BOLOMETRIC-TYPE ACTINOMETRIC RECEIVER Russian patent published in 2012 - IPC G01J5/20 G01W1/12 

FIELD: physics.

SUBSTANCE: receiver has basic and additional sensitive elements. Both elements lie on a common dielectric substrate with low coefficient of thermal conductivity and have the same shape of a hollow spherical segment, and are also made from an alloy with a shape memory effect. The basic element is black. The additional element has a polished surface. Sectional planes of the sphere, which form hollow spherical segments, are parallel to the plane of the dielectric substrate. The arched part (peak) of the elements faces the vertex. The line which connects the peaks of the elements is directed along the north-south direction. The distance between the peaks is at least twice the diameter of the base of the spherical segment.

EFFECT: high sensitivity.
