MONITOR AND SYSTEM FOR MONITORING LIVING ORGANISMS

There is provided a monitor (10) that monitors a state of an organism internal part from the surface of the organism. The monitor (10) includes a probe (23) including an observation window (21) attached to the organism surface (2), a unit (25) that emits a laser onto at least part of an observation region (3) on the organism surface (2) accessed via the observation window (21), a unit (27) that detects scattered light 28 caused by emission of the laser from each of a plurality of observation spots that are dispersed in two dimensions in the observation region (3), a Doppler analyzing unit (51) and a SORS analyzing unit (52) that limit, based on the scattered light 28 obtained from the plurality of observation spots, to first observation spots out of the plurality of observation spots where it is evaluated that scattered light including information on a target part of the organism internal part is obtained; and a CARS analyzing unit (53) that acquires spectra of at least one component from the first observation spots or peripheries of the first observation spots and outputs first information showing the state of the organism internal part based on intensities of the spectra.
