The invention provides a spectral absorption three-dimensional imaging system and method based on parallel light beams and area array detection, relates to the technical field of optical precision measurement and tomography, and aims to solve the problems that high time and high spatial resolution, low system complexity and low cost cannot be compatible at the same time and three-dimensional field distribution cannot be quickly reconstructed with high precision in the prior art. The system comprises a laser emission and modulation module, a beam shaping module, a to-be-measured area, an area array sensor and a data processing module. The light beam shaping module, the to-be-detected area and the area array sensor are arranged on the same plane axis, the light beam shaping module comprises a first collimating mirror and an imaging module which are sequentially connected along a light path, the first collimating mirror forms parallel light beams, and the imaging module performs multi-angle rear two-dimensional imaging; and the area array sensor is electrically connected with the data processing module, is processed and controlled by the upper computer, and reconstructs a two-dimensional image into a three-dimensional field. According to the invention, problems in the prior art are solved, and rapid and high-precision three-dimensional imaging is realized.

This application provides a power supply component and an electronic atomizing device. The power supply component includes a housing, a battery, a bracket, and a seal. The housing has an air inlet, and one end of the housing is an open end. The battery is disposed in the housing. The bracket is disposed in the housing and forms an assembly cavity for accommodating an atomizer between itself and the open end. The bracket has a ventilation cavity communicating with the assembly cavity. The seal is disposed in the bracket and is sealed to the housing. The end of the seal facing the assembly cavity is used to abut against the end of the atomizer for sealing, so that the ventilation cavity and the atomizer are in a sealed communication. The seal has an air inlet channel, which is in a sealed communication with the air inlet and the ventilation cavity. With this configuration, a single seal can achieve a dual sealing function, reducing the number of sealing components, simplifying the structure, and lowering costs.
