Abstract: A blood pressure measurement device estimates blood pressure based on first internal pressure of cuff during a first period and Korotkoff sound during the first period or based on the first internal pressure during the first period and first pulse wave during the first period; calculates timings when the first pulse wave satisfies a predetermined condition, a third period between timings, and pressure of first internal pressure during the third period and generates first information where the third period and the pressure are associated; generates blood pressure information where the calculated first information and the estimated blood pressure are associated; and specifies the first information matching or resembling second information generated based on second internal pressure of the cuff during second period and second pulse wave during the second period, and estimates the blood pressure associated with the specified first information as blood pressure during the second period.

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.
