What Are All The Discussions About Global Vs. Rolling Shutter?
The shutter in a camera system enables the control of the exposure time and thus, the level of signal in an image. The shutter also defines the quality of an image if the objects are moving, as well as setting the environment for experiments, especially involving synchronization with illumination light.

Is It True That Cooled Cameras Are More Sensitive Than Non-Cooled Cameras?
The reduction of temperature through “cooling” of image sensor components or electronic circuits can improve image quality and performance. This paper will examine the underlying effects of cooling in cameras and their sensitivities.

Understanding A Camera’s Resolution
The resolution of an image sensor describes the total number of pixels that can be used to detect an image. From the standpoint of the image sensor, it is sufficient to count the number and describe it usually as the product of the horizontal number of pixels times the vertical number of pixels.

Dynamic Range: What Is It Good For Anyway?
Since many camera manufacturers define dynamic range from a different point of view, a distinction should be made between the “dynamic range of an sCMOS, CMOS, or CCD image sensor,” “dynamic range of an analog-to-digital-conversion,” “usable dynamic range,” and “maximum dynamic range or SNR.”

Raman Spectroscopy Enhanced By A Back-Illuminated sCMOS Camera
Operating in a climate-controlled lab or on the Martian surface, back-illuminated sCMOS detectors provide high sensitivity, high dynamic range, and low noise, even in in low-light conditions.
