A beam of LED light traveling at an angle of 45 degrees from straight ahead is at a diagonal, which is the hypotenuse of that 45-degree angle. That is, the light must travel 1.414 farther to reach its ...

Following research at Sheffield-based LED packaging firm Litecool, narrow beam angles from LED packages without secondary optics or reflectors look closer. The proof-of-concept device produced a beam ...

Inversely, we can compute the beam angle as a function of phase shift. ... the maximum achievable steering angle is always less than 90°. This is due to the element factor and other degradations at ...

A high-efficiency beam steering angle expander consisting of two liquid crystal polymeric diffractive optical elements is demonstrated. For an LiDAR (light detection and ranging) operating at 905 ...

Beam steering is an important factor in LIDAR, microscopy, telescopes, and optical wireless communications. In each of these areas, there is a need for a large sensing range using components with ...

The prototype radiotherapy system combines a fixed vertical radiation beam with horizontal patient rotation. (Courtesy: Paul Liu) Radiation therapy plays a fundamental role in cancer treatment, but ...
