abstract="The possibility of using a matrix of sensitive elements on a 12-mm-diameter hyperhemispherical lens in a thermal imager operating in the terahertz range has been studied. Dimensions of a lens region acceptable for arrangement of the matrix, in which the receiver noise temperature varies within 16{\%} of the mean value, are determined to be 3.3{\%} of the lens diameter. Deviations of the main lobe of the directivity pattern are evaluated, which amount to {\textpm}1.25{\textdegree} relative to the direction toward the optimum position of a mixer. The fluctuation sensitivity of the receiver measured in experiment is 0.5 K at a frequency of 300 GHz.",
