Optical dynamic range
Audio engineers use dynamic range to describe the ratio of the amplitude of the loudest possible undistorted signal to the noise floor, say of a microphone or loudspeaker. Dynamic range is therefore the signal-to-noise ratio (SNR) for the case where the signal is the loudest possible for the system. For … See more Dynamic range (abbreviated DR, DNR, or DYR ) is the ratio between the largest and smallest values that a certain quantity can assume. It is often used in the context of signals, like sound and light. It is measured either as a ratio or as a See more The human senses of sight and hearing have a relatively high dynamic range. However, a human cannot perform these feats of perception at both extremes of the scale at the same … See more In metrology, such as when performed in support of science, engineering or manufacturing objectives, dynamic range refers to the range of values that can be measured by a sensor or metrology instrument. Often this dynamic range of measurement is … See more • Loudness war • High dynamic range • Highlight headroom See more In electronics dynamic range is used in the following contexts: • Specifies the ratio of a maximum level of a parameter, such as power, current, voltage or See more In music, dynamic range describes the difference between the quietest and loudest volume of an instrument, part or piece of music. In … See more Photographers use dynamic range to describe the luminance range of a scene being photographed, or the limits of luminance range that a given digital camera or film can capture, or the opacity range of developed film images, or the reflectance range … See more WebThis wide dynamic range is achieved by simultaneously extracting a digital output (single photon counting) for detecting very-low-level light and an analog output for detecting low light levels visible to the human eye.
