Abstract: An n-lane automatic license plate recognition system (where n is an integer greater than one) and a method for dropping video frames in this system is disclosed. The method includes receiving, at an input of a first stage of a two-stage restrictor, a plurality of video frames. In the first stage of the two-stage restrictor, a subset of the plurality of video frames is dropped. An output of the first stage is coupled to an input of a second stage of the two-stage restrictor such that receiving and non-receiving of individual ones the plurality of video frames by the second stage is controlled by the first stage. In the second stage after the first stage, a further subset of the plurality of video frames is dropped to effect controlled frame input into a processor that performs at least one recognition analytic on remaining video frames of the plurality of video frames. The dropping of the further subset is based on at least one drop condition including a lane-specific drop condition.

Abstract: The present disclosure provides a detection system for acquiring the SPR angle, including a modulatable SPR sensor to be detected; an incident light source apparatus; a photoelectric detector; a narrowband filter system; a modulated signal source for generating an alternating current signal that is used to modulate said modulatable SPR sensor; and a data processing system for recording the corresponding relationship between the incident angle and the intensity of the filtered reflected light and further obtaining the resonance angle of said modulatable SPR sensor. The present disclosure also provides a corresponding detection method for acquiring the SPR angle.

Abstract: The invention provides an SPR measuring method and a measuring system thereof. According to the measuring method, first, a linear-polarized coherent broadband pulsed light beam is incident onto a surface of a sample under detection of a SPR sensing device to cause reflection; next, a time-domain monotonous chirp is performed on the incident coherent broadband pulsed light and/or the SPR reflected light; finally, the time-domain monotonically chirped SPR reflected light beam is detected, and information of the SPR effect is obtained according to the detected signal. According to the invention, the spectrum detection method used in conventional slow wavelength interrogation is converted into the high-speed real-time detection of time-domain pulse shape signals. Thus, the procedure of the SPR reaction may be monitored closely, and dynamical curves with very high time resolution may be obtained, in that case, fast biochemical reaction procedures may be monitored.
