Micro-Scale Thermal Imaging of Organic and Polymeric Materials with Cooled and Uncooled Infrared Cameras
Figure 2
((A),(B), and (C)) Sequence of the emissivity corrected image of freezing onion-skin cells at minus temperatures under a cooling scan observed with the InSb IR FPA (30 μm detector pitch) equipped with a 7.5 magnification micro lens. ((a), (b), and (c)) Sequence of the emissivity corrected image of freezing leek cells ((a),(b),(c)) at minus temperatures under a cooling scan 0.2 K/s observed with the VOx IR FPA (17 μm detector pitch) equipped with a 2.5 magnification micro lens. After the emissivity correction, temperature of each pixel is calibrated. The temperature is shown in the concentration bar in the left. The signal is captured via NTSC in the time interval as shown in the figures.
