Two design techniques for the field of view (FoV) of a resistive bolometer system for the analysis of the total radiated power have been developed. The first technique is a new concept of the resistive bolometer system having multiple apertures to achieve a large viewing angle with one bolometer channel. The second technique is an optimization technique of the bolometer location in the major radial direction to minimize error of the analysis. Both techniques have been examined with a virtual tokamak device. By a FoV designed with both techniques, the total radiation power of several radiation profiles can be determined within 3% error of the analysis with one bolometer channel.
