  • Publication number: 20180058938
    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.

    Abstract: A light source unit is provided with a first light source, a second light source, and a third light source that emit red light, green light, and blue light, respectively, as illumination light. A light source controller controls emission intensity and emission timing of the illumination light to make an emission period of the red light longer than an emission period of each of the green light and the blue light. An image sensor is capable of separately receiving the light of each color reflected from an object of interest irradiated with the illumination light and capable of separately changing a light-receiving period of the light of each color. An imaging controller makes the light-receiving period of at least the red light coincide with the emission period of the red light.
