Abstract
Embodiments of the present disclosure provide an alternative illuminator assembly and corresponding imaging assemblies utilizing the alternative illuminator assembly. The alternative illuminator assembly may provide alternative illuminations from those produced by an imager engine, such that the alternative illuminations may provide specific illuminations at specific illumination angles to illuminate a field of view for a desired purpose. In an example context, the alternative illuminator assembly provides one or more alternative illuminations for improving the likelihood of successfully reading specific direct part marking indicias of various types. Embodiments are provided using overlapping subassemblies that enable a small form factor assembly that can fit into mobile apparatus chasses, for example within conventional cell phone housings of around 7 millimeters. The alternative illuminator assembly may be provided together with a small form factor imaging engine, having one or more imager, to improve the direct part marking reading capabilities of the multi-sensor imaging apparatus.
