Solo Spectroscopy’s monolithic spectrometer chip approach offers a radical departure from traditional spectroscopy techniques and so overcomes many of the challenges and costs associated with a spectrometer payload and with increased reliability. Unlike conventional approaches, there is no trade-off between size and spectral resolution. Its physical dimensions (minuscule size, low mass and low power requirement) result in minimal impact on payload and its highly robust structure provides insensitivity to vibrations, and extremes of temperature whilst offering built in redundancy.

Spectrometer chips or chip arrays offer mass producible-high performing spectroscopy that can support future space agency goals for earth observation, space science or in-orbit spectrometer calibration applications. For example, Solo Spectroscopy is:

  • Small/micro/nanosatellite-compatible which supports the realisation of dispersed (swarm) networks of small satellites offering more frequent imaging opportunities and more timely data download. For remote sensing and earth observation Solo Spectroscopy 1D chip arrays can produce 2D (spatial & wavelength) data from a single pass.
  • Dynamically (re-)configurable in orbit enabling the collected data to be tailored to specific operational requirements making for efficient onboard data analysis within memory and data-transmission rates currently achievable.
  • High cosmic ray resistance owing to the choice of III-V materials used to fabricate the semiconductor spectrometer chips.
  • Inherently extremely robust and able to withstand the vibration associated with launch and strong temperature fluctuations.
  • Optically superior allowing improved spectral resolution without compromising spatial resolution.

We are currently investigating a number of space-based applications for Solo Spectroscopy including:

  • Improved spectral and spatial resolution for maritime imaging purposes
  • Methane, carbon dioxide and other atmospheric gas monitoring
  • Ground and space-based calibration of space-based satellites
  • Spectroscopic applications for exploration
