Abstract
A probe unit (30) of this optical measurement device (100) includes a base member (31) rotatable about a central axis (80), a light-transmitting probe (32) and a light-receiving probe (33) protruding in a first direction from the base member, and a plurality of pin members (34) for parting hairs, the plurality of pin members protruding in the first direction from the base member. The plurality of pin members is inclined obliquely at least either in a direction toward a central axis side of the base member or in a circumferential direction about the central axis of the base member.
Claims13
An optical measurement device comprising:
- a device main body configured to irradiate a head surface of a head of a subject with measurement light via a light-transmitting probe and detect the measurement light emitted from the head surface by way of an inside of the head via a light-receiving probe;
- a holder configured to be attached to the head of the subject;
- and
- a probe unit held by the holder,
- wherein the probe unit includes:
- a base member rotatably held by the holder about a central axis;
- the light-transmitting probe protruding from the base member in a first direction toward the head surface;
- the light-receiving probe protruding from the base member in the first direction;
- and
- a plurality of linear pin members, each protruding linearly from the base member in the first direction for parting hairs of the head surface,
- wherein a central axis line of each linear pin member of the plurality of linear pin members is inclined obliquely at least either in a direction toward a central axis of the base member or in a circumferential direction about the central axis.
A probe holder set for an optical measurement device comprising:
- a holder configured to be attached to a head of a subject;
- and
- a probe unit held by the holder,
- wherein the probe unit includes:
- a base member rotatably held by the holder about a central axis;
- a light-transmitting probe protruding from the base member in a first direction toward a head surface of the head of the subject;
- a light-receiving probe protruding from the base member in the first direction;
- and
- a plurality of linear pin members each protruding linearly from the base member in the first direction for parting hairs of the head surface, and
- wherein a central axis line of each linear pin member of the plurality of linear pin members is inclined obliquely at least either in a direction toward a central axis of the base member or in a circumferential direction about the central axis, and
- wherein the probe holder set is configured to irradiate the head surface of the subject with a measurement light via the light-transmitting probe and detect the measurement light emitted from the head surface by way of an inside of the head via the light-receiving probe.
