Computational ghost imaging using a field-programmable gate array
This work addresses a bottleneck in single-pixel imaging for applications requiring fast processing, though it is incremental as it optimizes an existing method.
The paper tackled the problem of long calculation times in computational ghost imaging by designing a dedicated circuit using a field-programmable gate array, achieving image reconstruction at a frame rate of 300 Hz.
Computational ghost imaging is a promising technique for single-pixel imaging because it is robust to disturbance and can be operated over broad wavelength bands, unlike common cameras. However, one disadvantage of this method is that it has a long calculation time for image reconstruction. In this paper, we have designed a dedicated calculation circuit that accelerated the process of computational ghost imaging. We implemented this circuit by using a field-programmable gate array, which reduced the calculation time for the circuit compared to a CPU. The dedicated circuit reconstructs images at a frame rate of 300 Hz.
