Abstract: Provided are a vibration detector and a vibration detecting method, which are power saving, can detect vibration even if the vibration is very weak, and can perform both start-up of the apparatus and collection of data of vibration information by the use of only one sensor. The apparatus includes a vibration detector, a semiconductor switch, a controller and a power supply. The semiconductor switch and the controller are connected to the power supply. The vibration detector detects vibration and consequently generates a vibration voltage. The semiconductor switch includes a voltage divider for generating a bias voltage inside. The semiconductor switch detects a voltage produced by superposing the bias voltage onto the vibration voltage outputted from the vibration detector, and conducts current when the detected voltage is equal to or larger than a certain value. The controller wakes up with the current conducted by the semiconductor switch as a trigger signal.

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.
