Detailed Description
Practical implementation of high quality, high resolution imaging devices is challenging. These challenges are due in part to the expense associated with manufacturing ultra-large area image sensors. For example, a large astronomical telescope with a focal plane of 3.2 giga pixels, using 189,4K by 4K 10 μm pixel CCDs and a field of view of 9.6 degrees at a planar image plane of 640mm, is expected to occupy 8 cubic meters of space, at a cost of about $ 1.05 billion.
Another challenge is related to the aberration scaling of large image plane lenses. That is, lens aberrations scale with size such that a lens system with a diffraction limit at, for example, 10mm focal length (e.g., a Cuk triplet lens) will fail due to aberrations when configured to operate at 100mm focal length.
One approach for producing very high resolution (e.g., gigapixel) imagers is to utilize a multiple micro-camera array configuration in which stitched images can be acquired by a large number of independent cameras. In particular, such a micro-camera array may be arranged to comprise n independent diffraction limited cameras, each camera having a focal plane with S pixels. Each camera may be configured as part of a cylindrical package, where the diameter of the cylinder is the input aperture of the camera, and each camera may generate a separate sample image of the field. In such a micro-camera array, in order to acquire high resolution images, the field of view of each individual camera should have minimal overlap with adjacent cameras. To be able to capture higher resolution images using such a micro-camera system, the focal length of the individual cameras must be increased, thereby increasing the physical volume, weight, and overall cost of the camera array. These costs are prohibitively high for practical implementations of very high resolution imagers (e.g., where images in the range of several gigapixels are required).
To reduce the cost and size associated with a microphotograph array, some systems use a "multi-scale" lens design that includes a common primary optic and then multiple secondary optics. In such a multi-scale system, the primary optics may be curved to minimize aberrations, and the secondary lenses may each be designed to correct off-axis aberrations of the primary lens at the associated field angle. Multi-scale imagers typically produce segmented image planes with overlapping images that can be digitally processed and joined together to produce a single large image. However, such a split image plane does not require a large-scale planar focal plane array, and is therefore advantageous for constructing a high-resolution imager having a small size. In addition, such multi-scale configurations provide better aberration scaling (scaling of aberrations) for low-f iotaeld gigapixel imagers.
However, practical implementation of such multi-scale imagers remains challenging because the fabrication of the free-form (non-rotationally symmetric) aspheric components associated with the secondary optics is not straightforward. Furthermore, the lenses in the secondary portion (i.e., the free-form optics without an axis of symmetry) must be separately manufactured and positioned in three-dimensional space with high precision to correct for the aberrations associated with each field angle. In this way, each image plane may be oriented at a different scale or angle. These and other drawbacks of multi-scale lens designs make it difficult to produce cost-effective imaging systems that can be physically scaled to gigapixel resolution.
The disclosed embodiments relate to methods, apparatus and systems that are capable of producing extremely high resolution images while utilizing optical components that can be manufactured and implemented feasibly within a compact imaging system. Such imaging systems may be manufactured, at least in part, through the use of primary optics configured to produce the same off-axis aberrations for all angles of view. The primary optics providing the common aperture are radially symmetric and constitute a panoramic 360 degree lens. That is, the primary optic includes one or more surfaces adapted to form a symmetrical arrangement about a common origin. It should be noted that the term lens is used herein to include a single lens (or simple lens) as well as a compound lens that includes more than one optical element. In some embodiments, the panoramic 360 degree lens is comprised of one or more spherical or hemispherical portions having a common center of curvature. This panoramic 360 degree configuration provides a curved image plane and produces the same or nearly the same aberrations at each field angle. It should be noted that the terms spherical and hemispherical are used to express surfaces or portions that are substantially spherical or hemispherical. For example, the geometry of such surfaces or portions may deviate from a perfect sphere or hemisphere due to manufacturing limitations.
