Abstract:
PCT No. PCT/GB93/01357 Sec. 371 Date Dec. 23, 1994 Sec. 102(e) Date Dec. 23, 1994 PCT Filed Jun. 29, 1993 PCT Pub. No. WO94/00749 PCT Pub. Date Jan. 6, 1994.Light measurement apparatus includes an elongate member which has at one end thereof light emitter(s) and light detector(s). At least the end of the elongate member that has the light emitter(s) and light detector(s) is surrounded by a resiliently biased sheath. In use, when the elongate member is applied to a surface to take a reading, the sheath defines a light-tight enclosure. A related method for determining intensity and/or color of a colored spot on a surface of a test site uses the light measurement apparatus. The method includes bringing the end of the elongate member into contact with the surface, pressing the resiliently biased sheath towards the surface to define a light-tight enclosure, and measuring the intensity and/or color of the colored spot on the surface.
