A large portion of near infrared (NIR) laser energy is lost at the skin surfaces by reflection, for example 30% of the incident energy reflects off with incident angle of 20°. Retrieving the reflected light and redirecting it onto the skin surfaces will increase the effective excitation energy, resulting in an increased photoacoustic (PA) signal for the same light source without increasing power....
