    Abstract: [Object] To obtain interference light having a stronger light intensity, and to more accurately measure a refractive index of a measured object, with a simplified configuration.[Solution Means] A light measurement device 100 includes a phase adjustment unit 120 and a detector 140. The phase adjustment unit 120 outputs reference light E(R) based on object light E1 being light to be obtained by transmission or reflection of light E from a light source with respect to a measured object 200, and signal light E(S) whose phase is adjusted to be different from a phase of signal light. The detector 140 derives a transmission or reflection light intensity distribution or a refractive index of the measured object 200, based on interference light E2 between signal light E(S) and reference light E(R) to be output by the phase adjustment unit 120. An optical axis of light E from a light source is linearly disposed. The phase adjustment unit 120 and the detector 140 are disposed on the optical axis of light E from a light source.

    Abstract: A living body is accurately determined while minimizing increases in the size of a device and increases in the number of components. A living body determination device includes a spectroscopic device 104 that disperses light entering from a pedestal side and outputs the result; a light emission device 101 that emits first light toward the pedestal from a position facing the spectroscopic device 104 with the pedestal therebetween; a light emission device 102 that emits second light toward the pedestal from the spectroscopic device 104 side; an image acquisition device 105 that outputs image information indicating a brightness corresponding to the intensity of the light output by the spectroscopic device 104; and a calculation device 106 that acquires first image information regarding each of the spectra of the first light from the image acquisition device 105, acquires first spectroscopic information on the basis of each of the pieces of first image information, acquires second image information regarding each of the spectra of the second light from the image acquisition device 105, acquires second spectroscopic information on the basis of each of the pieces of second image information, and determines whether or not a measurement target 10a is a living body, based on the first and second spectroscopic information.
