Abstract
Some disclosed examples pertain to an apparatus that can include a platen, a light source system, a receiver system, and an electromagnetic interference (EMI) shield. The light source system can include light source system circuitry, a light-emitting component, and a light guide component having a substantially uniform cross-section. The light-emitting component provides light to an area of the platen via the light guide component. The receiver system can include at least two receiver stack portions residing proximate on either side of the light guide component. The receiver system detects acoustic waves corresponding to a photoacoustic response of a target object proximate the area of the platen, to light emitted by the light source system. The EMI shield shields the receiver system from at least some of the EMI produced by the light source system circuitry. The light guide component conveys light through a portion of the EMI shield.
