Changes with Optics<\/strong><\/p>\n

The state-of-the-art Complementary Metal Oxide Semiconductor (CMOS) sensors entering the market have low noise and high Dynamic Range (DR). This high Dynamic Range allows applying more gain maintaining the present day\u2019s requested camera output resolution expressed in bits. As a result the aperture of the lens can be relaxed and selected to balance lens aberrations and lens diffraction. When needed the degree of freedom can even be extended by using a Neutral Density (ND) filter.<\/p>\n

The recent developments in CMOS image sensor technology gives more freedom to select those lens parameters that enhancing its performance, e.g. the Modulation Transfer Function (MTF)<\/a>.<\/p>\n

With some applications it might even be possible to capture the complete DR of the scene expressed in luminance without the need to control the light flux by means of iris diaphragm or variable ND filter. The latter has tremendous advantages, to mention:<\/p>\n
