Abstract

The disclosure relates to a handheld device (1) and system for optoacoustic imaging of an object (3), the device (1) comprising a housing (2) configured to be grasped by an operator's hand and guided and/or positioned by the operator relative to the object (3) during imaging, wherein the following components are integrated in and/or provided on the housing: a) an illumination unit (4, 6) configured to illuminate the object (3) with time-varying electromagnetic radiation (5), the illumination unit (4, 6) comprising at least one radiation source (4, 6), in particular at least one laser diode (LD), vertical-cavity surface-emitting laser (VCSEL) or light-emitting diode (LED), having a front side (4a) and a back side (4b) opposite the front side and configured to emit the electromagnetic radiation (5) at the front side (4a) of the at least one radiation source (4), the illumination unit (4, 6) further comprising a first electronic controller (6) provided at the back side (4b) of and/or close to the at least one radiation source (4) and configured to control the at least one radiation source (4) to emit pulses of electromagnetic radiation (5) exhibiting at least one of a predefined electromagnetic spectrum and/or wavelength(s), pulse amplitude, pulse shape, pulse width (duration) and/or pulse repetition rate, and b) a detection unit (7, 9) configured to detect ultrasonic waves (8) emanating from the object (3) in response to illuminating the object (3) with the time-varying electromagnetic radiation (5), the detection unit (7, 9) comprising at least one ultrasonic transducer (7), in particular at least one micromachined ultrasonic transducer (MUT) and/or at least one piezoelectric ultrasonic transducer (PUT), having a front side (7a) and a back side (7b) opposite the front side and configured to convert ultrasonic waves (8) impinging at the front side (7a) of the at least one ultrasonic transducer (7) into detection signals, the detection unit (7, 9) further comprising a second electronic controller (9) provided at the back side (7b) of the at least one ultrasonic transducer (7) and configured to process the detection signals, in particular to digitize and/or filter the detection signals and to reconstruct an image of the object (3) based on the digitized and/or filtered detection signals.
