Abstract

This review discusses the current state of knowledge regarding the phenomenon called two-photon vision. It involves the visual perception of pulsed infrared beams in the range of 850–1200 nm as having colors corresponding to one-half of the IR wavelengths. It is caused by two-photon absorption (TPA), which occurs when the visual photopigment interacts simultaneously with two infrared photons.

The physical mechanism of TPA is described, and implications about the efficiency of the process are considered. The spectral range of two-photon vision is defined, along with a detailed discussion of the known differences in color perception between normal and two-photon vision. The quadratic dependence of the luminance of two-photon stimuli on the power of the stimulating beam is also explained. Examples of recording two-photon vision in the retinas of mice and monkeys are provided from the literature. Finally, applications of two-photon vision are discussed, particularly two-photon microperimetry, which has been under development for several years; and the potential advantages of two-photon retinal displays are explained.

双光子视觉 - 用红外线观察颜色

本综述讨论了有关双光子视觉现象的知识现状。双光子视觉是指视觉感知到 850-1200 纳米范围内的脉冲红外线光束具有与二分之一红外线波长相对应的颜色。它是由双光子吸收（TPA）引起的，当视觉光色素同时与两个红外光子相互作用时，就会发生双光子吸收。对双光子视觉的光谱范围进行了定义，并详细讨论了正常视觉和双光子视觉在色彩感知方面的已知差异。此外，还解释了双光子刺激亮度与刺激光束功率的二次关系。文献中提供了在小鼠和猴子视网膜上记录双光子视觉的例子。最后，讨论了双光子视觉的应用，特别是双光子显微瞳孔测量法，该技术已开发数年；并解释了双光子视网膜显示器的潜在优势。

期刊介绍： Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
