    There are many current DVE systems that use passive thermal imaging systems to enhance a driver’s viewing capabilities while operating in darkness, fog, smoke, dust, etc. SWIR has emerged as a leading technology that meets the needs of DVE. 

  7. Drone-Based Daylight EL Imaging Of PV Modules Using SWIR Cameras 6/30/2020

    Electroluminescence (EL) imaging of photovoltaic (PV) solar panels provides high accuracy in detecting defects and faults. Further, the EL technique is used extensively due to a high level of detail and direct relationship to injected carrier density.

  8. Silicon Wafer Inspection With SWIR Cameras 6/9/2020

    Silicon inspection can be challenging for silicon and semiconductor manufacturers in terms of pattern alignment, pattern defect inspection, and edge position bonding inspection. Foreign particles and defects may affect the wafers. This article discusses the use of silicon wafer inspection with SWIR cameras.

  9. Technical Note: Auto Gain Control And Non Uniformity Correction 6/9/2020

    In SWIR cameras, the InGaAs FPA sensor can be difficult to manufacture so that all pixels are fully functional. As a solution, Raptor Photonics cameras use Non-Uniformity Corrections (NUC), or gain and dark current corrections, in order to obtain the same quality as a single A/D device. In addition, Raptor’s family of SWIR cameras is also capable of continuously performing Auto Gain Control (AGC) on the onboard FPGA. This application note goes into detail about the NUC and AGC features included in Raptor’s new SWIR cameras.
