The invention provides a measuring sensor and a measuring device. The measurement sensor comprises an emission sensing head which comprises a first lens group and a second lens group which are arranged at an interval, and the first lens group is used for converting first linearly polarized light into first circularly polarized light and transmitting the first circularly polarized light to the second lens group; the second lens group is used for converting the first circularly polarized light into second circularly polarized light and reflecting the second circularly polarized light to the first lens group, the first lens group is also used for reflecting the second circularly polarized light to the second lens group, and the second lens group is also used for converting the second circularly polarized light into second linearly polarized light and transmitting the second linearly polarized light to an object to be measured; and the receiving sensing head is used for receiving the second linearly polarized lig
