Area of Science:

  • Optics
  • Computational Imaging
  • Photonics

Background:

  • Computational ghost imaging (CGI) uses Spatial Light Modulators (SLMs) for structured illumination and information encoding.
  • Current CGI imaging speed is limited by SLM modulation frequency, hindering practical use.

Purpose of the Study:

  • To overcome the speed limitations of conventional CGI.
  • To enhance the modulation frequency of CGI systems.

Main Methods:

  • Proposed a novel approach trading SLM spatial resolution for modulation frequency multiplication.
  • Implemented a proof-of-principle setup using a pair of galvanic mirrors sweeping across a high-resolution SLM.

Main Results:

  • Achieved ghost imaging at 42 Hz with 80x80 pixel resolution.
