Slow-light prism enhanced spectroscopy (SLOPES) is described. In one embodiment, a method for characterizing spectral properties of a sample includes illuminating a material sample by a tunable source of light. In response to illuminating the material sample, scattered light is produced, where the scattered light embodies spectral properties of the sample. Method also includes, passing the scattered light through a vapor prism cell. The vapor prism cell includes prismatic surfaces in a path of the scattered light. The vapor prism cell contains gas that is configured to selectively slow down propagation velocities at different spectral features of the scattered light and to disperse different spectral features of the scattered light at separate angles. The method also includes acquiring signals corresponding to time-gated spectral properties of the scattered light after propagating through the vapor prism cell. The acquired signals are discriminated in time based on acquired signals' time-gated properties and in space based on acquired signals' dispersion angle and subsequent location on an acquisition plane. Spectral features of the scattered light are determined based on the acquired signals.

This utility model belongs to the field of naked-eye 3D technology, and specifically relates to a combined lens, including a base plate. Multiple first horizontal grooves are formed on the top surface of the base plate, and multiple lens blocks are slidably connected within these grooves. A second horizontal groove is formed on the top of each lens block, and a lens head is slidably connected within it. The projections of the sliding directions of the lens blocks and the sliding directions of the lens heads onto the top surface of the base plate are perpendicular to each other. Furthermore, the lens head includes a cylindrical lens, a spherical lens, and a prismatic lens. Through the above configuration, this utility model allows for adaptive adjustments to the lens combination method according to actual usage needs, meeting the requirements of different scenarios, and facilitating the replacement, maintenance, and upkeep of the lens head, thereby improving the service life of this utility model.
