Applications

Medical imaging

Our sensors have enormous potential for non-invasive health monitoring devices and wearable technologies

For example, our sensors can enable blood flow in the brain to be monitored by detecting rapid fluctuations in light as it passes through tissue using a technique called diffuse correlation spectroscopy.

Techniques enabled:

  • Diffuse correlation spectroscopy (DCS)
  • Optical Coherence Tomography (OCT)
  • Fluorescence Lifetime Imaging (FLIM)
  • Bioluminescence and Chemiluminescence Imaging

Scientific instrumentation

Our sensors can be used in various scientific and technical applications, particularly where precise and sensitive light detection is critical.

For example, our patented on-chip histogram feature enables researchers to measure the lifetime of fluorophores in fluorescence lifetime imaging, or separate Raman signals from fluorescent signals in spectroscopy applications.

Techniques enabled:

  • Diffuse Correlation Spectroscopy (DCS)
  • Fluorescence Lifetime Imaging (FLIM)
  • Fluorescence Spectroscopy
  • Raman Spectroscopy
  • Flow Cytometry

Environmental sensing

Due to their exceptional sensitivity and precise timing capabilities, our sensors are well suited to various environmental applications, providing accurate and detailed data essential for monitoring and protecting the environment.

Techniques enabled:

  • Fluorescence-Based Environmental Sensing
  • Environmental Radiation Detection
  • Raman spectroscopy
  • Time-Resolved Fluorescence

Quantum sensing

Our sensors can also support the development of quantum technologies due to their ability to detect and time single photons with high efficiency and precision, low timing jitter, and low dark count rates.

Techniques enabled:

  • Coincidence and inter-arrival counting
  • Quantum Imaging
  • Quantum Computing
  • Quantum Optics Research
  • Quantum materials characterisation
