AI Technical Summary
Technical Problem
In existing structured illumination microscope systems, spatial light modulators (SLMs) are expensive, inefficient, and require complex optical and electronic overhead, making it difficult to efficiently modulate the intensity and phase of the illumination beam.
Method used
A phase mask, comprising a light-blocking layer disposed on a substrate, with multiple optical transmission zones and segments of different phase configurations, is used to generate stripe patterns, replacing the SLM device.
Benefits of technology
It enables efficient and low-cost modulation of the intensity and phase of the illumination beam, improving imaging resolution, especially imaging quality in Raman spectroscopy and fluorescence spectroscopy.
