Abstract: A dispersion gating-based atmospheric composition measurement laser radar. The atmospheric composition measurement laser radar stretches a femtosecond laser into a broad pulse laser in a time domain by means of dispersion. A femtosecond spectrum is mapped into the broadened laser pulse due to the group velocity dispersion, and then is subjected to time domain gating by means of an intensity modulator (22, 26) for completing the selection of a laser of a preset wavelength. The laser wavelength scanning is achieved by adjusting the delay of an electrical drive signal of the intensity modulator (22, 26). An absorption spectrum of a specific atmospheric composition is obtained by means of laser wavelength scanning so as to measure the concentration of the atmospheric gas composition. The atmospheric composition measurement laser radar can precisely perform free gating on the wavelength where the laser emits, and has high precision in selecting the wavelength. Scanning and detection of a plurality of gases can be achieved by adjusting the center wavelength of a filter.

Abstract: A sequence signal generator and a sequence signal generation method are provided. In the sequence signal generation method, a waveform output instruction sent by a host computer is received to acquire waveform data. The waveform data includes original square wave sequence data and target square wave sequence data, and the target square wave sequence data includes a preliminary delay parameter and a secondary delay parameter. An original square wave sequence signal is acquired according to the original square wave sequence data. According to the preliminary delay parameter, preliminary delay processing is performed on the original square wave sequence signal to acquire an intermediate square wave sequence signal, and according to the secondary delay parameter, secondary delay processing is performed on the intermediate square wave sequence signal to acquire a target square wave sequence signal.

Abstract: Embodiments of this application disclose an interpolation filter training method and apparatus, a video picture encoding and decoding method, an encoder, and a decoder. According to the training method, a first sub-pixel picture obtained through interpolation by using a conventional interpolation filter is used as label data, to train a second interpolation filter, so that the second interpolation filter obtained through training can be directly used for a pixel value, obtained through interpolation, of a first fractional pixel position. Therefore, the label data is more accurate, and coding performance of a video picture is improved. According to the encoding method, during inter prediction, a target interpolation filter used for a current encoding picture block is determined from a set of candidate interpolation filters, and the encoder selects, according to content of the current encoding picture block, an appropriate interpolation filter to perform an interpolation operation.