The high resolution imager of the disclosed embodiments also includes a secondary optic configured to correct for residual on-axis aberrations of the panoramic 360 degree primary optic at each field angle that is the same or nearly the same. Because the aberrations are on-axis, the secondary optic can be constructed using rotationally symmetric components (e.g., spheres) rather than free-form optics as used in other multi-scale designs. The use of a rotationally symmetric sphere in the secondary optic allows for the use of convenient manufacturing processes, e.g., some mature commercial manufacturing processes, and facilitates the construction of imagers using simple alignment techniques.
In some embodiments, each sub-component of the secondary optic is limited to fitting within a cone radiating from a common origin of the first optic. In this way, as long as the secondary optic sub-assembly is confined within the cone, adjacent secondary optic sub-assemblies can be added without overlapping the acquired image sub-assembly.
FIG. 1 illustrates a portion of a system for acquiring high resolution images according to an exemplary embodiment. The panoramic 360 degree primary optic 102 includes one or more common spherical optics 104 having a common point of symmetry that, in the exemplary configuration of fig. 1, is centered within the panoramic 360 degree primary optic 102. Fig. 1 also depicts the secondary optic 106 contained within a cone 108 radiating from a common origin of the primary optic 102. An image sensing device or element 110 (e.g., a CCD or CMOS imaging sensor element) captures light collected by the combination of primary and secondary optics at a particular field angle (in the exemplary configuration of fig. 1, only the on-axis conical portion is depicted). In an implementation, a plurality of imaging sensors or elements 110 are provided in an array configuration and placed in a symmetrical arrangement at different locations about a common origin. For example, a plurality of imaging sensors or elements 110 may be placed on a curved surface. Circuitry or a digital processor within signal processing component 112 may be used to process the outputs from multiple imaging sensors or elements 110 and combine the outputs to form a single composite image. This combined process may be performed by software.
In some embodiments, the signal processing component 112 includes at least one processor and/or controller, at least one memory unit in communication with the processor, and at least one communication unit capable of exchanging data and information directly or indirectly with other entities, devices, databases, and networks via communication links. A communication unit may provide wired and/or wireless communication capabilities according to one or more communication protocols and, thus, may include appropriate transmitter/receiver antennas, circuitry, and ports, as well as encoding/decoding capabilities as needed to properly transmit and/or receive data and other information.
Fig. 2 shows the rest of the system shown in fig. 1. In particular, the central secondary optic 106 is depicted with two adjacent (and physically non-overlapping) secondary optic subcomponents 208, 210 and +60 degree and-60 degree secondary optic subcomponents 212, 214. Other secondary optical sub-assemblies (i.e., sub-imagers) may be added as needed to acquire an image of a given desired field of view. The optical design of the secondary optics should preferably provide overlapping fields of view so that images acquired by adjacent secondary optical paths can be combined to provide a seamless composite image. Such combination may be implemented, at least in part, using signal processing components 112. In the exemplary configuration of FIG. 2, all of the secondary optic sub-assemblies may be substantially similar to each other (and to the central secondary optic sub-assembly 106), having substantially similar focal planes. Thus, the high resolution imaging system of fig. 2 can be mass produced at a lower cost than the multi-stage imagers discussed above, and can be assembled relatively easily due to its loose alignment tolerances. It should be noted that the plurality of secondary optical sub-assemblies have been described as being substantially similar to one another. Such defects are characterized by optical materials, variability in the manufacturing process, and other sources of variation that are present in most, if not all, actual manufacturing and assembly processes.
Fig. 3 illustrates a panoramic 360 degree primary optic according to an exemplary embodiment. The exemplary panoramic 360 degree primary optic of fig. 3 includes 5 elements 302, 304, 306, 308, 310 with a curved focal plane 312. In one exemplary embodiment, the exemplary panoramic 360 degree primary optic of fig. 3 has a focal ratio of 3, an effective focal length of 223mm, a full field of view of 100 degrees, and a length of 317 mm. The total length L is 339 mm. In one exemplary embodiment, five elements of the panoramic 360 degree primary optic are composed of the following glass materials: H-LAK4L, N-PK51, PK51A, H-ZLAF68 and KZFSN 5. The exemplary panoramic 360 degree primary optic of fig. 3 is capable of providing images up to 10 gigapixels over a 100 degree field of view.
