Abstract: The apparatus is for use with a surface and includes a light source, a body and a light production apparatus. The light source includes a plurality of elements for generating light. The body: has a planar base for placement in use on the surface, the base being orientated perpendicular to the receiving axis; defines a sampling aperture communicating with the base and through which the receiving axis passes; encompasses the elements; and is adapted, in combination with the light source and when the sampling aperture is blocked to ambient light, to shield the sensor from ambient light. The light production apparatus is for converting the light of the elements through internal reflection, absorption and filtration into light collimated to impinge upon the base, at the intersection of the base and the receiving axis, at a predetermined angle to the receiving axis.

Abstract: An active remote sensing system is provided with an array of laser diodes that generate light directed to an object having one or more optical wavelengths that include at least one near-infrared wavelength between 700 nanometers and 2500 nanometers. One of the laser diodes pulses with pulse duration of approximately 0.5 to 2 nanoseconds at repetition rate between one kilohertz and about 100 megahertz. A beam splitter receives the laser light, separates the light into a plurality of spatially separated lights and directs the lights to the object. A detection system includes a photodiode array synchronized to the array of laser diodes and performs a time-of-flight measurement by measuring a temporal distribution of photons received from the object. The time-of-flight measurement is combined with images from a camera system, and the remote sensing system is configured to be coupled to a wearable device, a smart phone or a tablet.

Abstract: A wearable device includes a measurement device adapted to be placed on a wrist or ear having a light source with LEDs to measure physiological parameters. The measurement device generates an optical beam having a near infrared wavelength between 700-2500 nanometers by modulating the LEDs, and lenses to deliver the beam to tissue, which reflects the beam to a receiver having spectral filters in front of spatially separated detectors coupled to analog to digital converters that generate at least two receiver outputs. Signal-to-noise ratio of the beam reflected from the tissue is improved by comparing the receiver outputs, and by increasing light intensity from the LEDs. The receiver is synchronized to the modulation of the LEDs and uses a lock-in technique that detects the modulation frequency. The measurement device generates an output signal representing a non-invasive measurement on blood within the tissue.

Abstract: The invention relates to a spectrophotometer, especially a spectrophotometer that can carry out simultaneous analysis at different points on the same sample (4), with a high spatial resolution and without requiring a mechanical system for physical scanning along the sample. This is obtained by the provision of means for processing the light received by the photodetectors (5), said processing means having a correlation wherein each of the photodetectors (5) corresponds to a spatial point on the sample (4).In the case of dark field applications, the present invention ensures the standardization of the data using the same measure.
