Abstract
This presentation explores potential application of antenna-pair coupled micro-bolometers in IR beam wavefront metrology. It describes an array configuration of such bolometers and a method for extracting a 1-D whole complex field information from its response. In addition, it discusses the requirements on the antenna-pair spacing and the spacing between the pair elements of the array configuration for extracting the complex field information. A numerical simulation based on the transmission line theory shows the effectiveness of such an array in recording the complex field spatial information of incident radiation; especially, it shows that the wavefront phase information can be extracted without the knowledge of the single antenna pattern. The discussions here should also be valid for antenna-pair coupled bolometers working at longer wavelengths.
