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 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.

Laser displays using phosphor screens emitting visible colored light

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.

Multilayered fluorescent screens for scanning beam display systems

Scanning beam display systems based on scanning light on a fluorescent screen. The screen can include fluorescent materials which emit visible light under excitation of the scanning light to form images with the emitted visible light. Multiple lasers can be used to simultaneously scan multiple laser beams to illuminate the screen for enhanced display brightness. For example, the multiple laser beams can illuminate one screen segment at a time and sequentially scan multiple screen segments to complete a full screen.

Optical designs for scanning beam display systems using fluorescent screens

Scanning beam systems, apparatus and techniques in optical post-objective designs with two beam scanners for display and other applications.

Post-objective scanning beam systems

Multilayered screens with parallel light-emitting stripes for scanning beam display systems. The light-emitting materials may include phosphor materials and non-phosphor materials.

Multilayered screens with light-emitting stripes for scanning beam display systems

An apparatus and a method for acquiring an image of skin topology. The apparatus comprises at least one light source, configured to form a source beam; at least one illuminating diffractive optical element (DOE) disposed in the optical path of the source beam, configured to diffract the source beam, thereby forming an illuminating beam; a skin contact surface, disposed in the optical path of the illuminating beam, configured to at least partially reflect the illuminating beam at regions of the boundary between the skin contact surface and skin that are not in contact with the skin contact surface, thereby forming a reflected beam; at least one imaging diffractive optical element (DOE), disposed in the optical path of the reflected beam, configured to diffract the reflected light beam, thereby forming an image beam; and a sensor array, configured to receive at least a portion of the image beam and thereby to detect the acquired image.
