A light irradiation apparatus includes a light source, a dispersive element, a spatial light modulator, and a focusing element. The dispersive element disperses pulsed light output from the light source and outputs the light. The dispersive element includes, for example. The spatial light modulator modulates a phase spectrum or an intensity spectrum of the light output from the dispersive element and outputs the light. The focusing element receives the light output from the spatial light modulator in a dispersing state, and focuses the light on a common region (focusing region) in a surface or an inside of an object.

A one-way glass based on the persistence of vision of human eyes includes a double glazing or a single glazing. The double glazing includes a switchable glass with electrically controllable and adjustable light transmittance, and a luminous glass that is electronically controlled to emit light. The luminous glass is a transparent glass. The switchable glass and the luminous glass are controlled by pulse signals of a pulse controller.

The invention is notably directed to a transflective display device. The device comprises a set of pixels, wherein each of the pixels comprises a portion of bi-stable, phase change material, hereafter a PCM portion, having at least two reversibly switchable states, in which it has two different values of refractive index and/or optical absorption. The device further comprises one or more spacers, optically transmissive, and extending under PCM portions of the set of pixels. One or more reflectors extend under the one or more spacers. An energization structure is in thermal or electrical communication with the PCM portions, via the one or more spacers. Moreover, a display controller is configured to selectively energize, via the energization structure, PCM portions of the pixels, so as to reversibly switch a state of a PCM portion of any of the pixels from one of its reversibly switchable states to the other. A backlight unit is furthermore configured, in the device, to allow illumination of the PCM portions through the one or more spacers. The backlight unit is controlled by a backlight unit controller, which is configured for modulating one or more physical properties of light emitted from the backlight unit. The invention is further directed to related devices and methods of operation.
