Single-Pixel Imaging

  • High-resolution imaging for X-ray, UV, visible, IR, and THz detectors
  • DMD-based modulation for visible/NIR; custom masks for X-ray/THz
  • Single-pixel detector reconstructs up to 1024×1024 images; typical 256×256

Compressed Spectral Imaging

  • Snapshot hyperspectral imaging bypassing traditional scan trade-offs in spatial-temporal-spectral resolution
  • Single-frame grayscale can reconstruct dozens of hyperspectral frames
  • Supports large-area imaging chips: max 1024×1024; spectral resolution up to 2 nm, max 190 bands; typical 30–60 bands

Compressed Temporal Imaging

  • Evaluates temporal response and intensity linearity of imaging chips
  • Single camera + spatial light coding reconstructs dozens of dynamic frames from one snapshot
  • Max 1024×1024; typical 256×256; frame rate boosted 10–100× depending on scenario

Semiconductor Device Characterization & Testing

  • Electrical characterization including I–V, dark current, photocurrent, turn-on voltage, and noise measurements
  • Quantitative evaluation of leakage current, junction quality, and device interface performance
  • Optoelectronic testing including External Quantum Efficiency (EQE), responsivity, detectivity (D*), spectral response, and response time
  • Supports device performance benchmarking, process validation, and technology development

Detector Quantum Efficiency (DQE) Measurement

  • Integrates DQE, Noise Power Spectrum (NPS), and Modulation Transfer Function (MTF)
  • Adaptive algorithms remove fixed-pattern noise, dead pixels, horizontal striping, and perform per-pixel gain calibration.
  • Supports scintillators (CsI, LYSO), semiconductors (CdZnTe, perovskites), and EM-shielded packaging
  • Meets IEC 62220-1 standards for metrology-grade SWIR/X-ray imaging systems

Scintillator Light Yield Measurement

  • Absolute photon yield measurement (photons/MeV) under radiation or particle excitation
  • High accuracy, sensitivity, and material compatibility (inorganic, organic, novel scintillators)
  • Key for new scintillator characterization, radiation detector selection, and medical imaging components (e.g., PET)
