Background:

Traditional imaging systems face limitations in acquiring high-dimensional data efficiently.
Multiplexing and spatial encoding offer potential for overcoming data acquisition bottlenecks.

Purpose of the Study:

To develop and validate a generalized theoretical framework for multiplexed spatially encoded imaging.
To demonstrate the system's capability in acquiring multi-channel data exceeding detector element count.

Main Methods:

Development of a theoretical framework for spatially encoding and multiplexing object channels.
Implementation of a numerical estimation algorithm with sparsity constraints for demultiplexing.
Adaptation of the two-step iterative shrinkage/thresholding algorithm with total variation for reconstruction.

Main Results:

Simulations and experimental results confirm the theoretical framework.
Successful acquisition and reconstruction of multi-channel data, even when object elements exceed captured data points.
Demonstrated wide field-of-view and spectral imaging capabilities with sparse objects.

Conclusions:

The proposed framework enables efficient multi-channel data acquisition using multiplexing and spatial encoding.
The system effectively solves underdetermined reconstruction problems inherent in compressed sensing.
This approach offers a viable solution for single-shot, multi-channel data acquisition with detector arrays.
