摘要：Optical displacement sensor may possess light-emitting element(s) forprojecting light onto distance measurement target(s) , and light-receiving element(s)capable of receiving light reflected from distance measurement target(s) and disposedsuch that light-receiving surface(s) thereof is or are substantially perpendicular to optical
axis or axes Rof projected light. Furthermore, such optical displacement sensor(s) may beequipped with slit(s) capable of narrowing light beam(s) projected toward distancemeasurement target(s) , and slit(s) capable of narrowing light reflected from distancemeasurement target(s)
