Abstract:
On-board non-uniformity correction calibration methods for a microbolometer focal plane array in a thermal camera are disclosed. The methods include performing first calculations in the processor unit of the thermal camera to generate and apply a set of coarse correction bias voltages to the detector elements. The method also includes performing calculations in the external computer based on image data collected by the thermal camera with the coarse correction bias voltages applied to the detector elements to generate a set of fine correction bias voltages. The method also includes downloading the fine correction bias voltages to the thermal camera and applying the fine correction voltages to the detector elements to establish a fine calibration of the microbolometer focal plane array.
Abstract:
An additive manufacturing temperature controller/temperature sensor uses one or more spectrophotometric sensors to monitor temperature of successive layers and preferably localized sections of successive layers of a melt pool, and transients thereof, of an object being generated for the purpose of dynamic control of the additive manufacturing device and/or quality control of the generated object manufactured with the additive manufacturing device. Generally, the additive manufacturing temperature controller/sensor apparatus monitors temperature of a section of the object during manufacture as a function of wavelength, time, position, and/or angle to determine melt extent in terms of radius and/or depth.
Abstract:
Temperature monitoring systems for data centers include a plurality of ceiling-mounted infrared sensor arrays. Each infrared sensor array includes a two-dimensional array of infrared emission sensors, and at least some of the infrared emission sensors have field of view patterns that project onto aisle faces of equipment racks that are mounted in rows in the data center. These systems may further include a controller that is remote from at least some of the infrared sensor arrays and that is in communications with the infrared sensor arrays, the controller configured to provide a two-dimensional thermal map of the aisle faces of the equipment racks based at least in part on temperature data received from the infrared sensor arrays.
Abstract:
A sight attachable to a weapon and comprising an objective lens, an image display, and a digital reticle. The objective lens focuses infrared light received from a scene onto a thermal imager, which is comprised of a focal plane array that detects infrared radiation in the scene focused by the lens. The image display is in signal communication with the thermal imager and provides an image of the received infrared light from the scene. The image rendered by the display is visible to the user. The digital reticle is rendered on the display and provides an aim point of the weapon upon a target in the scene. The image of the scene and superimposed reticle are directly viewable by a user with the aim point of the weapon upon the target being maintained constant over a range of viewing angles that depart from a viewing angle perpendicular to the display.
