    Abstract: According to the present invention, a lens adhesive including a compound represented by General Formula 1 is provided. Pol1-Sp1-L1-Ar-L2-Sp2-Pol2  (General Formula 1) In the formula, Ar is an aromatic ring group represented by General Formula 2-2 and the like. In the formula, Z1 and Z2 each represent a hydrogen atom, a methyl group, and the like; A1 and A2 each represent —S— and the like; X represents C(Rz)2 and the like (where Rz is a substituent, and two Rz's may form a ring); L1 and L2 each represent a single bond, —O—, —OC(═O)—, —OC(═O)O—, —OC(═O)NH—, and the like; Sp1 and Sp2 each represent a single bond or a linking group such as a linear alkylene group; Pol1 and Pol2 each represent a hydrogen atom or a polymerizable group; and a compound represented by General Formula 1 has at least one polymerizable group. Using the lens adhesive, it is possible to provide a cemented lens that is unlikely to deteriorate due to light, and an imaging module having high durability.

    Abstract: An object of the present invention is to provide a signal detection system capable of removing noise caused by scattered light or the like and capable of detecting an accurate signal. The problems can be solved by providing a signal detection system including an emitting unit that emits polarized light as measurement light, a retroreflection member that retroreflects the measurement light, and a detecting unit that detects the retroreflected measurement light, in which in the retroreflection member, a reflectance of first polarized light is higher than a reflectance of second polarized light which is polarized light having a property opposite to that of the first polarized light, and at least one of a first condition in which in the measurement light emitted from the emitting unit, an intensity of the first polarized light is higher than an intensity of the second polarized light, or a second condition in which in the detecting unit, a detection sensitivity of the first polarized light is higher than a detection sensitivity of the second polarized light is satisfied.
