three-dimensional images in the real scene of the cabinet. The 360 holographic phantom imaging system consists of a cabinet, a beam splitter, a spotlight, and a video playback device. Based on the principle of spectroscopic imaging, a special process for constructing a 3D model is performed on the real shot of the product, and then the product image or product 3D model image is taken. Superimposed into the scene, it constitutes a product and display system combining dynamic and static. You don't need people to wear any polarized glasses, you can enjoy 3D phantom stereo display effects without any restraint, giving people a visual impact and a strong sense of depth.

The Oral Surgery Training Simulator is a multi-functional virtual reality oral surgery simulator that combines vision and vision to truly restore the oral pathology of periodontal patients. Medical institutions and students can experience real visual feedback and force perception during operation. Feedback, effective training of basic periodontal surgery skills such as squatting and underarm treatment to achieve the same effect as real case teaching. Mainly used for oral basic teaching, surgical skill training, surgical operation assessment, real-time realistic rendering in 3D scenes of surgery, real-time, fine, force feedback, etc., the device has significant technical advantages.

Fire hazard is not as far away as people aware. Therefore enhancing the safety awareness and disaster prevention skill of the general public, especially young people is crucial. VR technology would play an important role in this respect.

The ophthalmic surgery simulation training system is designed for the simulation training of medical students or novice doctors in ophthalmic surgery. The microscope and multiple sensors capture video and gesture of the operator during the entire ophthalmic surgery training process, and analyze on the data simultaneously to improve training efficiency. The system includes a primary eyepiece and a secondary eyepiece, allowing the instructor to monitor the operator either via the secondary eyepiece or via the tele-training system from a remote classroom.

The ophthalmic surgery simulation training system is mainly used in the simulation training of medical students or novice doctors in ophthalmic surgery. The simulated surgical microscope and multiple sensors perform video capture and gesture capture for the entire process of ophthalmic surgery training, and then standardize the student's surgical operations through image analysis and gesture analysis to improve training efficiency. The system includes a primary and secondary eyepiece, and the operator performs a surgical training operation under the primary eyepiece. The entire training process can be viewed and guided in the remote classroom through the secondary eyepiece or through the medical surgical teaching system.

You could experience a vivid representation of a real surgery by wearing AR glasses. This system allows multi-person collaborative interaction and gesture control to pause, zoom, rotate and move. Other users can see their entire interaction process simultaneously, while other users can interact. Throughout the 3D operation, the TOF sensor can be used for spatial positioning and mapping with other AR glasses and cameras. Multi-channel communication can be performed via the Internet or a local area network, and the surgical process can be projected by a laser projector to allow other participants to watch the learning process. The product can also be used in telemedicine, AR surgery simulation, distance education, teleconferencing and other fields.
