Abstract: An endoscopic imaging apparatus comprises at least one light source (1, 2, 3) configured to provide excitation signals to an imaging region via a common transmission path. Each excitation signal has one of a plurality of different colours. A controller (100) is configured to control the at least one light source (1, 2, 3) to provide the excitation signals as a repeating time-interleaved sequence that comprises at least an excitation signal of a first one of the colours and a subsequent excitation signal of a second one of the colours. A monochrome detector (80) is configured, for each of at least some of the excitation signals, to receive at least part of a respective response signal emitted from the imaging region in response to the excitation signal and to generate image data based on the at least part of the response signal.

Abstract: Disclosed are scanning devices which measure and quantify optical properties within an object such as the absorption of light, refractive index, light scattering, fluorescence, and phosphorescence. Through the use of two rotating plane mirrors and two paraboloid mirrors, a laser light beam is made to traverse the object to be scanned wherein the beam is always parallel to the optical axis. The invention provides an improvement over previously reported scanning devices by virtue of increased speed and resolution. Two-dimensional projections gleaned by each scan of the object are reconstructed into a three-dimensional image through the use of various computer techniques.
