Abstract： |
The disclosed FT optical system comprises: from input surface to frequency-spectrum surface, a first lens with positive focal power included a first falcate positive/negative lens with convex opposite surface, a second lens with positive focal power included at least a couple of lens, and a thirst lens with negative focal power included a second falcate positive lens and a couple of negative lens. It also provides a holographic information storage FT optical system with one front FT system and one back inverse FT system. |
