In order to weaken the quenching effect of the metal substrate on surface enhanced fluorescence, a better fluorescent enhanced substrate was designed. In this experiment, the surface of nanoporous gold (NPG) was modified by chemic
Terahertz (THz) wave has strong resonance absorption with the hydrogen bond of polar substances. The bigger the molecular polarity, the stronger the absorption. Based on this characteristic, monohydric alcohol liquids from methano
With the improvement of mobile phone camera requirements and performance, phase detection autofocus (PDAF) module has gradually become the main stream of the market. At this stage, most small and medium-sized module manufacturers
In order to solve the problem of the narrow bandwidth of the substrate integrated waveguide, a new type of ridge substrate integrated waveguide (RSIW) is proposed. Based on the traditional RSIW, the structure is composed of two di
Deep convolution neural network is superior to traditional manual features in the image feature representation, but it still has the problem that the calculation time increases with the increase of data in the loop-closure detecti
Aiming at the problem of amplitude and phase errors in full-waveform light detection and ranging (LiDAR), a method based on neural network and pulse feature parameters is proposed. The feature parameters of waveform, including sha
High dynamic range (HDR) technology has become a new trend of the development of digital microscopes. Currently, due to the high computational complexity, the HDR video cannot be processed and displayed in real-time. Based on REC.
This paper conducted fluorescent spectra of starch powder by using three dimensional fluorescence spectroscopy (EEMs) combined with parallel factors analysis (PARAFAC), revealing that different fluorescence features in the differe
In order to minimize the size of the optical system of Czerny-Turner (CT) spectrometer and prevent interference of incident rays and diffracted rays, a complete selection system of structural parameters is created to satisfy the s
To evaluate the surface of glass elements that achieved by single point diamond turning (SPDT) operation, the wavelet analysis method is employed to analyze surface and surface ripple.In this work, the wavelet analysis method is i
In the actual process of defect detection of printed matter, there is a problem that the standard printed image and the image to be detected are inaccurately registered due to the camera bracket flutter. Therefore, based on the im
The human papilloma virus (HPV) gene chip detection device can read and analyze the hybrid point signal values of the HPV chip to distinguish different HPV virus types. The uniform illumination of the device is related to the diff
In this paper, silicon nitride deposition process was carried out by using plasma enhanced chemical vapor deposition (PECVD). The influence of processing parameters on PECVD film properties were discussed. In conclusion, it was co
Eye tracking refers to tracking eye movement by measuring the position of the eye's gaze point or the movement of the eyeball relative to the head. This paper introduces the eye tracking technology, focuses on the recent research
