Abstract: A sensor package includes a substrate, a light sensor disposed on the substrate, at least one optical filter disposed on the light sensor, and an optical functional layer that is light-permeable, is disposed on the substrate, covers the light sensor and the optical filter, and includes multiple light-scattering particles. The light sensor has a light receiving region, and receives light through the light receiving region. The optical filter covers the light receiving region. When the light passes through the optical filter within an incident angle range and is received by the light receiving region, the light sensor responds to a wavelength range of the light, and a response spectrum is obtained. Within the incident angle range, an absolute value of an offset measured at a crest of a waveform of the response spectrum is less than or equal to 10 nm. An electronic device is also provided.

Abstract: A system and method for verifying a desired alignment of an ultraviolet (UV) lamp with respect to a target component include a housing. A UV sensor is coupled to the housing. The UV sensor is configured to detect UV light emitted from one or more UV light emitters of the UV lamp and output one or more signals indicative of the UV light. A UV recorder is coupled to the housing. The UV recorder is in communication with the UV sensor. The UV recorder is configured to receive the one or more signals from the UV sensor and store data regarding the one or more signals.

Abstract: The present disclosure relates to a method for photometrical charting of a light source (Q, 3) clamped within a positioning device (1) and stationary relative to an object coordinate system (T) by means of a luminance density measurement camera (4) arranged stationary relative to a world coordinate system (W), wherein the light source (Q, 3) is moved between a first actual measurement position (P1′) and at least one further actual measurement position (P2′ to P5′) along a kinematic chain of the positioning device (1) within the world coordinate system (W), wherein a luminance density measurement image (81 to 85) describing the spatial distribution of a photometric characteristic within a measurement surface is recorded by means of the luminance density measurement camera (4) in each actual measurement position (P1′ to P5′) with the light source (Q, 3) turned on, and wherein the position and/or orientation of the object coordinate system (T) relative to the world coordinate system (W) is recorded in each actual measurement position (P1′ to P5′) in direct reference to the world coordinate system (W) without reference to the kinematic chain of the positioning device (1). Moreover, the present disclosure relates to the use of such a method for photometric charting of a headlight (3).

Abstract: Laser warning systems are provided for providing an alert when exposure to laser light sources is detected. The system includes a colloidal quantum dot detector module including a colloidal quantum dot photodetector and a processor coupled to the colloidal quantum dot detector module. The system detects interference patterns generated in the colloidal quantum dot detector module by light illuminating the laser warning system and determines if the light illuminating the laser warning systems is laser light based on a magnitude of interference infringes generated by the light illuminating the laser warning system.

Abstract: A system for stiffening a structure has at least one pair of tie rods (3), each tie rod (3) of the pair of tie rods (3) having a first end (4) fastened to the structure (2) and a second end (5), and at least one device (6) for tensioning the tie rods (3) having a deformable linking element (7) fastened to the second end (5) of each tie rod (3) so as to connect the tie rods (3). An actuator (10) is configured to deform the linking element (7) so as to make it pass from an inactive configuration in which the tie rods (3) are in a first state of tension to an active configuration in which the tie rods (3) are in a second state of tension, different than the first state of tension.

Abstract: A system for determining the profile of a laser beam includes a detector having a thermochromic liquid crystal film (TLCF) in thermal communication with a heat spreader and a thermoelectric cooler. The liquid crystal film has a thermochromic response such that heating of the film by a received laser beam creates a detectable color response at the film. The system also includes an image sensor and a controller configured to output an operating current for the TEC and receive images from the sensor. The system can selectively vary the temperature set point of the TEC to change the steady state temperature of the TLCF to examine the full intensity profile of the received beam even when the temperature response bandwidth of the TLCF is too narrow to display the full beam profile in a single color spot.
