Fluorescent screens and display systems and devices based on such screens using at least one excitation optical beam to excite one or more fluorescent materials on a screen which emit light to form images. The fluorescent materials may include phosphor materials and non-phosphor materials such as quantum dots. A screen may include a multi-layer dichroic layer.

Display systems having screens with optical fluorescent materials

Scanning beam display systems that scan one servo beam and an excitation beam onto a screen that emits visible light under excitation of the light of the excitation beam and control optical alignment of the excitation beam based on positioning of the servo beam on the screen via a feedback control.

Servo feedback control based on designated scanning servo beam in scanning beam display systems with light-emitting screens

Scanning beam display systems using fluorescent screens and various servo feedback control mechanisms to control display imaging qualities.

Servo-assisted scanning beam display systems using fluorescent screens

Methods and systems for improving imaging quality and power efficiency of scanning beam display systems using fluorescent screens are disclosed. In various embodiments, beam shaping mechanisms for maximizing overlap between the beam cross-section and the florescent element corresponding to each color sub-pixel of the screen, as well as pulse width and timing adjustments, are introduced to reduce imaging noise and improve power efficiency of the display system.

Laser display systems using at least one scanning laser beam to excite one or more fluorescent materials on a screen which emit light to form images. The fluorescent materials may include phosphor materials.

Display screens having optical fluorescent materials

An apparatus for image acquisition of topological features of the surface of skin. The apparatus comprises a waveguide, having an entrance edge and top and bottom surfaces; a light source, configured to direct a light beam at the entrance edge of the waveguide; a skin contact layer, disposed at or near the top surface of the waveguides; a holographic optical element (HOE), disposed at the top or at the bottom surfaces of the waveguide, configured to diffract the light beam incident from the light source to the skin contact layer; a sensor array, configured to detect light reflected from the surface of skin in contact with skin contact layer; and means for compensating for changes in the Bragg matching condition of the HOE due to temperature.
