Using a facial recognition system, a human face in a digital photo or video frame can be compared to a database of faces. An image’s face features can be located and measured using this technique, which is frequently employed to verify people’s identities through ID verification services.
Gesture recognition is a technology that reads and interprets hand gestures as orders using sensors. In the VR, AR, and XR industries, this capacity enables occupants to communicate in the virtual world.
To achieve maximum transmission in the desired wavelength range, optical filters are essential. The transition between the high transmission pass area and the immediately following deep blocking region is frequently required to be unusually sharp in order to properly choose only the right wavelength for detection.
Nowadays, almost everyone is familiar with camera, some of us even take photography as a hobby. What is unsaid here is that key parts that made up a camera.
An essential tool for optical designers to reduce unwanted reflections and ghost images inside the camera optics is the application of anti-reflective and black absorber coatings. Thin-film deposition on surfaces inside the optical path that cause unwanted reflections, including camera cover glasses, lenses, or other surfaces, is done to improve the performance of camera modules.
Bedside patient monitoring systems and distant patient monitoring systems are the two main categories of patient monitoring systems. From locations outside than a hospital or clinic, they enable healthcare professionals to track, document, and assess the acute or chronic ailments of their patients. They enable the practitioner to have a real-time understanding of the patient’s disease state and take preventative clinical actions.
To gather the health information, each of these devices uses optical filters, dual-band optical filters, or three band optical filters.
The LBS (Laser Beam Scanning) Display system generates a picture for MR and AR applications by modulating RGB laser beams at each pixel while scanning them onto MEMS mirrors.
LBS display engines must have components like red, green, and blue laser diodes, MEMS-based rapid scanning micromirrors, and micro-optic parts like collimator lenses, beam combiners, and beam homogenizers.
In order to create a virtual image in the viewer’s field of vision, near-eye displays (NEDs) project images directly into their eyes. In comparison to the tiny display panel and optics that were utilized to build it, the image appears distant and larger.
Almost any consumer device can incorporate a projection display thanks to today’s small form factors. There are built-in sensors in consumer electronics, home appliances, video games, toys, and even something as simple as a lamp. To meet the necessary spectrum performance and component size criteria, refined thin-film components are essential.
