全息波带板是用全息照相方法制得的波带板,是全息透镜的一种。它是具有折射光学透镜成象特性的一种平面型透镜(全息图),它较之光学透镜具有薄膜型、重量轻、口径大、结构紧凑、复制容易、成本低廉等特点。实际上,全息波带板是一块类同于圆光栅的全息图,它是制取波带板中最简单又是最精确的一种,从而使它的应用成为可能。 The hologram plate is a plate made of hologram method, which is a kind of holographic lens. It is a planar lens (hologram) with imaging properties of refracting optical lens, which is thinner than optical lens, light weight, large caliber, compact structure, easy to copy, low cost and so on. In fact, the hologram plate is a hologram similar to a circular grating, which is the easiest and most accurate one to make the strip plate, making its application possible.
