Method and apparatus for detecting defects in a composite is provided. After a ply of material for a workpiece is positioned, thermal energy is applied to a top surface of the ply of material, and a digital thermographic camera captures images of the top surface. A computer processor determines heat characteristics of the top surface to identify regions of the top surface with different heat characteristics. Such different areas are identified as regions that include a defect. The defect regions can be repaired prior to disposing additional plies of material over previously-applied plies.

An electromagnetic wave detection apparatus 10 includes a separator 16, a first detector 17, a switching unit 18, and a second detector 20. The separator 16 is capable of switching between a separation state and a non-separation state. The separator 16 separates incident electromagnetic waves to travel in a first direction d1 and a second direction d2, in the separation state. The first detector 17 detects electromagnetic waves traveling in the first direction d1. The switching unit 18 includes a plurality of switching elements “se”. Each switching element “se” is capable of switching a traveling direction of electromagnetic waves traveling in the second direction d2 between a third direction d3 and a fourth direction d4. The second detector 20 detects electromagnetic waves traveling in the third direction d3.

There is provided a computer implemented method of measuring a temperature of a subject, comprising: receiving a sequence of a plurality of thermal images of a subject captured by a thermal sensor, analyzing the sequence of the plurality of thermal images to identify at least one target thermal image depicting an upper region of a tongue of the subject, analyzing the at least one target thermal image to identify an estimated temperature of the upper region of the tongue, and providing the estimated temperature of the upper region of the tongue.

A method for thermographic analysis of a heat exchanger comprises: applying vibrations to the heat exchanger as a part of a vibration testing process; capturing a thermographic image of at least a portion of the heat exchanger whilst the heat exchanger is undergoing vibrations; analysing the thermographic image; and determining a status of the heat exchanger based on the analysis of the image.

A method of detecting the presence of a product sprayed onto an application surface, in which the product to be applied to the application surface is sprayed onto a target zone of the application surface in pulses. Before spraying the product it is heated to a temperature higher than a predetermined temperature value. After spraying the product, a value of a parameter representing the temperature of the target zone is measured remotely, and the value of that parameter is compared to a reference value of that parameter. A detection installation including pulsed spraying by way of forming part of a device shared with the heating element.

A measurement system includes a cable having a length, a light source, at least one detector, and at least one processor. The light source is operably coupled to the cable and is configured to transmit an optical signal to the cable. The at least one processor is operably coupled to the cable and configured to: receive a scattered signal from the cable responsive to the optical signal transmitted to the cable; map the scattered signal to the length of the cable; and de-convolve a spatial averaging effect of the scattered signal using a weighting profile corresponding to the light source and the cable to generate a distributed property profile defined along the length of the cable.

A cooking temperature sensor having a controller including a thermal imaging camera which identifies at least one food item in a cooking environment. A display is in communication with the controller and the controller transmits data representative of the at least one food item for display. A selection is received in connection with the data and associates a temperature with the at least one food item. The controller monitors a thermal value of the at least one food item and generates an alert indicative of when the temperature is reached for the at least one food item.

A camera assembly for use in medical tracking applications having a range camera and a thermographic camera in a fixed relative position. The range camera is configured to acquire a first image of an object at a first instant of time and a second image at a second instant of time.
