However, owing to its weak reactivity, the NH<sub>3</sub>-containing flame suffers from severe combustion instability, leading to large amounts of NH<sub>3</sub> emission in exhaust gas. In order to quantify the NH<sub>3</sub> emission, reliable and efficient diagnostic has to be developed. In this work, a mid-infrared high-sensitivity laser measurement system based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology was developed for detecting NH<sub>3</sub> emission of NH<sub>3</sub>/CH<sub>4</sub> swirl combustion. Quantum cascade lasers (QCLs) is used to detect the optimal absorption features of NH<sub>3</sub> centered at 1103.45 cm<sup>−1</sup>, combining with the direct absorption spectroscopy and a high temperature gas cell. Firstly, the performances of the measurement system was evaluated. The results show that the maximum relative error is less than 5 % and the measurement precision is 2.3 %. The minimum detection limit (MDL) at the optimal integration time of 49 s reaches 4.27 ppm. Subsequently, the measurement system was applied to detect NH<sub>3</sub> emission in exhaust gas of a swirl CH<sub>4</sub>/NH<sub>3</sub> co-firing flame. The NH<sub>3</sub> emission were successfully discerned, with a minimum of 26 ppm and a maximum of 738 ppm under present conditions.

In this method, the spatial phase compensation algorithm is first applied to address the issue of phase inconsistency in the array detector signals. Subsequently, to handle the phase mismatch across multiple frames of the GM-APD signals, a time-phase compensation algorithm is employed to align the phases of the multi-frame signals. Finally, the signals are accumulated in the time domain across multiple frames to obtain the final processed signal. A spatial photon coherent lidar system was established to detect four different targets. The application of this algorithm results in a significant improvement in the SNR, with the maximum increase reaching approximately 14.43 dB and the minimum increase at around 8.45 dB.

A CO sensor is engineered utilizing the principle of non-dispersive infrared (NDIR). The sensor consists of a broadband infrared light source (HIS2000R-0WC), a 3-meter path multi pass gas chamber (MPCC), and a dual channel pyroelectric detector. The center wavelengths of the two filters in the detector are 4.66 μm and 3.95 μm, respectively. An enhanced wavelet threshold denoising algorithm based on adaptive noise complete ensemble empirical mode decomposition with adaptive noise (EWTD-CEEMDAN) has been developed to enhance the signal-to-noise ratio (SNR) of voltage differential ratio signal. The proposed method demonstrates an approximate increase of 9.57 dB in SNR. The Zebra Optimization Algorithm-Least Squares Support Vector Machine (ZOA-LSSVM) algorithm model is employed to invert the CO concentration with a determination coefficient (R<sup>2</sup>) of 0.99992. Temperature compensation is performed to enhance the precision of sensor detection. According to the Allan-Werle deviation, the theoretical limit of detection (LoD) for CO is 9.56 ppb when the sensor integration time is 201 s.

Specifically exciting only the first-order Stokes light within the optical fiber notably enhanced the side-mode suppression ratio of microwave signals.

At an offset frequency of 10 kHz, the corresponding phase noise of the microwave signal was measured at −101.534 dBc/Hz.
