Abstract

A testing apparatus for an optoacoustic device includes a light pulse sensor operatively connected to a light output port of the optoacoustic device, the light pulse sensor being adapted to sense a pulse of light capable of generating an optoacoustic response in a subject and to distinguish between the light pulse and the at least one other light pulse on the basis of the predominant wavelength. The light pulse sensor outputs a trigger signal associated with the distinguished light pulse when such light pulse is sensed. A transducer signal simulator outputs a first plurality of electrical signals simulating those produced by a transducer array and reflective of an optoacoustic response in a subject to a light pulse at a first wavelength in response to a trigger signal from the light pulse sensor associated with a light pulse having a first wavelength. The simulator outputs a second plurality of electrical signals simulating those produced by a transducer array and reflective of an optoacoustic response in a subject to a light pulse at a second predominant wavelength in response to a trigger signal from the light pulse sensor associated with a light pulse having a second wavelength. Conductors carry the plurality of electrical signals output by the transducer signal simulator to the pins of a multi-pin connector.
