BLOCKER DEVICE FOR ELIMINATING SPECULAR REFLECTANCE FROM A DIFFUSE REFLECTION SPECTRUM

Diffuse Reflectance Spectroscopy

A spectroscopy system separates the diffuse reflectance component of a reflectance spectrum from the specular reflectance component using a remote field stop filter. The surface of the sample is placed at a focal plane of an optical system. The optical system forms an image on the surface of the sample that includes an image of the remote field stop filter. The optical system images the surface of the sample onto either the same or another remote field stop. Energy reflected from the surface of the sample which is in focus at the remote field stop retains the image information about the image of the filter, whereas energy reflected from below the surface of the sample does not necessarily retain image information about the image of the filter. Since the energy from the surface of the sample is specularly reflected and the energy from below the surface is diffusely reflected, the specular component of the reflectance spectrum is spatially separate from some of the diffuse reflection component ...

Apparatus to measure particle mobility in solution with scattered and unscattered light

A method and apparatus are disclosed for measurement of the electrophoretic mobility of particles in solution. A sample is placed in a cell containing two electrodes that apply an alternating electric field. A monochromatic light beam passes through the sample.

The signal from each is demodulated to provide a measurement of the electrophoretic mobility of the scattering particles. Each detector element provides a simultaneous independent measurement, increasing the amount of information which results in increased sensitivity, extending mobility measurements to particles below one nanometer while reducing the required concentration and electric field.

The first window and the second window may be optically coupled via the cavity, and the shell may prohibit optical coupling between the first window and the second window through the shell.

Optical inspection method and apparatus

Apparatus for optical inspection of particulate material such as diamond abrasive comprises a body (1), an open sample container (25) which can rise and fall in the body, a reference member (71) above the container, mounted in a removable compaction head (9) of which the height relative to the body is fixed, and an optical inspection head (11) mountable on the body in place of compaction head. The container is raised into contact with the reference member so that the surface of the sample is levelled and placed at a predetermined height. The compaction head is then removed and replaced by the optical inspection head. Consequently, the sample surface is always presented to the optical inspection head in a predetermined relationship and in particular at a predetermined height.

进行唾液或流体‑唾液混合物的光学分析，以检查唾液或流体‑唾液混合物是否包含血液，从而允许确定人是否患有齿龈炎或影响牙龈健康的其它病症。检测并分析从包含唾液的代表性流体体积(23)接收的光。该分析涉及仅针对光的单个波长，特别是与血液成分的高吸收相关联的波长，确定由光接收单元(25)接收的光的至少一个测量值。在这一方面，如果光接收单元(25)被配置为接收从流体体积(23)反射回的光，这是实用的。例如，在人口腔中涉及牙龈搅动效果的动作发生期间或之后，可以实时地执行光学分析。
