TTG-100 Test Target Generator with BSC-1000 Blackbody System Controller

Photonics MarketplaceThe TTG-100 Test Target Generator is an essential hardware component used when evaluating the performance of complete thermal imaging systems. It may be used as a standalone instrument for making subjective measurements of MRTD and MDTD, or as part of a complete metrology system including a signal acquisition device and the I-SITE^TM software package for evaluating these and other parameters objectively. The recent development of the BSC-1000 Blackbody System Controller has significantly improved the interface between the proven target generator and the user or system computer alike.

The TTG-100 head comprises an extended area variable-temperature source and an ambient-temperature target. In differential mode, the source maintains a precisely-controlled temperature difference with respect to the target. Infrared radiation from the source passes through one or more aperture patterns cut into the target to produce a pattern of thermal contrast in the image plane of imaging system under test. The relationship between the contrast in the image produced and the known temperature difference and spatial frequency of the target pattern can be used to determine the MTRTD and MDTD for the system. When special targets are used with the I-SITE^TM software, several other important imaging system parameters may also be measured.
