Abstract: A technology is provided that is capable of reducing the size of an apparatus and improving the work environment of surgical operations as compared with those of related-art technologies. The present technology provides an illumination light transmission apparatus having a non-speckle illumination light source configured to radiate a non-speckle illumination light; a speckle illumination light source configured to radiate a speckle illumination light; a fiber bundle configured by a plurality of optical fibers into a bundle; and an optical control block configured to guide at least one of the non-speckle illumination light and the speckle illumination light into the fiber bundle.

Abstract: The flow rate of light scattering fluid is measured more easily and at a higher speed.
A flow rate measuring method according to the present disclosure includes: generating two or more speckle images by continually imaging light scattering fluid to be measured, while defining time shorter than spatial correlation disappearance time corresponding to time in which spatial correlation between speckle patterns generated by the light scattering fluid disappears as exposure time, at a time interval shorter than the spatial correlation disappearance time; and calculating direction and speed of flow of the light scattering fluid from time variation of the speckle patterns between the two or more speckle images, in which the speckle images are imaged by using an imaging device mounted with an area sensor and a pixel group of a part of the area sensor or by using an imaging device mounted with a line sensor.

Abstract: Provided is a measuring apparatus including: a light source unit to emit pulsed laser light used for pump light and Stokes light that excite a molecular vibration of a sample; a Stokes light generating unit to modulate an intensity of the pulsed laser light and to generate Stokes light using the pulsed laser light having the modulated intensity; a time delaying unit to delay the pump light using the pulsed laser light or the Stokes light; a detecting unit to detect, by lock-in detection, light transmitted through the sample irradiated with the pump light and the Stokes light having a controlled time delay amount, or reflected light from the sample; and an arithmetic processing device to perform arithmetic processing on the basis of anti-Stokes light detected by the lock-in detection while controlling the intensity modulation and the time delay amount.
