摘要:
An attempt has been made to evaluate the performance of the simplest type of liquid‐solid lens, i.e., a hemispherical surface between the liquid and solid. The nature of the image allowing for the effects of refraction, absorption, and mode conversion has been determined for an equally spaced object and image. It appears that the diffraction effects are the only important ones and that geometric aberration is unimportant.
