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.

Short-Wave Infrared Temporal Multiplexing For Cost-Effective Multispectral Solutions
6/19/2018
Temporal multiplexing is an alternative approach to hyperspectral imaging that uses a fast LED technology. Instead of broadband illuminating and diffracting the spectrum of light in the camera, a broadband sensitive chip is used, and the illumination spectrum is varied over time via fast triggering.
