| 摘要 |
The present invention provides a measuring apparatus having: a first probe including a first acoustic conversion element that transmits an ultrasound wave, receives the ultrasound wave after the ultrasound wave is reflected by an object, and converts the ultrasound wave into an analog signal; a second probe including a second acoustic conversion element that receives a photo-acoustic wave generated when light emitted from a light emitter is absorbed by the object and converts the photo-acoustic wave into an analog signal; a receiver that receives the analog signals converted by the first and second acoustic conversion elements and converts the analog signals into digital signals; and a switching unit that switches the acoustic conversion element from which the receiver receives the analog signal.
