The development of photochromic Computer Generated Holograms (CGHs) to test any complex optics, such as aspheres and free-form optics, is described. A thermally irreversible photochromic polyurethane has been synthesized to give good thin films with a strong modulation of the optical transmission. The photochromic CGH has been tested with a simple interferometrical configuration showing promising results. The use of photochromic CGHs provides advantages over standard technologies, as rewritability and self developing.
描述了用于测试任何复杂光学器件（如非球面和自由曲面光学器件）的光致变色计算机生成全息图（CGH）的开发。已合成一种热不可逆光致变色聚氨酯，以制备具有强光透射调制的优质薄膜。光致变色CGH已通过简单的干涉配置进行测试，结果很有前景。光致变色CGH的使用相对于标准技术具有优势，如可重写性和自显影性。
