we demonstrate tissue imaging at a wavelength of 1.3 µm with ~3.2 µm lateral resolution, maintained nearly intact over a 1.25 mm depth of focus, with no additional acquisition or computational burden. This method, termed bijective illumination collection imaging, is general and mig...
With the development of computational imaging, coded reconstruction spectrometers are expected to address the limitations of spatial-spectral mapping type SSI techniques, which are constrained by the number of detector pixels. These systems employ innovative optical devices, such as coded masks, ...
Using meta-imagers composed of a meta-lens and a complex-amplitude meta-modulator, all-optical convolutional processing that arbitrarily reshapes the point spread function of an optical system can now be implemented. Image processing is a technology that transforms an image into the desired form by...
computational imagingMetasurface-based hyperspectral imaging has profoundly impacted the field, with its easy integration and miniaturization advantages. Notably, metallic metasurfaces have been a research subject in sensing and imaging due to their strong capability of restraining light and supporting high-...
In this paper, we present a 3-bit terahertz metasurface unit based on encoded structured light for realizing a multifunctional and reconfigurable terahertz metasurface with optically controlled multi-order vortex beam and holographic imaging. Coded structured light is a common computational light source. ...
However, increasing the number of snapshots also lengthens the sampling time of the system, which increases the computational cost. Figure 7. DOA estimation performance for the different numbers of snapshots. 4.2.3. Performance Analysis for the Number of Harmonics In the third part, the impact ...

structure. In optical communication and imaging systems, a uniform spectral response in optical devices is imperative, as it eliminates the need for additional power distribution or filters. In the realm of optical communication, Airy beams have yet to showcase their full potential, while orbital ...
