Abstract: An optical sensor. The optical sensor comprises a substrate, a Fabry-Perot interferometer, and first and second photodetectors. The Fabry-Perot interferometer comprises a first mirror and a second mirror, and is mounted on the substrate such that light is transmitted through the interferometer to the substrate. The first and second photodetectors are configured to detect light transmitted through the etalon and the substrate. The first photodetector is sensitive to a first wavelength range, and the second photodetector is sensitive to a second wavelength range, and wherein the first and second wavelength ranges each correspond to a different mode of the interferometer.

Abstract: Disclosed are methods and devices for calibration in the field of optical sensors, e.g. characterizing and calibrating an optical sensor chip. In order to address complexity of sensor data with high accuracy the optical sensor, e.g. an optical sensor is not provided as an already calibrated unit. Rather, sensor response data may be recorded in a defined or standardized environment, e.g. at a production line, and with high precision. This high standard sensor response data can be obtained on a per device basis and, thus, is referenced with an unambiguous chip identification number, chip ID. The sensor data is complemented with a dedicated calibration algorithm which can be tailor-made to fit the optical sensor or the optical sensor chip. In order to retrieve the sensor response data and the calibration algorithm both can be made available by means of the chip ID, for example.

Abstract: A concealment component for an optical sensor device includes an optical filter and one or more diffusive optical structures. The one or more diffusive optical structures are configured to distribute light in a diffused pattern on an input surface of the optical filter. The optical filter is configured to pass a first set of light beams, of the light distributed in the diffused pattern on the input surface of the optical filter, that are associated with a particular wavelength range, and prevent a second set of light beams, of the light distributed in the diffused pattern on the input surface of the optical filter, that are not associated with the particular wavelength range, from passing. Preventing the second set of light beams from passing is to cause the second set of light beams to be directed away from or absorbed by the concealment component in a concealment pattern.

Abstract: An optical system comprises a wearable device for measuring one or more physiological parameters. The physiological parameters may change in response to stretching of the hand or movement of fingers or thumb of the user, or the parameters may be related to blood constituents or blood flow. The wearable device comprises a light source with a plurality of semiconductor diodes and a detection system that measures reflected light from tissue comprising skin. The semiconductor diodes may be light emitting diodes or laser diodes. The signal to noise ratio for the output signal may be improved by synchronizing the detection system to the light source, increasing light intensity of at least one of the plurality of semiconductor diodes from an initial light intensity, and using change detection that compares light on versus light off for the detection system output. The wearable device is also configured to identify an object.

Abstract: A multispectral sensor array can include a combination of ranging sensor channels (e.g., LIDAR sensor channels) and ambient-light sensor channels tuned to detect ambient light having a channel-specific property (e.g., color). The sensor channels can be arranged and spaced to provide multispectral images of a field of view in which the multispectral images from different sensors are inherently aligned with each other to define an array of multispectral image pixels. Various optical elements can be provided to facilitate imaging operations. Light ranging/imaging systems incorporating multispectral sensor arrays can operate in rotating and/or static modes.

Abstract: A bidirectional reflectance distribution function (BRDF) measurement system and method, an electronic device, and a storage medium. The BRDF measurement system includes: a blackbody, a spectroradiometer and a controller; where in case that the blackbody is heated to a target temperature, it undergoes a solid-liquid phase change; the spectroradiometer is used to measure the blackbody and transmit a first measurement signal to the controller, and in case that the blackbody irradiates a to-be-measured point on a sample surface, the spectroradiometer is further used to measure radiation from the to-be-measured point, and transmit a second measurement signal to the controller; and the controller is used to obtain a BRDF of the to-be-measured point based on the first measurement signal, the second measurement signal, the target geometric relationship, a target mapping relationship and a dimension parameter of the blackbody.

Abstract: The present invention is a multi-spectral digital autocollimator system featuring a diverse range of capabilities. It comprises a multi-spectral light source spanning from deep UV to Far-IR (8-12 microns), a collimating mirror, a unique optical beam splitting lens, and an imaging device designed to detect the light deviation caused by the multi-spectral light source. The system projects the light through a specially designed cross target, generating visible light, and this cross target can be heated or cooled to create a high-quality black body cross. The resulting light is then reflected back from an examined reflective object and captured by the imaging device. An appropriate thermal camera is strategically positioned after the optical beam splitting lens to analyze the thermal properties of the black body cross. The primary objective of this invention is to offer a precise and multi-spectral digital autocollimator capable of facilitating optical alignment with different spectral devices.
