Variables

Normalized Detectivity

Normalized Detectivity is used to evaluate the performance of a photodetector. It combines sensitivity and noise characteristics, providing a measure of detection capability across different devices.

Symbol: D_n

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Normalized Detectivity

Detector Area

Detector Area refers to the surface area of a sensor or detector that is exposed to incoming signals or particles. It influences the detection efficiency and sensitivity of the device.

Symbol: A

Measurement: AreaUnit: m²

Note: Value should be greater than 0.

Formulas to find Detector Area

Noise Equivalent Bandwidth

Noise Equivalent Bandwidth represents the bandwidth of an ideal filter that would pass the same noise power as the transducer, affecting its signal-to-noise ratio.

Symbol: Δf

Measurement: FrequencyUnit: Hz

Note: Value should be greater than 0.

Formulas to find Noise Equivalent Bandwidth

Transducer Detectivity

Transducer Detectivity is the detectivity normalized to a unit detector area and detection bandwidth.

Symbol: D_t

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Transducer Detectivity

Go Sensitivity of Photoresistive Transducer

ΔS = \frac{ΔR}{ΔH}

Go Change in Resistance

ΔR = ΔH \cdot ΔS

Go Current Generator Capacitance

C g = C t + C amp + C cable

Go Capacitance of Transducer

C t = C g - (C amp + C cable)

How to Evaluate Normalized Detectivity?

Normalized Detectivity evaluator uses Normalized Detectivity = (Detector Area*Noise Equivalent Bandwidth)^0.5*Transducer Detectivity to evaluate the Normalized Detectivity, The Normalized Detectivity formula is defined as the overall detectivity of the detection system, accounting for both the properties of the detector and the sensitivity of the transducer. Normalized Detectivity is denoted by D_n symbol.

How to evaluate Normalized Detectivity using this online evaluator? To use this online evaluator for Normalized Detectivity, enter Detector Area (A), Noise Equivalent Bandwidth (Δf) & Transducer Detectivity (D_t) and hit the calculate button.

FAQs on Normalized Detectivity

What is the formula to find Normalized Detectivity?

The formula of Normalized Detectivity is expressed as Normalized Detectivity = (Detector Area*Noise Equivalent Bandwidth)^0.5*Transducer Detectivity. Here is an example- 1.992564 = (4.2*0.5)^0.5*1.375.

How to calculate Normalized Detectivity?
