Abstract: A sensor (10) for measuring reflective, transmissive, or self-luminous samples, comprises a plurality of light sources (18), where each of the ligh t sources emit light of a substantially different wavelength band spaced in th e visible spectrum; a reference channel photodetector (20); a sample channel photodectector (22); an optical cap (26) adapted to direct a first portion o f the light emitted by each of the light sources to the reference channel photodetector (20); a reflector cone for directing a second portion of the light emitted by each of the light sources to the sample; and a receptor pie ce (36) for directing the diffuse portion of the light reflected from the sampl e to the sample channel photodetector (22). The sensor (10) is preferably incorporated into a hand-held "mouse" device, which includes an area on its top surface for seating an index finger of the human hand.

Abstract: A sensor for measuring reflective, transmissive, or self-luminous samples, comprises a plurality of light sources, where each of the light sources emit light of a substantially different wavelength band spaced in the visible spectrum; a reference channel photodetector; a sample channel photodetector; an optical cap adapted to direct a first portion of the light emitted by each of the light sources to the reference channel photodetector, a reflector cone for directing a second portion of the light emitted by each of the light sources to the sample; and a receptor piece for directing the diffuse portion of the light reflected from the sample to the sample channel photodetector. Preferably, the reference channel and sample channel photodetectors are identical devices and are mounted back-to-back to share environmental characteristics, and in turn, minimize the variation between their respective responses. The sensor is preferably incorporated into a hand-held "mouse" device, which includes an area on its top surface for seating an index finger of the human hand. Positioned within this area is a pressure-activated switch that is operatively coupled to the sensor circuitry for performing the various readings. And the sensor is preferably mounted into the mouse device such that the focal aperture of the downward pointing reflector cone is in axial alignment with the pressure-activated switch. Accordingly, a user will be able to use the mouse to "point" with his or her index finger to an area of the sample surface, and will then simply press the switch using the same index finger.

Abstract translation: 用于测量反射，透射或自发光样品的传感器包括多个光源，其中每个光源发射在可见光谱中间隔开的基本不同的波长带的光; 参考通道光电检测器; 样品通道光电检测器; 光学帽，适于将由每个光源发射的光的第一部分引导到参考通道光电检测器;反射器锥体，用于将由每个光源发射的光的第二部分引导到样品; 以及用于将从样品反射的光的漫射部分引导到样品通道光电检测器的受体片。 优选地，参考通道和采样通道光电检测器是相同的装置，并且背对背地安装以分享环境特性，并且进而使其各自响应之间的变化最小化。 传感器优选地结合到手持式“鼠标”装置中，该装置包括在其顶部表面上用于放置人的食指的区域。 位于该区域内的是压力激活的开关，其可操作地耦合到传感器电路，用于执行各种读数。 并且传感器优选地安装到鼠标装置中，使得向下指示反射器锥体的焦点孔与压力启动的开关轴向对准。 因此，用户将能够使用鼠标将他或她的食指“指向”到样品表面的区域，然后将简单地使用相同的食指按压开关。
