Embodiment approach 2

[0110] Next, Embodiment 2 of the present invention will be described. The biological optical measurement system according to Embodiment 2 differs in the configuration of the measurement probe from the configuration of the measurement probe according to Embodiment 1 described above. Specifically, the measurement probe according to Embodiment 2 includes a plurality of contact detection optical fibers. Therefore, the processing executed by the biological optical measurement system according to the second embodiment will be described below after describing the configuration of the measurement probe according to the second embodiment. In addition, the same reference numerals are assigned to the same configurations as those of the bio-optical measurement system 1 according to the above-mentioned first embodiment, and description thereof will be omitted.

Embodiment approach 3

[0154] Next, Embodiment 3 of the present invention will be described. The configuration of the biological optical measurement system according to the third embodiment is different from the configuration of the biological optical measurement system 1 according to the above-mentioned first embodiment. Specifically, the biological optical measurement system according to Embodiment 3 further includes a light source unit for irradiating illumination light for detecting contact between the measurement probe and the object to be measured, and an illumination fiber. Therefore, the configuration of the biological optical measurement system according to Embodiment 3 will be described below. In addition, the same reference numerals are assigned to the same configurations as those of the bio-optical measurement system 1 according to the above-mentioned first embodiment, and description thereof will be omitted.

Abstract

Provided are a measurement probe that is capable of determining whether a front end surface thereof is actually in contact with biological tissue, and a bio-optical measurement system. The measurement probe (3) comprises: an illumination fiber (31); a first light receiving fiber (32), a second light receiving fiber (33), and a third light receiving fiber (34) that receive returning illumination light; and a contact detection fiber (35) that detects contact between the front end surface of a rod lens (38) and biological tissue by receiving returning illumination light. The contact detection fiber (35) is disposed in a position at which the detection area of the contact detection fiber (35) on the front end surface of the rod lens (38), through which illumination light and returning light can pass, is outside the illumination area of the illumination fiber (31).

Description

technical field [0001] The present invention relates to a measuring probe and a biological optical measuring system. The measuring probe can be freely attached to and detached from a biological optical measuring device for measuring optical properties of living tissue. Background technique [0002] Conventionally, there is known a biological optical measurement system that irradiates living tissue with illumination light and estimates properties and states (characteristics) of the living tissue based on measured values ​​of returned light reflected or scattered from the living tissue. Such a living body optical measurement system is constituted by an optical measurement device having a light source for irradiating illumination light to living tissue and a detection unit for detecting return light from a measurement object, and a measurement probe opposite to the measurement probe. The optical measurement device is detachable, irradiates the living tissue with irradiation lig...
