摘要： Devices and methods for multiplexed imaging are provided. In one embodiment, an imaging device can simultaneously direct light of a same spectrum from each of a plurality of image channels onto an image sensor to create a multiplexed image on the sensor. Each image channel can collect light from different portions of an extended field of view or from the same portion with different perspectives. The device can also include one or more encoders to encode light from the channels prior to detection. The devices and methods described herein can also include disambiguating a captured multiplexed image to create images for each of the plurality of image channels. Disambiguated images can cover the extended field of view at a high spatial resolution despite using only a single small format image sensor, or can produce stereo or 3D images having the full resolution of the sensor.

摘要： System and method for utilizing two prisms spatially separated is provided. The two prisms spatially separated allows the two prisms typically found in a TIR optical relay system to be spatially separated. In an embodiment, one or more optical relay lenses are interposed between the two prisms. The prism positioned on the object side may be integrated into one or more of the optical relay lenses, thereby further simplifying the optical relay design. In another embodiment, the one or more optical relay lenses may have an optical axis that is offset from the optical axis of incoming light to cause a pupil shift. An aspherical lens may be included to correct for the pupil shift and create a more uniform illumination image.

摘要： Apparatus and methods are disclosed for transforming a laser beam to a polarized shaped beam in, for example, a frequency converted laser system. In one embodiment, an anamorphic optical system includes a first prism and a second prism that can be configured to form a Brewster telescope, the first prism and second prism each having an input surface and an exit surface, and wherein at least one surface of the input or exit surfaces are coated with a polarization selective coating.

摘要： In an image-forming optical system in which an astigmatism may occur, an astigmatism correcting element disposed between an image-forming lens (20) and an image-forming surface (12) in order to correct the astigmatism is constructed such that it can correct the T image surface toward both plus and minus directions with respect to the S image surface, while easily correcting the astigmatism even when there is fluctuation in the generated astigmatism. The astigmatism correcting element comprises a prism unit (22) in which a pair of wedge-like prisms (22a, 22b) having an identical apex angle are oppositely placed in reverse to each other with a predetermined air space (d) therebetween. Also, this prism unit (22) is disposed such that its optical axis (X1) can be tilted with respect to a main ray (X2) of a bundle of rays subjected to astigmatism correction. The angle of inclination of the optical axis (X1) of the prism unit (22) may be appropriately set so as to nullify the astigmatism of the bundle of rays subjected to astigmatism correction or to intentionally provide a desired astigmatism in this bundle of rays, regardless of whether the main ray (X2) in the bundle of rays subjected to astigmatism correction is on the optical axis (X0) of the image-forming optical system or not.

摘要： An optical head device having an optical system provided with at least a light source, a shaping prism, a diffracting element and a photodetector. The light source emits light whose cross-sectional intensity distribution has an elliptic shape. The shaping prism directs the light to a recording medium after shaping the intensity distribution thereof into a circular shape. The diffracting element has diffracting regions formed by at least one division line parallel to a reference direction. The light reflected from the recording medium forms an elliptic bright portion on the diffracting element. The photodetector is divided by a plurality of division lines, at least one of which is parallel to the reference direction. When there is no focus error, the diffracting element diffracts the reflected light so as to converge it on the division line substantially parallel to the reference direction in the photodetector. For example, when the shaping prism is adapted to shape the elliptic intensity distribution with respect to its major axis direction, the optical system is arranged so that the major axis of the bright portion coincides with the division line of the diffracting element. Thus, it is possible to obtain preferable focusing control.

摘要： An optical pickup device having an optical system provided with at least a light source, a shaping prism, a diffracting element and a photodetector. The light source projects light whose intensity distribution has an elliptical shape in its cross section orthogonal to the optical axis. The shaping prism directs the light to a recording medium after shaping the intensity distribution thereof into a circular shape. The diffracting element has diffraction regions formed by at least one division line substantially parallel to a reference direction. The light reflected from the recording medium forms an elliptical bright portion on the diffracting element. The photodetector is divided by a plurality of division lines, at least one of which is substantially parallel to the reference direction. The diffracting element diffracts the reflected light so as to converge it on the photodetector. Have, a hypothetical line extending from a projecting point of the light source through the center of a light-receiving face of the photodetector is also set to be parallel to the reference direction. For example, when the shaping prism is to shape the intensity distribution having the elliptical shape with respect to its minor axis direction, the optical system is arranged so that the minor axis of the bright portion is parallel to the division line of the diffracting element. Thus, it is possible to always obtain an accurate focusing control signal.

摘要： Between an image intensifier (II) having a circular radiation exit surface (II2) and an image sensor in the form of a solid state sensor (CTD) with a rectangular picture pick-up surface (PP) there is arranged an optical coupling system (OP) for producing an ellipsoidal picture (EL) of the circular radiation exit surface (II2) within or at least partly around the rectangular picture pick-up surface (PP). A signal correction device (GEN, CTD or PROC, respectively) is provided for compensating the adaptation of the optical coupling system, whilst the sensor may form part of said device (GEN, CTD), said compensation being effected by adapting the clock pulse frequency so that the corrected picture signal produces the image in a circular surface (DIS) on a screen (MIS) of a picture display device (MON).
