Abstract: A color measurement apparatus includes at least one illuminator, an imager, and circuitry. The circuitry is configured to normalize each pixel included in an imaging region of one of the spectral reflectance images of the measurement target irradiated with light at a specific illumination angle of the plurality of illumination angles, with one of the spectral reflectance images of the reference object irradiated with light at the specific illumination angle, for each of the plurality of illumination angles so as to generate normalized spectral reflectance images of the measurement target. The circuitry further calculates a numerical value of at least one color for each pixel of the normalized spectral reflectance images of the measurement target, for respective ones of the plurality of illumination angles, to measure color of the surface of the measurement target.

Abstract: A radiation measuring device for measuring electromagnetic radiation originating from an external source. The radiation measuring device includes, a spectrometer, a pyranometer, a pyrgeometer, a diffuser, and a control unit. The spectrometer and a pyranometer are positioned in a sensor zone of a housing of the radiation measuring device. The spectrometer measures visible shortwave radiation and near-infrared shortwave radiation received at the sensor zone. The pyranometer measures shortwave radiation received at the sensor zone. The pyrgeometer is positioned in another sensor zone of the housing and measures longwave radiation received at the other sensor zone. The control unit receives radiation measurements from the spectrometer, pyranometer, and pyrgeometer. A corrected amount of radiation received at the sensor zones of the radiation measuring device is determined from the received radiation measurements. Other embodiments are described and claimed.

Abstract: A protective sheath having a closed end and an open end is sized to receive a hand held spectrometer. The spectrometer can be placed in the sheath to calibrate the spectrometer and to measure samples. In a calibration orientation, an optical head of the spectrometer can be oriented toward the closed end of the sheath where a calibration material is located. In a measurement orientation, the optical head of the spectrometer can be oriented toward the open end of the sheath in order to measure a sample. To change the orientation, the spectrometer can be removed from the sheath container and placed in the sheath container with the calibration orientation or the measurement orientation. Accessory container covers can be provided and placed on the open end of the sheath with samples placed therein in order to provide improved measurements.

Abstract: An optical head for receiving an incident light is provided. The optical head comprises a reflective diffuser and a reflector disposed to face the reflective diffuser. The reflective diffuser is disposed in an optical path of the incident light and shields the reflector from the incident light. The reflective diffuser converts the incident light to scattered light having a Lambertian pattern. The reflector has an optical output section that transmits the scattered light and a reflective section that reflects the scattered light to the reflective diffuser and/or the other portions of the reflective sections. An optical system using the optical head is also provided.

Abstract: A system of measuring hemoglobin and bilirubin parameters in a whole blood sample using optical absorbance. The system includes an optical-sample module, a spectrometer module, an optical fiber module optically connecting the optical-sample module to the spectrometer module, and a processor module. The optical-sample module has a light-emitting module having a LED light source, a cuvette and a calibrating-light module. The processor module receives and processes an electrical signal from the spectrometer module and transforms the electrical signal into an output signal useable for displaying and reporting hemoglobin parameter values and/or total bilirubin parameter values for the whole blood sample.

Abstract: A system and method of optical spectrum analysis that circumvents the trade-off between resolution and sensitivity by combining two spectral measurements: a first spectrum (102) from first spectral measurement means (240), having high resolution and low sensitivity; and a second spectrum (103) from second spectral measurement means (220), having lower resolution but higher resolution. The input of the of the first spectral measurement means (240) is amplified by an optical amplifier (230), being the effects induced by said amplifier (230) on the first spectrum (102) corrected at processing means (270) by comparison with the second spectrum (103).
