10 Apr How can the InvestiGater improve images with low signal and high noise?
The InvestiGater enables the acquisition of “noise free” low light level images from the IR-1000 (Spectral response 380nm to 1100nm). The InvestiGater accomplishes this by “gating” (allowing a number of frames to accumulate charge on the CCD detector), grabbing and displaying the image. As long as the signal is present above background noise, the signal from the sample will build up faster than random noise. Unlike Image averaging, the InvestiGater will “normalize” the image to change the range of pixel intensity values to maximize the contrast (histogram or contrast stretching). This can result in brilliant images from low light/low signal environments.
