Single-pixel spectroscopy via compressive sampling Conference Paper uri icon

abstract

  • Classical conventional spectrometers are typically based on spectral separation (scanning with narrow band spectral filtering); the polychromatic light passes through a band selective filtering element and the transmitted power is meas- ured by an irradiance sensor. By performing this process with multiple and different band pass filters information about the spectral power distribution is acquired. This is commonly is accomplished with various devices and spectral scanning schemes. For example colored and tunable filters can be used to sample the different wavelengths at different times, or dispersive prisms or diffractive gratings can be used to sample the different wavelengths at different angles or locations. Compressed Sensing (CS, also known as compressive sensing or compressive sampling) is a new area of signal processing whose goal is to capture a signal with as few measurements as possible.The CS sensing is different from the …
