2. The Long – Focus Crossed Asymmetric CT Spectroscopic System

2.1 System Architecture

The long – focus crossed asymmetric CT spectroscopic system typically consists of a light source, a sample chamber, a set of optical components for beam shaping and focusing, a detector, and a data acquisition and processing unit. The light source emits a broad spectrum of light, which passes through the sample in the sample chamber. The optical components are designed to manipulate the light beam, creating a long – focus and crossed asymmetric configuration. This unique geometry allows for enhanced interaction between the light and the sample, enabling more detailed spectroscopic analysis.

2.2 Working Principle

When light interacts with the sample in the long – focus crossed asymmetric CT spectroscopic system, it undergoes absorption, scattering, and emission processes. These processes are highly influenced by the illuminance of the incident light. The amount of light absorbed or scattered by the sample depends on the intensity of the incident light, which is directly related to the illuminance. By measuring the changes in the light spectrum after passing through the sample, valuable information about the sample’s composition, structure, and properties can be obtained.

3.2 Illuminance Measurement Methodology

To measure illuminance in the long – focus crossed asymmetric CT spectroscopic system using the LISUN LMS – 6000 Portable CCD Spectroradiometer, the instrument is carefully positioned at the appropriate location within the system to capture the incident light. The spectroradiometer measures the intensity of the light across different wavelengths and calculates the illuminance based on the integration of the light intensity over the visible spectrum.

4. The Impact of Illuminance on the Long – Focus Crossed Asymmetric CT Spectroscopic System

4.1 Signal – to – Noise Ratio

Illuminance has a significant impact on the signal – to – noise ratio (SNR) of the spectroscopic measurements. Higher illuminance levels generally result in a stronger signal, which can improve the SNR. When the SNR is improved, the accuracy and reliability of the spectroscopic data increase. Table 1 shows the relationship between illuminance and SNR in the long – focus crossed asymmetric CT spectroscopic system.

As shown in Table 1, as the illuminance increases, the SNR improves significantly. This indicates that higher illuminance levels can enhance the quality of the spectroscopic measurements.

4.2 Detection Limit

The detection limit of the long – focus crossed asymmetric CT spectroscopic system is also affected by illuminance. A higher illuminance can increase the sensitivity of the system, allowing for the detection of smaller amounts of substances in the sample. Figure 1 shows the relationship between illuminance and the detection limit of a particular analyte in the sample.

It can be seen that as the illuminance increases, the detection limit decreases, demonstrating the positive impact of illuminance on the detection capabilities of the system.

4.3 Measurement Accuracy

Illuminance plays a crucial role in ensuring the accuracy of spectroscopic measurements. Inaccurate illuminance levels can lead to errors in the measurement of the sample’s properties. For example, if the illuminance is too low, the measured absorbance or emission values may be underestimated, resulting in incorrect conclusions about the sample’s composition. On the other hand, if the illuminance is too high, saturation effects may occur, leading to inaccurate measurements. Therefore, precise control and measurement of illuminance are essential for obtaining accurate spectroscopic data.

5. Experimental Studies on the Influence of Illuminance

5.1 Experimental Setup

To investigate the impact of illuminance on the long – focus crossed asymmetric CT spectroscopic system, a series of experiments were conducted. The LISUN LMS – 6000 Portable CCD Spectroradiometer was used to measure and control the illuminance levels. Different samples with known compositions were placed in the sample chamber of the spectroscopic system. The light source was adjusted to provide different illuminance levels, and the spectroscopic data was collected and analyzed for each illuminance condition.

5.2 Experimental Results

The experimental results showed that as the illuminance increased, the quality of the spectroscopic data improved. The peaks in the spectra became more distinct, and the signal – to – noise ratio increased. Table 2 shows the results of the analysis of a particular sample under different illuminance conditions.

From Table 2, it can be observed that with increasing illuminance, the peak intensity increased, the FWHM decreased, and the SNR improved, indicating better resolution and accuracy of the spectroscopic measurements.
