The Advanced Hyperspectral Imager (AHSI) is a visible/short-wave infrared hyperspectral imager on China's GaoFen-5 satellite, which was launched on May 9th, 2018. The AHSI is the first spaceborne hyperspectral sensor that utilizes both the convex grating spectrophotometry and an improved three concentric-mirror (Offner) configuration. It has 60 km swath width, 30 m spatial resolution, 5-10 nm spectral resolution, and 330 spectral bands. Instrument performance was evaluated and validated through well-designed experiments on orbit. Results show that the performance of AHSI has met or exceeded predictions. The AHSI has outstanding capability of detecting and identifying different ground objects and in ecological environment monitoring and natural resource exploration.

Tianjin UniversityTianjin 300072n this paper the propagation characteristics of near-infrared (NIR) light in the palm tissue are analyzed and the principle and feasibility of using transcutaneous diffuse reflectance spectroscopy for non-invasive blood glucose detection are presented. An optical probe suitable for measuring the diffuse reflectance spectrum of human palm and a non-invasive blood glucose detection system using NIR spectroscopy are designed. Based on this system oral glucose tolerance tests are performed to measure the blood glucose concentrations of two young healthy volunteers. The partial least square calibration model is then constructed by all individual experimental data. The final result shows that correlation coefficients of the two experiments between the predicted blood glucose concentrations and the reference blood glucose concentrations are 0.9870 and 0.9854 respectively. The root mean square errors of prediction of full cross validation are 0.54 and 0.52 mmol/1 respectively.

Deployment of modern detection models is difficult for infrared target detection used in robot vision systems due to their heavy computational burden. To alleviate this situation, a simple but efficient channel pruning method is proposed for model acceleration. Specifically, a soft-gated module combined with batch normalization (SGBN) is designed as a standalone layer to substitute the standard batch normalization (BN) layer during training. The conversion between SGBN and BN is easy, and the training overhead introduced is almost negligible after replacement. By controlling the sparsity of the scaling factor in SGBN, unimportant channels with small output are blocked automatically and globally, which is simultaneous with model training. Removing these redundant channels no longer requires fine-tuning, thus significantly speeding up the pruning process. Experiments of pruning different detection models on the infrared dataset show the effectiveness of our method. For example, the parameters and FLOPs of pruned CetnerNet are reduced by 72.70% and 40.20%, respectively, without accuracy loss. The inference speed on the CPU is 12.01ms faster. Extended studies on the classification task also demonstrate its great potential when transferring to other applications.
