Abstract: An apparatus and a method for online and real-time detection of a temperature of an epitaxial wafer (4) belong to the technical field of semiconductor detection. The apparatus comprises a MOCVD reaction chamber (1), a light source (6), a beam splitter (7), a reference light detector (8), a reflected light detector (9) and a data acquisition unit (10). The method, on the basis of the apparatus, can obtain a thermal radiation attenuation factor caused by a coating of a reactor chamber window and a reflectance attenuation factor caused by the coating of the reactor chamber window for the epitaxial wafer (4). The apparatus and method can eliminate influence of the coating of the reactor chamber window on an online and real-time temperature detection value, thereby improving the accuracy of the online and real-time temperature detection value.

Abstract: An occupant detection system may detect a state of an occupant in a vehicle compartment. The occupant detection system may photograph the vehicle compartment and generate an image. The occupant detection system may change an attitude in order to change a position of an imaging region within the vehicle compartment. The occupant detection system may estimate the attitude based on information included in the image and control an operation based on the estimated attitude. The sensor may be provided by an infrared temperature sensor. The image may be provided by a thermal image showing a temperature distribution of the vehicle compartment. The occupant detection system may store a correspondence relationship between a position of a specific temperature boundary included in the thermal image and the attitude. The occupant detection system may estimate the attitude based on the correspondence relationship.

Abstract: A photodiode comprising a photoactive spinel oxide layer is described. This photoactive spinel oxide layer forms a contact with both a light absorption layer of quantum dots, quantum wires, or quantum rods, and an inorganic substrate layer. In some embodiments, the inorganic substrate layer and the photoactive spinel oxide layer form an isotype junction. Methods of characterizing the photodiode are provided and demonstrate commercially relevant electrical and optoelectronic properties, particularly the ability to operate as a photodetector with a high photosensitivity. An economical process for preparing the photodiode is provided as well as applications.

Abstract: A method comprises capturing outputs of a VLC and an infrared array sensor (IAS). A memory includes a calibration based on a position of a laser pointer relative to the IAS. The method includes the laser pointer outputting a light beam to produce a laser dot on a target. The output of the VLC includes a representation of the laser dot. The output of the IAS includes values indicative of infrared radiation from the target. The method includes determining a temperature based on a portion of the values indicative of infrared radiation from the target. The portion of the values includes values associated with a portion of the target at which the laser dot is produced. The method includes displaying, on the display, the output of the VLC and the temperature. Displaying the output of the VLC includes displaying a visible light image showing the laser dot and at least a portion of the target.

Abstract: A method includes capturing and scaling VLC and an IAS outputs to generate a scaled VLC output and a scaled thermal output (STO), aligning the scaled VLC output to the STO to generate an aligned image based on the scaled VLC output and the STO, determining alignment value(s) based on the aligned image, a laser pointer outputting a light beam to produce a laser dot on a target, and capturing a further output of the VLC. The method includes displaying the further output of the VLC (including a representation of the laser dot (RLD)), and an alignment marker, shifting the alignment marker and/or the RLD to a common position; determining coordinate(s) of the output of the IAS based on coordinate(s) of the further output of the VLC where the alignment marker and the RLD are shown at the common position; and storing the coordinate(s) of the output of the IAS.

Each of the at least two optical channels can be positioned to transfer IR radiation incident on the optical system towards the optical FPA. The system can include a processing unit containing a processor that can be configured to acquire multispectral optical data representing said target species from the IR radiation received at the optical FPA.
