Abstract:
An inventory management system (400) comprises: an optical laminated body that is disposed on the front surface of a storage structure (100) in which a product is stored and that has a linear transmittance of 40% or more for light at a wavelength in at least one section in a range between 760 nm-2000 nm; and infrared detection devices (410a, 410b) positioned so as to receive infrared rays reflected by a product through the optical laminated body. The optical laminated body is an optical filter layer (110) that diffuses and reflects visible light, said optical filter layer (110) having a matrix and microparticles that are light scattering bodies dispersed in the matrix, and having a linear transmittance of 60% or more for light at a wavelength in at least one section in a range from 760 nm-2000 nm.
