05.22.19 -- Back Illuminated Sensors, And Other Considerations For CMOS Cameras

 
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, which gives the total number of pixels.

Are Larger Pixels Always More Sensitive?
 

A common myth is that larger pixel size image sensors are always more sensitive than smaller pixel size image sensors. To explain that this isn’t always the case, this paper will look at the effect that the pixel size has on image quality, especially for the overall sensitivity, which is determined by the quantum efficiency.

Why Is A Backside Illuminated Sensor More Sensitive Than A Front Side Illuminated Sensor?
 

Backside illuminated image sensors have fewer obstacles in the pathway of the incoming light as it reaches the volume of the pixel, where the conversion to charge carriers takes place. As a result, backside illuminated CMOS image sensors are able to convert more of the light into charge carriers, resulting in larger signals and better images.

Why You Should Use Back-Illuminated sCMOS Cameras For OEM Development
 

For companies looking to improve image-based systems using scientific CMOS (sCMOS) sensors for OEM applications, it is important to consider the advantages of back-illuminated (bi) systems. This video demonstrates the enhanced capabilities that bi sCMOS sensors have to offer, including up to 95 percent quantum efficiency and a broader spectral response than previous generations.

Why Are There Special Interfaces For The Transmission Of Image Data?
 

The amount of image data that must be transferred to computers for storage and processing is continuously increasing. The demand for fast, reliable data transfer increases in turn. This article discusses the progression of camera interfaces and how they are continuously improved to enable reliable streaming data transfer from the camera to the computer.
