Abstract: An apparatus may include a platen, an electromagnetic interference (EMI)-reducing system including a first EMI-reducing layer, a light source system and a receiver system. The light source system may include a light-emitting component, light source system circuitry and a light guide system and may be configured to emit light through the first EMI-reducing layer to a first platen area via a light pipe between the first EMI-reducing layer and the platen. The light guide system may include a light-directing element for directing light from the first EMI-reducing layer to the light pipe. The receiver system may be configured to detect acoustic waves corresponding to a photoacoustic response of a target object in contact with the first platen area to light emitted by the light source system. The first EMI-reducing layer may reduce a level of EMI emitted by the light source system circuitry that is received by receiver system circuitry.

Abstract: Some disclosed devices include a light source system, a target detection system; and a control system configured to communicate with the light source system and the target detection system. The control system may be further configured to receive target detection data from the target detection system, to estimate the presence or absence of a biological target based, at least in part, on the target detection data and to enable or disable the light source system based, at least in part, on an estimation of the presence or absence of the biological target. For example, if the biological target is detected, the control system may enable the light source system.
