Abstract: A correction LED is provided to illuminate a light receiving sensor array, and a calculation controlling circuit calculates correction values at the respective illuminance levels based on sensor output levels expected at the respective illuminance levels and actual sensor output levels while successively turning the correction LED on at a plurality of illuminance levels whose illuminance ratios are at least known, and corrects a sensor output level by the corresponding correction value to obtain a measurement output at the time of an actual measurement. The discontinuity of an input/output characteristic resulting from the switching of gains of an amplifier for amplifying a photocurrent and the non-linearity caused by the saturation of the photoelectrically converting characteristic of the optical sensor and the exponential characteristics of the optical sensor and the amplifier can be corrected without employing a large-scale construction such as a bench. The non-linearity can be highly precisely and efficiently corrected in a measuring apparatus realized as a spectral luminometer or a spectral colorimeter without requiring a special facility.

Abstract: In a medical pulse oximetry sensor (10) at least two light emitting diodes (16, 18) are disposed to emit red light and infrared light through a portion of a subject's anatomy with a typically high oxygenated blood throughput. Typically, this area is also relatively narrow, to allow the light to pass through the area with acceptable attenuation, such as a finger or an earlobe. Light emitted from the LEDs (16, 18) is incumbent upon an integrated circuit (22) printed from a single CMOS substrate (21). The integrated circuit (22) includes all preprocessing and post-processing elements needed to convert the detected light signals into a pulse oximetry measurement. These elements include a photodetector (20), a photo pre-amplifier (40), a sampler/holder (42), an analog to digital converter (44), a microprocessor (46) a rangefinder (48), a timing control circuit (50) and an LED control circuit (52). By integrating all pre and post processing functions into the carriage housing (12), the system becomes more efficient, less expensive to manufacture, and more robust to ambient light and x-ray radiation.

Abstract: A small and inexpensive, noninvasive bone density measuring device is provided. A measuring part of the bone density measuring device is constituted by a light emitter 120, which emits near-infrared light, and a light receiver 130, which receives light via a bone of a measuring subject, arranged in a holder 110. Bone density is measured by inserting an arm, for example, in the holder 110 and measuring light absorption (absorbance) by the arm bone. The light emitter 120 and the light receiver 130 are connected to a control unit 140. The control unit 140 controls the light emitter 120 to emit light, inputs a measured value from the light receiver 130, and displays it as bone density. In order to remove the influence of light from the background or difference in bone thickness, ratio of absorbance between two wavelengths is preferably employed. In order to obtain light of twowavelengths, use ofasingle light receiving element is possible by making two light emitting elements (LEDs) alternately emit light even in the case of using two light emitting elements.
