What is the detectivity of transducer?

The detectivity of a transducer is a key measure of its ability to detect weak signals amidst noise. It is defined as the inverse of the noise-equivalent power (NEP) normalized to the detector area and bandwidth. Higher detectivity indicates a more sensitive detector, capable of distinguishing weaker signals. This is crucial in applications such as infrared imaging, spectroscopy, and other fields where detecting minute amounts of light or radiation is necessary.

How to Calculate Detectivity?

Detectivity calculator uses Transducer Detectivity = Detector Responsivity/Root Mean Square Noise Voltage of Cell to calculate the Transducer Detectivity, The Detectivity formula is defined as how effectively the transducer can detect weak signals relative to the input signal level and the noise present in the output signal. Higher detectivity values indicate a more sensitive transducer capable of discerning smaller signals amidst noise. Transducer Detectivity is denoted by D_t symbol.

How to calculate Detectivity using this online calculator? To use this online calculator for Detectivity, enter Detector Responsivity (R_d) & Root Mean Square Noise Voltage of Cell (E_n) and hit the calculate button. Here is how the Detectivity calculation can be explained with given input values -> 0.727711 = 15.1/10.98.
