LIQUID CRYSTAL LENS OPTICAL BODY AND OPTICAL INFORMATION READING DEVICE

WIPO Patent Application WO/2012/090898

A1

Provided is a liquid crystal lens optical body permitting a rapid response. In a liquid crystal lens optical body (30), a first liquid crystal lens (31A) in which a liquid crystal layer (32A) is flanked by electrodes (33A, 34A) and the alignment state of liquid crystal molecules is controlled to change the optical power in accordance with a signal inputted to an electrode, and a second liquid crystal lens (31B) in which a liquid crystal layer (32B) is flanked by electrodes (33B, 34B) and the alignment state of liquid crystal molecules is controlled to change the optical power in accordance with a signal inputted to an electrode, are provided on an optical axis. In each of the liquid crystal lenses, the response characteristic to an inputted signal when a transition is made from a state of high optical power to a state of low optical power is different from the response characteristic when a transition is made from a state of low optical power to a state of high optical power.
