Determination of Crystal Structures

Determination of Crystal Structures

In the late 1800s, the revelation that light extended beyond visible wavelengths led to the discovery of X-rays by Wilhelm Roentgen. Recognized as high-energy electromagnetic radiation with short wavelengths, X-rays prompted exploration into their interaction with crystals. Max von Laue proposed in 1912 that the periodic arrangement of atoms, ions, or molecules in crystals would cause them to diffract X-rays, a hypothesis confirmed through experiments with copper sulfate and zinc sulfide...

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used.

Background:

Ladar systems require efficient target detection algorithms, especially against complex backgrounds like the sky.
Geiger-mode avalanche photodiodes (GAPDs) are increasingly used in ladar due to their sensitivity.
Existing detection methods may not fully account for GAPD dead-time characteristics, impacting performance.

Purpose of the Study:

To develop an optimal algorithm for target detection in ladar systems using GAPDs.
To create a statistical model for GAPD detection processes, including dead-time effects.
To minimize target acquisition time while maintaining a constant false alarm rate.

Main Methods:

Development of a comprehensive statistical model for GAPD detection, incorporating dead time.
Design of a constant false alarm rate (CFAR) detection algorithm based on the statistical model.
Validation through numerical performance predictions, simulations, and experimental data.

Main Results:

The proposed algorithm achieves optimal target detection performance for ranging direct detection ladar.
The statistical model accurately represents GAPD behavior, including dead-time effects.
The CFAR algorithm effectively minimizes acquisition time across various scenarios.

Conclusions:

The presented optimal algorithm enhances target detection capabilities in ladar systems employing GAPDs.
The statistical model and CFAR algorithm provide a robust framework for ladar signal processing.
This work contributes to improved performance in direct detection ladar for target identification.
