“…In addition, these filters are broadband to increase their SNRs. The filtered light is then shaped by a DMD-based band-limited projector [227]. As shown in figure 10(c), the light illuminates the DMD, on which a binary pattern is loaded.…”

Single-shot coded-aperture optical imaging physically captures a code-aperture-modulated optical signal in one exposure and then recovers the scene via computational image reconstruction. Recent years have witnessed dazzling advances in various modalities in this hybrid imaging scheme in concomitant technical improvement and widespread applications in physical, chemical and biological sciences. This review comprehensively surveys state-of-the-art single-shot coded-aperture optical imaging. Based on the detected photon tags, this field is divided into six categories: planar imaging, depth imaging, light-field imaging, temporal imaging, spectral imaging, and polarization imaging. In each category, we start with a general description of the available techniques and design principles, then provide two representative examples of active-encoding and passive-encoding approaches, with a particular emphasis on their methodology and applications as well as their advantages and challenges. Finally, we envision prospects for further technical advancement in this field.

“…[30] Second, most CUP systems use a digital micromirror device (DMD) to spatially encode the dynamic event. As a programmable binary-amplitude spatial light modulator, [31,32] the DMD consists of up to several millions of individually addressable micromirrors, each of which has a +12°or -12°tilt angle with respect to the device's surface normal. As a result, the DMD is often required to be placed in the Littrow configuration in CUP systems to retro-reflect the incident light.…”

Compressed ultrafast photography (CUP) is an emerging potent technique that allows imaging a nonrepeatable or difficult-to-produce transient event in a single shot. Despite many recent advances, existing CUP techniques operate only at visible and near-infrared wavelengths. In addition, spatial encoding via a digital micromirror device (DMD) in CUP systems often limits its field of view and imaging speeds. Finally, conventional reconstruction algorithms have limited control of the reconstruction process to further improve the image quality in the recovered (x, y, t) datacubes of the scene. To overcome these limitations, this article reports a single-shot UV-CUP that exhibits a sequence depth of up to 1500 frames with a size of 1750 × 500 (x, y) pixels at an imaging speed of 0.5 trillion frames per second. A patterned photocathode is integrated into a streak camera, which overcomes the previous restrictions in DMD-based spatial encoding and improves the system's compactness. Meanwhile, the plug-and-play alternating direction method of multipliers algorithm is implemented to CUP's image reconstruction to enhance reconstructed image quality. UV-CUP's single-shot ultrafast imaging ability is demonstrated by recording UV pulses transmitting through various spatial patterns. UV-CUP is expected to find many applications in both fundamental and applied science.

“…Compared to liquid crystal SLM, the overall efficiency of the DMD especially when used for phase modulation is relatively low, about 5% in terms of the incident laser power. In fact, the DMD can also work in a pure amplitude fashion 28 with much higher efficiency, but then the galvanometers are required for the dithering and scanning as the conventional systems. Actually, one can increase the incident laser power in practical imaging experiments, which does not affect the imaging performance of the light sheet.…”

Lattice light sheet microscopy is uniquely positioned in biomedical imaging modalities due to its superior performance in temporal-spatial resolution and low phototoxicity. However, the imaging system is commonly complicated because producing lattice light sheets involves mechanical scanning and precise alignment. In this Letter, we present an experimental scheme for motionless synthesis and scanning of lattice light sheets using a single digital micromirror device. By fully exploiting its ability of complex amplitude modulation and fast switching, single-shot construction of a uniform lattice light sheet can be achieved by digital dithering. In particular, fast scanning of the lattice light sheet in the depth direction is also realized without any mechanical motion. As a proof of concept, various lattice light sheets are generated and characterized in the experiments. Our work is expected to benefit the development of a compact and low-price lattice light-sheet microscope for biomedical imaging.
