Simultaneous Spatial, Spectral, and 3D Compressive Imaging via Efficient Fourier Single-Pixel Measurements

Speaker: Mariia Shutova

Single-pixel imaging can capture images using a detector without spatial resolution, which enables imaging in various situations that are challenging or impossible with conventional pixelated detectors. Here we report a compressive single-pixel imaging approach that can simultaneously encode and recover spatial, spectral, and 3D information of the object. We demonstrate an 88% compression ratio for producing a high-quality full-color 3D image. The reported approach provides a solution for information multiplexing in single-pixel imaging settings. It may also generate new insights for developing multi-modality computational imaging systems.

Mid-Infrared (2–8 µm) Laser Sources and Their Applications

Speaker: Anton Shutov

The mid-infrared (mid-IR) spectrum region (2- 8 µm) of the electromagnetic radiation possess a special interest for scientists in many fields: spectroscopy, material processing, medicine and nonlinear optics. However, the lack of powerful, reliable and tunable mid-infrared laser sources has been slowing down the employment of mid-IR in these fields. In this talk I will review the current state of the art mid-IR laser systems and discuss their potential applications, especially in the nonlinear optics experiments.
