“…This approach has been pushed further using a plenoptic camera [11]. Finally, combining a prism array with common cameras has been proposed to double [6] or quadruple [27] the FOV of the main-lens. In [24], prisms and mirrors are combined for stereo capture out of a single lens camera.…”

In this paper we study the light field sampling produced by ideal plenoptic sensors, an emerging technology providing new optical capabilities. In particular, we leverage its potential with a new optical design that couples a pyramid lens with an ideal plenoptic sensor. The main advantage is that it extends the field-of-view (FOV) of a main-lens without changing its focal length. To evince the utility of the proposed design we have performed different experiments. First, we demonstrate on simulated synthetic images, considering ideal and real lenses, that our optical design effectively doubles the FOV. Then, we show its feasibility with two different prototypes using plenoptic cameras on the market with very different plenoptic samplings, namely a Raytrix R5 and a Canon 5D MarkIV. Arguably, future cameras with ideal plenoptic sensors will be able to be coupled with pyramid lenses to extend its inherent FOV in a single snapshot.

“…This has been investigated in designs that use multiple lenses to form images on a single FPA, 1 a cascade of beam splitting elements to divert multiple FoVs into a single lens, [2][3][4][5] and by placing an interleaved array of subaperture microprisms in front of a single lens. 6,7 In a recent paper, 8 we presented a new optical design architecture based on a division of aperture technique that divides the pupil area of a single lens into a number of independent imaging channels. As discussed in that paper, this method offers advantages over prior approaches through its flexibility to individually direct and encode the optical channels, and it yields a significant volume advantage in systems with a high degree of multiplexing at a cost of an optical resolution loss due to the divided aperture.…”

Shift-encoded optically multiplexed imaging

Abstract. In a multiplexed image, multiple fields-of-view (FoVs) are superimposed onto a common focal plane. The attendant gain in sensor FoV provides a new degree of freedom in the design of an imaging system, allowing for performance tradeoffs not available in traditional optical designs. We explore design choices relating to a shift-encoded optically multiplexed imaging system and discuss their performance implications. Unlike in a traditional imaging system, a single multiplexed image has a fundamental ambiguity regarding the location of objects in the image. We present a system that can shift each FoV independently to break this ambiguity and compare it to other potential disambiguation techniques. We then discuss the optical, mechanical, and encoding design choices of a shift-encoding midwave infrared imaging system that multiplexes six 15 × 15 deg FoVs onto a single one megapixel focal plane. Using this sensor, we demonstrate a computationally demultiplexed wide FoV video.

“…Due to the use of multiple cameras, this inevitably increases the system cost as well as the spatial area of the application; (2) the second group creates two or more viewpoints using a single camera equipped with mirrors, 3,4 prism, 5,6 or other optical equipment.

This paper combines the prism and single camera and puts forward a method of stereo imaging with low cost. First of all, according to the principle of geometrical optics, we can deduce the relationship between the prism single-camera system and dual-camera system, and according to the principle of binocular vision we can deduce the relationship between binoculars and dual camera. Thus we can establish the relationship between the prism single-camera system and binoculars and get the positional relation of prism, camera, and object with the best effect of stereo display. Finally, using the active shutter stereo glasses of NVIDIA Company, we can realize the three-dimensional (3-D) display of the object. The experimental results show that the proposed approach can make use of the prism single-camera system to simulate the various observation manners of eyes. The stereo imaging system, which is designed by the method proposed by this paper, can restore the 3-D shape of the object being photographed factually.2 Literature Review Compared to the multicamera stereo imaging system, the prism-based single-camera system has great advantages including cost-effectiveness, compactness, low computational
