Laser output calibration system for an optoacoustic probe

An optoacoustic probe system for optoacoustic imaging of volume comprising:

• an optoacoustic probe having a distal end operable to contact the volume and a proximal end, the optoacoustic probe;
• a chassis having at least one laser light source configured to generate light that is transmitted along a light path between the chassis and optoacoustic probe to generate optoacoustic return signals when the light reacts with the volume;
• a display disposed on the chassis and configured to display an optoacoustic image based on the optoacoustic return signals;
• a primary sensor configured to detect signals from the light generated by the at least one laser light source;
• a secondary sensor configured to detect the signals from the light generated by the at least one laser light source;
• a microcontroller including one or more processors, and a memory coupled to the one or more processors, wherein the memory stores program instructions, wherein the program instructions are executable by the one or more processors to:
• detect the signals with the primary output sensor;
• determine a first energy output based on the signals detected by the primary sensor;
• detect the signals with the secondary output sensor;
• determine a second energy output based on the signals detected by the secondary sensor;
• compare the first energy output to the second energy output;
• and
• display an alert on the display based on comparing the first energy output to the second energy output.
