摘要： Disclosed are various embodiments of a holographic based optical touchscreen and methods of configuring such devices. In certain embodiments, a touchscreen assembly can include a holographic layer configured to receive incident light and turn it into a selected direction to be transmitted through a light guide. The holographic layer can be configured to accept incident light within an acceptance range and so that the selected direction is within some range of directions so as to allow determination of incidence location based on detection of the turned light. A light source can be provided so that light from the source scatters from an object such as a fingertip near the holographic layer and becomes the incident light. Thus the determined incidence location can represent presence of the fingertip at or near the incidence location, thereby providing touchscreen functionality. Non-limiting examples of design considerations and variations are disclosed.

摘要： A device and method for emitting light with increased brightness utilizes a lamp having a diffractive grating pattern. The diffractive grating pattern diffracts incident light that originates from a light source toward a light output region of the lamp. The diffraction of the incident light causes more of the light to impinge the light output region of the lamp at desired angles. This reduces the angular distribution of the light emitted from the light output region as output light. The reduction in angular distribution of emitted light results in an increased brightness of the device.

摘要： A color image sensor has imaging elements each structured to form, at an image plane, an image of a subject having a respective magnification. Ones of the imaging elements forming respective ones of the images with the same magnification in light of mutually different colors constitute a set characterized by the magnification of the images. The sets having mutually-different magnifications. The color image sensor additionally has a light sensor located in the image plane and comprising a region of sensor elements disposed opposite each of the imaging elements. The regions of sensor elements opposite each of the sets of imaging elements are operable to generate, in response to light incident thereon, a respective color image signal representing the image of the subject at the respective magnification.
