AI Technical Summary
Existing fiber optic spectral demodulation modules have limitations in terms of high throughput and high resolution. Physical slits cause light intensity loss and limit resolution, while detector pixel size and pixel binning techniques affect response speed and resolution.
A virtual slit generator is used to eliminate physical slits. Combined with a beam width adjustment module and pixel merging technology, the spot diameter and pixel unit are dynamically adjusted to achieve adjustable resolution and response speed, and an integrated optical path design.
It improves the utilization rate of light flux, reduces light intensity loss, achieves high-resolution spectral demodulation, and adapts to the miniaturization and multi-channel sensing requirements in extreme environments.
