Abstract: Embodiments of this disclosure provide a method for starting an application and a related apparatus. The method includes the following: A user terminal may acquire a configuration parameter of a target application from a data management server when a start instruction for the target application is detected. The configuration parameter includes plugin configuration information and code package configuration information. The target application can be executed by using a target code package and a locally cached target plugin.

Abstract: The invention relates to an optical imaging system and method based on spatial structure engineering of random light. The method includes performing scattering processing on transmitted light to obtain a to-be-measured light; splitting polarization of the to-be-measured light, wherein one light is split into x-polarized and y-polarized beams, and the other one is firstly combined with a reference beam and then split into x-polarized and y-polarized beams; measuring the intensity distributions of x-polarized and y-polarized parts of the to-be-measured light, the combined light, and the reference light; obtaining a real part and an imaginary part of the cross spectral density of the to-be-measured light, retrieving the intensity distribution of the light on the scattering medium and calculating the intensity to obtain the shape and location of the object to be measured.

Abstract: The invention discloses an optical imaging system and an imaging method regulated based on a spatial coherence structure, including the steps of: building a 4f imaging system; detecting, by a first optical detector, the shape of the spectrum domain obstacle in the 4f imaging system; designing a spatial coherence structure of the incident beam based on the shape of the spectrum domain obstacle, so that all the modes of the incident beam can pass through the opening in the obstacle; and placing an object to be detected in the optical path and detecting, by the second optical detector, the optical imaging information of the object to be detected. According to the present invention, in the case where the frequency plane of the 4f optical imaging system is partially occluded, imaging without speckles is enabled, utilization of the systematic light is substantially improved, and the signal-to-noise ratio in imaging is improved.
