17 July 2000 T-CAT: a new thermal camera acuity tester
Author Affiliations +
T-CAT (Thermal Camera Acuity Tester) is a thermal `eye chart' for measuring the spatial resolution (`sensor acuity') of thermal imaging systems. It is a small, portable system,, that is used in a similar way as the optometrists' visual acuity charts. The design is an implementation of the TOD (Triangle Orientation Discrimination) method for Electro-Optic sensor characterization that has recently been introduced. The purpose of the T-CAT is do quick and easy assessments of thermal imager performance, e.g. for routine testing such as go/nogo decisions. T-CAT measures system performance including the human observer, which is still the best way to assess actual field performance of an imaging device.
