2023年6月27日 · Resolution of a sensor refers to the smallest change in the quantity being measured that the sensor can detect and distinguish from noise and other sources of error. In other words, it is the smallest incremental change in the input signal that the sensor can detect and accurately measure.

Understand the crucial distinctions between resolution and accuracy in sensor measurements (precision vs resolution). Explore the concept of sensor resolution and its relationship with accuracy (resolution of a measurement). Gain insights into the intricacies of resolution versus accuracy in measurement systems (accuracy vs resolution).

Simply put, the resolution is: the smallest possible change that a sensor can perceive. For a laser light grid, for example, this is a shift in position. A sensor with a low(er) resolution will only detect or report displacements in whole centimetres, for example.

SNR是用来衡量Sensor输出的图片质量，一般手册提供最大SNR值，并且提供计算该SNR值的条件，比如曝光时间、增益档位等。 计算公式，计算信号与噪声的比值：

Resolution is an imaging system’s ability to reproduce object detail. It can be influenced by factors such as the type of lighting used, the sensor pixel size, and the capabilities of the optics. The smaller the object detail, the higher the required resolution.

2024年4月8日 · Sensor resolution refers to the level of detail captured by remote sensing devices. There are two main types: spatial resolution and spectral resolution. Spatial resolution tells us how clear the images are, while spectral resolution tells us how well the sensors can detect different colors or wavelengths of light.

Radiometric Resolution •Number of digital levels that a sensor can use to express variability of brightness within the data •Determines the information content of the image •The more levels, the more detail can be expressed

By understanding sensor resolution, its relationship to bandwidth, the different units of measure, and how they are listed in datasheets, you can now make more confident decisions about your displacement sensors.

2013年8月9日 · Essentially, a resolution is the smallest measurement a sensor can reliably indicate. Before discussing this in any detail, it is important to understand what resolution is not; it is not accurate. A very inaccurate sensor can have a very high resolution, and a low-resolution sensor may be very accurate in some applications.
