Abstract
An optical measurement apparatus that measures a property of a scatterer, including: a light source that supplies illumination light having at least one spectral component; an illumination fiber that propagates, to a distal end thereof, light supplied from a proximal end thereof by the light source and illuminates light onto the scatterer from the distal end; first and second light detection fibers, each outputting, from a proximal end thereof, returned light from the scatterer, the returned light entering from a distal end thereof, the first and second light detection fibers having distal end positions different from each other in a longitudinal direction; a detection unit that detects light output from the proximal ends of the first and second light detection fibers; and a measurement unit that measures a property of the scatterer based on a result of the detection by the detection unit.
