Abstract:
In this study, we presented a light-emitting diode-based (LED) miniaturized optical pattern imager for slim mobile phone application. To meet volume constraints, we designed a miniaturized compact illuminating and imaging optical component. The objective was to minimize optical loss using several nano- and micro-fabrication methods. After integration into a single optical body, the prototype imager-with dimensions of 6.8 × 2.2 × 2.5 mm and a weight of 0.4 g-demonstrated clear feasibility in measuring 2D micropatterns with widths of 50 and 10 μm.
