Energy Resolution Calculator
Definitions
- Energy Resolution (ER): A measure of the percent of energy of incoming photons on an imaging device.
- Full Width Half Maximum (FWHM): The width of the peak at half its maximum height.
- Photo Peak (PP): The peak value of the photon energy distribution.
Example
Let's say the full width half maximum (FWHM) is 5 and the photo peak (PP) is 100. Using the formula:
\[
ER = \frac{5 \times 100}{100}
\]
We get:
\[
ER = 5 \%
\]
So, the energy resolution is 5%.

How to Calculate Resolution in Physics
Formula: \( \text{Resolution} = \frac{\text{Wavelength}}{2 \times \text{Numerical Aperture}} \)
- Resolution: The smallest distance between two points that can be distinguished
- Wavelength: Wavelength of the light used
- Numerical Aperture: Measure of the lens's ability to gather light
Example: \( \text{Resolution} = \frac{500 \times 10^{-9}}{2 \times 1.4} \)
- Wavelength: 500 nm
- Numerical Aperture: 1.4
How to Calculate Pixel Resolution
Formula: \( \text{Pixel Resolution} = \text{Width} \times \text{Height} \)
- Pixel Resolution: Total number of pixels in an image
- Width: Number of pixels along the width
- Height: Number of pixels along the height
Example: \( \text{Pixel Resolution} = 1920 \times 1080 \)
- Width: 1920 pixels
- Height: 1080 pixels
Energy Resolution of Detector
Formula: \( \text{Energy Resolution} = \frac{\Delta E}{E} \times 100 \)
- Energy Resolution: Ability of a detector to distinguish between different energies
- (\Delta E): Full width at half maximum (FWHM) of the energy peak
- E: Energy of the peak
Example: \( \text{Energy Resolution} = \frac{0.5}{5} \times 100 \)
- (\Delta E): 0.5 keV
- E: 5 keV
How to Calculate Resolving Power
Formula: \( \text{Resolving Power} = \frac{\lambda}{\Delta \lambda} \)
- Resolving Power: Ability to distinguish between two close wavelengths
- (\lambda): Wavelength
- (\Delta \lambda): Smallest difference in wavelength that can be distinguished
Example: \( \text{Resolving Power} = \frac{600}{0.1} \)
- (\lambda): 600 nm
- (\Delta \lambda): 0.1 nm
How to Calculate Video Resolution
Formula: \( \text{Video Resolution} = \text{Width} \times \text{Height} \)
- Video Resolution: Total number of pixels in a video frame
- Width: Number of pixels along the width
- Height: Number of pixels along the height
Example: \( \text{Video Resolution} = 3840 \times 2160 \)
- Width: 3840 pixels
- Height: 2160 pixels
Total Energy Requirement Calculator
Formula: \( \text{Total Energy} = \text{Power} \times \text{Time} \)
- Total Energy: Total energy required
- Power: Power consumption (in watts)
- Time: Duration of usage (in hours)
Example: \( \text{Total Energy} = 100 \times 5 \)
- Power: 100 W
- Time: 5 hours
