摘要： An optical finger navigation device includes an image sensor, a tracking surface, and an optical element. The image sensor generates an image representative of light detected at a pixel array that has a pixel pitch which at least partially defines a surface area of a pixel. The tracking surface is approximately parallel to the image sensor. A first distance between and substantially orthogonal to planes of the tracking surface and the image sensor is insufficient under a set of illumination constraints to produce at the image sensor a speckle size above a threshold. The threshold is approximately one order of magnitude less than the pixel pitch. The optical element is interposed between the tracking surface and the image sensor. The optical element includes at least one optical redirection surface to redirect light along an optical path of a second distance between the tracking surface and the image sensor.

摘要： A system for optical navigation includes a light source and an imaging system. The light source illuminates a navigation surface. The navigation surface reflects light from the light source. The imaging system is located approximately within a path of the reflected light. The imaging system includes a lens, a mask, and an image sensor. The lens receives reflected light from the navigation surface. The lens focuses a specular portion of the reflected light to a focus region. The mask is located at approximately the focus region. The mask filters out substantially all of the specular portion of the reflected light and passes at least some of a scatter portion of the reflected light outside of the focus region. The image sensor generates a navigation signal based on the scattered portion of the light that passes outside the focus region and is incident on the image sensor.

摘要： Disclosed are various embodiments of a navigation input device, and methods, systems and components corresponding thereto. According to some embodiments, the navigation input device has a large depth of field associated therewith and employs time- and/or frequency-domain processing algorithms and techniques. The device is capable of providing accurate and reliable information regarding the (X,Y) position of the device on a navigation surface as it is moved laterally thereatop and thereacross, notwithstanding changes in a vertical position of the device that occur during navigation and that do not exceed the depth of field of an imaging lens incorporated therein. According to one embodiment, the navigation input device is a writing instrument that does not require the use of an underlying touch screen, touch pad or active backplane to accurately and reliably record successive (X,Y) positions of the writing device as it is moved across and atop an underlying writing medium such as paper, a pad or a display.

摘要： An optical finger navigation device includes a navigation cover. The navigation cover includes a tracking surface and an illumination surface. The tracking surface exhibits a first light reflection characteristic in a presence of a navigation object at the tracking surface and a second light reflection characteristic in an absence of the navigation object at the tracking surface. A light source generates illumination directed toward the illumination surface of the navigation cover. A redirection structure is interposed between the light source and the illumination surface of the navigation cover. A reflection surface of the first redirection structure is approximately facing the illumination surface of the navigation cover. An illumination surface of the redirection structure is approximately facing the light source. The redirection structure defines at least one hole therethrough to pass light generated by the light source toward the illumination surface of the navigation cover.
