报告摘要：

Optical instruments are usually judged by how much information they can separate, resolve and measure. Conventional systems achieve this through carefully arranged optical components, including lenses, filters, gratings and scanning elements. Miniaturised light-field detectors and spectrometers challenge this model. By replacing part of the optical complexity with engineered materials, device physics and computational reconstruction, they offer a route towards compact instruments that can measure rich optical information outside the controlled environment of the laboratory. In this talk, I will discuss this emerging design philosophy for miniaturised computational light detection, with a focus on the visible regime. The central idea is to use constrained hardware not as a limitation, but as a physical encoder of optical information. Computation is then used to reconstruct the underlying spectral, spatial or other light-field content from the resulting measurements. This approach shifts the emphasis from simply shrinking conventional instruments to co-designing the material response, device architecture and reconstruction algorithm. In doing so, it points towards optical systems that are not only smaller, but also more manufacturable, task-specific and suitable for real-world sensing and portable spectroscopy.
