Abstract:THz continuum spectral photometry has new and unique applications in different civil
and military areas presenting a number of distinctive advantages on the well known microwaves
or mid- to near-infrared technologies. THz sensing is essential to investigate the emission
mechanisms by high energy particle acceleration processes. Technical challenges appear to
diagnose radiation produced by solar flare burst emissions measured from space as well as
radiation produced by high energy electrons in laboratory accelerators. THz filters and detectors
have been investigated for the construction of solar flare high cadence radiometers to operate
outside the terrestrial atmosphere. Experimental setups have been assembled for testing THz
continuum radiation response from distinct detectors: adapted commercial microbolometer array,
pyroelectric module, and optoacoustic (Golay cell). The results permitted the final design of a THz
double radiometer using Golay cells to be flown in stratosphere balloon missions.
