“…(1), the achieved resolution, the SBP, and η for both hologram are shown in Figs. 12(a) and 12(b), and the results from two recent papers [7,14] are shown in Table 1 In conclusion, it was found that the result obtained for the maximum resolution matches well with the expected value. Furthermore, the SBP and the η obtained can compete with the results published in recent papers [7,14].…”

“…In addition, there have been exciting research efforts into wide FOV imaging systems, including contact-imaging microscopy [5,6], digital in-line holography [7][8][9], focus-grid scanning illumination [10][11][12], and off-axis holography microscopy [13,14]. All these methods try to break the tie between resolution and FOV by abandoning the conventional microscopy design and shifting away from the use of optics schemes that perform optical image magnification.…”

Abstract:The capability to perform high-resolution, wide field-of-view (FOV) microscopy imaging is highly sought after in biomedical applications. In this paper, we report a wide FOV microscopy system that uses a closed-circuit-television (CCTV) lens for image relay and a flatbed scanner for data acquisition. We show that such an imaging system is capable of capturing a 10 mm × 7.5 mm FOV image with 0.78 µm resolution, resulting in more than 0.5 billion pixels across the entire image. The resolution and field curve of the proposed system were characterized by imaging a USAF resolution target and a hole-array target. To demonstrate its application, 0.5 gigapixel images of histology slides were acquired using this system. 5654-5659 (2008). 14. M. Lee, O. Yaglidere, and A.

“…Synthetic aperture imaging is a super-resolution technique originally developed for radio telescopes [46,47]. The concept has also been adopted in microscopy imaging systems in recent years [51][52][53][54][55][56][57]. The basic idea of this technique is to combine images from a collection of telescopes in the Fourier domain to improve the achievable resolution.…”

Abstract:We report an imaging scheme, termed aperture-scanning Fourier ptychography, for 3D refocusing and super-resolution macroscopic imaging. The reported scheme scans an aperture at the Fourier plane of an optical system and acquires the corresponding intensity images of the object. The acquired images are then synthesized in the frequency domain to recover a high-resolution complex sample wavefront; no phase information is needed in the recovery process. We demonstrate two applications of the reported scheme. In the first example, we use an aperture-scanning Fourier ptychography platform to recover the complex hologram of extended objects. The recovered hologram is then digitally propagated into different planes along the optical axis to examine the 3D structure of the object. We also demonstrate a reconstruction resolution better than the detector pixel limit (i.e., pixel super-resolution). In the second example, we develop a camera-scanning Fourier ptychography platform for super-resolution macroscopic imaging. By simply scanning the camera over different positions, we bypass the diffraction limit of the photographic lens and recover a super-resolution image of an object placed at the far field. This platform's maximum achievable resolution is ultimately determined by the camera's traveling range, not the aperture size of the lens. The FP scheme reported in this work may find applications in 3D object tracking, synthetic aperture imaging, remote sensing, and optical/electron/X-ray microscopy.
