Thermal image sensor on rotary shaft

摘要

The sensor thermal image has a group of pyroelectric type heat sensing elements (5) arranged on a line, an optical system (6), a structure (7) for making the pyroelectric type heat sensing element group (5) and the optical system (6) in one body, and a rotary shaft (8) rotate the structure (7). The system obtains a two-dimensional thermal image by using the pyroelectric type heat sensing element group arranged on the line in one-dimensional way.
