Abstract: Techniques are provided to perform flat field correction for infrared cameras using a liquid shutter. Devices and methods provide a focal plane array (FPA) that receives infrared radiation (e.g., thermal infrared radiation) from a scene, and infrared-opaque liquid disposed in a cavity of a liquid shutter housing, and a fluid controller that directs the liquid from a reservoir area of the cavity to a field of view area of the cavity to block the FPA from the infrared radiation. Flat field correction terms may be determined and radiometric calibration may be performed. In one example, a liquid shutter uses voltages to direct liquid. In another example, a liquid shutter uses magnetic fields from electromagnets to direct liquid such as ferrofluid. In another example, a liquid shutter uses electrowetting techniques to direct liquid such as water. In a further example, a liquid shutter uses a pump.

Abstract: Fouling of or damage to an electromagnetic radiation-transparent window can preclude one from obtaining satisfactory images with an image acquisition unit, such as a camera. Certain types of environments may be particularly prone toward promoting fouling or damage, and manual cleaning or repair of an electromagnetic radiation-transparent window may be difficult in some circumstances. These issues may be particularly prevalent when imaging drill cuttings and other solids obtained from a wellbore due to the complex sampling environment in which these solids are often disposed.

Abstract: A wheel alignment system includes a side-to-side reference including an active reference pod and a passive reference pod disposed on opposite sides of the vehicle. The active reference pod includes a reference image sensor fixedly attached to a reference target, for mounting on a first side of the vehicle such that the reference image sensor produces image data including a perspective representation of the passive reference pod disposed on a second/opposite side of the vehicle. In operation, alignment cameras on the opposite sides of the vehicle capture perspective representations of targets mounted to vehicle wheels and of targets of the active and passive reference pods. A computer processes the image data to compute an alignment measurement of the vehicle based on a spatial relationship between the active reference pod and the passive reference pod determined according to the image data produced by the reference image sensor.
