    摘要: An optical switching device (100, 200, 300), comprising: a substrate (103, 203, 303); a layer (102, 202, 302) of an active material disposed on the substrate (103, 203, 303), the active material being either a phase change material or a material which, by changing its stoichiometry, its optical properties change, wherein the active material is configured to change upon application of an external stimulus between a crystalline phase having a first refractive index and an amorphous phase having a second refractive index; and a layer (101, 201, 301) of a transparent material disposed on the layer (102, 202, 302) of active material, wherein the layer of a transparent material is a prism (101, 201, 301) defining an angle α selected such that, when a linearly polarized plane wave reaches an entrance face of the prism (101, 201, 301) and radiation is refracted and travels within the prism (101, 201, 301) until it reaches the surface of the layer (102, 202, 302) of active material, the Brewster condition is met for one of the two phases, of the active material, so that when the active material is in the phase for which the Brewster condition is met, radiation is not reflected at the interface between the prism (101, 201, 301) and the layer (102, 202, 302) of active material, while when the active material is in the other phase, radiation is reflected at said interface and leaves the optical switching device (100, 200, 300) when it reaches an output face of the prism (101, 201, 301), thus controlling the switching mode of the optical switching device (100, 200, 300) through the presence or absence of reflected light at said interface.

    摘要: A conventional optical switching engine has difficulty in producing a universal multiport switching engine being capable of (i) programmatically changing regions to be switched, (ii) generating no wavelength dependent loss, (iii) having a small Walk-off, and (iv) being usable for small to large light beams. Produced is a light beam deflecting element in which a polarization grating is fitted in parallel on an N×M transmissive birefringence modulator formed such that a transmissive variable half-wavelength liquid crystal plate is divided into rectangular extreme small pixels, and many N and M pixels thus obtained are respectively arranged in X and Y axes directions in a matrix form, the polarization grating being a grating in which a period Λ changes in an X' axis direction (direction to which a birefringence axis rotates) in accordance with a wavelength width of light.

    摘要: A scanner (300) for scanning an item (302) positioned in a scan volume (304) can include: an electronically switchable mirror (306) configured to switch between a reflective state and a transmissive state, a plurality of mirrors (310, 312), and a camera (314) having a sensor. In a method for scanning the item, the scanner (300) can repeatedly: switch the switchable mirror (306) from the reflective state to the transmissive state, image a first field of view (316) of the item (302) onto the sensor with light that reflects from at least one mirror (310) and transmits through the switchable mirror (306), switch the switchable mirror (306) from the transmissive state to the reflective state, and image a second field of view (318) of the item (302) onto the sensor with light that reflects from at least one mirror (312) and reflects from the switchable mirror (306). In some examples, the scanner (300) can synchronize the switching of the switchable mirror (306) to a frame rate of the sensor.
