A spectrally shearing optical relay system, said relay system being comprised of two halves disposed symmetrically about an aperture stop S, wherein each half comprises a plurality of rotationally symmetric optical elements forming an objective and a com-pound prism comprised of a plurality of dispersing prisms. The compound prisms are located between the objectives and the aperture stop. An imaging device with such an optical relay system is also proposed.

A dual sensor camera that uses two aligned sensors each having a separate lens of different focal length but the same f-number. The wider FOV image from one sensor is combined with the narrower FOV image from the other sensor to form a combined image. Up-sampling of the wide FOV image and down-sampling of the narrow FOV image is performed. The longer focal length lens may have certain aberrations introduced so that Extended Depth of Field (EDoF) processing can be used to give the narrow FOV image approximately the same depth of field as the wide FOV image so that a noticeable difference in depth of field is not see in the combined image.

An optical navigation device that can sense the movement of an object, such as a user's finger, so that the movement can control a feature of a consumer digital device such as a cursor on a display screen. The device includes a substrate to which an LED, reflector, and image sensor are attached. Light from the LED is directed by the elliptical reflector toward and through a window that is transparent to the light from the LED and then is reflected off of the user's finger back through the window, through a lens, and onto the image sensor. The reflector is positioned to direct light toward the window at an oblique angle, in the range of 65 to 70 degrees from an angle normal to the window. Further, the reflector is curved to gather light across a large solid angle in the vicinity of the LED. The curved shape of the reflector may be a portion of an ellipsoid and the LED may be located at one of the foci of the ellipsoid, with the window located at the other foci of the ellipsoid.

A dual focal length optical system includes a first optical system and a second optical system. The first optical system is positioned along an optical axis and includes an optical structure having an object side surface and an image side surface. The object side surface and the image side surface include a refractive surface portion and a reflective surface portion. The first optical system has a focal length. The second optical system is positioned on the same optical axis and has a focal length. The focal length of the first optical system is longer than the focal length of the second optical system.

Imaging systems and methods for calibrating imaging systems are provided. The imaging system has a body, a scene image capture system that captures images using a taking lens system that can be set to a plurality of different focus distances, and a rangefinder that is capable of determining a distance between the imaging system and at least one portion of a field of view of the taking lens system. The method comprises: automatically capturing a first calibration image of a first field of view through the taking lens system with the taking lens system set to a first focus distance setting; identifying a portion of the first calibration image having a predetermined degree of focus; using the rangefinder to determine a first calibration distance from the imaging device to the identified portion. A focus correlation is determined based upon the first calibration distance and the first focus distance setting.

A dual focal length optical system includes a first optical system and a second optical system. The first optical system is positioned along an optical path and includes an optical structure having an object side surface and an image side surface. The first optical system also includes a first surface of an intermediate reflective element located between the object side surface and the image side surface of the optical structure as viewed along the optical path. The first optical system has a first focal length. The second optical system shares a portion of the same optical path and includes a second surface of the same intermediate reflective element as that of the first optical system. The second optical system has a second focal length. The first focal length of the first optical system is longer than the second focal length of the second optical system.

A dual resolution printer for printing images on an associated print medium includes: a light source providing a light beam and a focusing lens focusing the light beam and creating a converging light beam having at least one beam waist of at least one wavelength at a first beam waist location. The printer also includes an optical unit movable in and out of the converging light beam and having a corresponding first and second position, respectively. This optical unit, in the second position, reimages the beam waist of the converging light beam created by the focusing lens to a different size second beam waist, at a location substantially the same as the first beam waist location.

A printer system for producing color prints includes: (a) three light sources, each generating a light beam of different wavelengths; (b) three modulators, each of the modulators modulating intensity of each of the light beams by image data, to provide three modulated light beams; (c) a beam combiner combining the three modulated light beams into a single light beam; (d) a single set of beam shaping optics shaping this single light beam into a shaped light beam having different vergences and waist locations in the page and line directions, the vergences and the waist locations being substantially the same in each of the three wavelengths; (e) a light deflector deflecting the shaped light beam to provide a deflected beam, and performing a scanning function; (f) an f-.theta. lens focusing the deflected light beam onto an associated image surface.
