High speed Imaging

Fast phenomena can only be studied, when recorded at high frame rate. This requires special architectures with low noise read-out chains to compensate for low light levels.

  • High sensitivity: ≥ 100 µV/e– and low noise operation: ≤ 2 e–rms
  • Technology Global Shutter (6T pixel) operation
  • Multi-row access to reduce row overhead time
  • Block or segment wise read-out to achieve faster frame rates
  • Colour Filter Array (CFA) and Micro lens technologies are available

Sorting & hyperspectral imaging

Colour fidelity is the keyword for sorting applications. Whether a linear or area detector is used; the colour signal shall remain unchanged over the full array.

  • Low etaloning with optimised technologies
  • Custom designed pixel architecture and technology
  • Flexible timing (shutter modes & integration control)
  • Fast frame rates for hyperspectral imaging

Quality Inspection

Vision is the ideal non-contact technique for quality inspection. Global shutter, high speed and high dynamic range are important to cope with fast throughput and low light environment.

  • Low light level operation: Gain ≥ 100 µV/e–
  • In-pixel anti-blooming
  • Technology Global Shutter (5T and 6T pixel) to avoid jello and skewness
  • Low noise operation: ≤ 2 e–rms

Food Safety

Stimulated light processes, like fluorescence and Raman, are becoming available as in line inspection tools. They require image sensors with precise integration control and high gain, low-noise operation.

  • Short integration time to capture fluorescence peak
  • Accurate timing delay to discriminate fluorescence signals
  • Noise ≤ 0.3 e–rms (4T pixels and oversampling) for Raman detection
  • Low etaloning over the full array
  • Photon shot noise limited behaviour when using SPAD’s
