Spatial modulations testing in a hyperspectral single-pixel microscopy
Original language description
Various modes of spatial modulations in compressive imaging can vastly affect the measurement quality and reduce the number of measurements needed. While there have been experiments focusing on different modulations, usually only a handful have been tested and in varying conditions. We propose a scheme unifying the testing parameters while exploiting our dual hyperspectral compressive microscope to create a range of conditions in one measurement. In it, the influence of light collection from the DMD, including its diffraction, can be considered. With this, we proceeded to test a total of 20 modulations and their modifications. Simulations using the same parameters were conducted with and without added noise. In the experimental setup, all modulations have been tested across three samples and three different resolutions to provide a comprehensive comparison. Individual effects and complications have also been identified, providing tips for modulation testing and deployment.
