Abstract: The present disclosure relates to a method for constructing the initial structure of an athermal optical system, specifically relating to a method for constructing the initial structure of an athermal optical system based on particle swarm optimization algorithm, which is used to solve the shortcomings of the current athermal optical system designs where optical design software heavily relies on the initial structure of the athermal optical system, and the construction of the initial structure does not consider the selection of optical materials, resulting in extremely low efficiency of the athermal optical system designs. The method for constructing the initial structure of an athermal optical system based on particle swarm optimization algorithm provides a new design concept for the athermal optical system, which achieves a reasonable match between optical materials and mechanical materials in the initial structure stage and improves the efficiency of subsequent design optimization.

Abstract: A method for inputting information includes obtaining a hand image; determining one or more first fingers in an open state in the hand image, and a target touch area touched by a second finger, the target touch area being one of set touch areas pre-divided in the one or more first fingers, in a palm, or in the one or more first fingers and the palm; determining target information to be input according to the one or more first fingers in the open state and the target touch area touched by the second finger.
