Comparison of CCD, CMOS and intensified cameras
- 1.8k Downloads
The properties of digital cameras are often important to obtain accurate results with image based measurement techniques. Unfortunately, a detailed comparison of the sensor specifications and performance is not accessible as this information is normally not provided by the manufacturers and no generally accepted comparison standard exists. Therefore, a detailed quantitative comparison was performed to evaluate and assess the characteristics of state-of-the-art CCD, CMOS and intensified CMOS sensors. These results may be of assistance when selecting the appropriate sensor for a desired application.
