Abstract:
A radiation detector and method and computer program product for detecting radiation. The detector comprises a waveguide structure, a sensing structure comprising a phase change material, an optical transmitter and optical receiver. The optical transmitter transmits an optical sensing signal for receipt at the optical receiver via the waveguide structure. The phase change material comprises a first phase state at a first temperature range and a second phase state at a second temperature range and transitions from the first phase state to the second phase state under exposure of the radiation. The sensing structure is arranged in an evanescent field area of the waveguide structure and provides for an evanescent field of the optical sensing signal a first complex refractive index in the first phase state and a second complex refractive index in the second phase state. The first complex refractive index is different from the second complex refractive index.

An assembly (12) for rapid thermal data acquisition of a sample (10) includes a laser source (14), a light sensing device (26), and a control system (28). The laser source (14) emits a laser beam (16) that is directed at the sample (10), the laser beam (16) including a plurality of pulses (233). The light sensing device (26) senses mid-infrared light from the sample (10), the light sensing device (26) including a pixel array (348). The control system (28) controls the light sensing device (26) to capture a plurality of sequential readouts (402) from the pixel array (348) with a substantially steady periodic readout acquisition rate 405. The control system (28) can generate a spectral cube (13) using information from the readouts (402).

Abstract:
An assembly including an optically excited infrared nondestructive testing active thermography system is disclosed. The optically excited infrared nondestructive testing active thermography system includes one or more illumination sources, at least one first reflector, at least one second reflector and a computing resource. The at least one first reflector is arranged about the one or more illumination sources. The at least one first reflector has a near focal point and a far focal point. The one or more illumination sources is/are positioned at least proximate the near focal point of the at least one first reflector. The at least one second reflector is positioned at least proximate the far focal point. The computing resource is communicatively-coupled to a motor that is coupled to the at least one second reflector for manipulating the at least one second reflector between at least: a first spatial orientation and a second spatial orientation. At least one of the first spatial orientation and the second spatial orientation results in the at least one second reflector reflecting light that originates from the one or more illumination sources. The light is directed toward the at least one second reflector as a result of the light being directly propagated from the one or more illumination sources and reflected by the at least one first reflector. A method is also disclosed.
