Abstract

A numerical model has been developed for a three-channel ring-shaped LED lighting device designed for a visual automated inspection system for sealing joints on small CubeSat 1U and 2U spacecraft using a machine vision camera. The model assumes the periodic operation of three different spectral channels - ultraviolet, visible green, and near-infrared ranges of the spectral distribution of light and is formulated as a two-level variational problem linking the discrete arrangement of LED light sources with a continuous set of their light characteristics, subject to constraints on uniformity and sufficiency of illumination in the visual control zone. The model is presented as a two-level variational optimization problem linking the binary topology of emitter placement and continuous levels of their light brightness with restrictions on the uniformity of illumination and thermal load; The numerical implementation of the model is performed by approximating point emitters by the shape of a Lambertian object and discretizing the controlled area with a diameter of 40 mm with a step of 0.5 mm, three rings of 36 sources at radii of 70, 85, and 100 mm, and a working height of 55 mm. Simulation results meet the target radiometric and photometric specifications: mean irradiance for the ultraviolet channel of 5.1 mW/cm²; mean illuminance for the green channel of 10.3 klx; and mean irradiance for the near-infrared channel of 30.4 mW/cm². The composite-field uniformity index equals 0.87, and, relative to a regular equal-angular arrangement, the variance of the composite field is reduced by 34 %. These findings substantiate the suitability of the model for the design and optimization of spectrally adaptive, three-ring LED illuminators-spanning source placement topology, spectral composition, and drive levels-required by machine-vision systems for visual inspection during modular assembly and sealing of small spacecraft enclosures.
