Excitation light for normal light observation with wavelengths in the visible spectrum, which is output from a lamp, and excitation light with wavelengths in the infrared spectrum for exciting a fluorescent substance characteristic of being accumulated readily in a lesion are irradiated simultaneously to a living tissue, to which the fluorescent substance has been administered, through an endoscope. Fluorescence components are separated from light stemming from the living tissue by means of a separator such as a dichroic mirror, introduced to a first imaging device, and then imaged. Light components with wavelengths in the visible spectrum are introduced to a second imaging device and then imaged. Signals representing the images are subjected to signal processing, whereby a video signal is produced. For better diagnosis, two images are displayed while, for example, one of the images is superimposed on the other.

InactiveUS6992659B2Eliminates exposed seamHigh light transmittanceCathode-ray tube indicatorsNon-linear opticsInter layerHand held
An integrated enclosure / touch screen assembly. A touch screen assembly consisting of a display mechanism and optical sensor mechanism are enclosed within a single piece cover. The optical sensor mechanism consists of lens structure and optical sensor couple to the lens structure. The single piece cover includes a transparent top surface and the lens structure is embedded within the transparent top surface. The transparent top surface of the single piece cover provides an enclosure that is both dust free and waterproof.The lens structure of the single piece cover functions by columnating light across the transparent surface. The optical touch sensor is coupled to the lens structure to register contact with the transparent surface via the lens structure by detecting disturbances in the columnated light. In one embodiment, the single piece cover is constructed by embedding the lens structure directly into the transparent surface. This process forms the single piece cover and also may be used to provide various shapes for the outer edges of the cover. The single piece cover eliminates exposed seams of the touch screen assembly. Additionally, the transparent surface is disposed directly above the display without any intervening layers, thereby improving the transmission of light to the display.

A visible light spectrum and a fluorescent light spectrum are received by a variable gain solid state imaging device provided to an endoscope. The variable gain solid state imaging device can be said to lower amplification levels for easily observed visible light spectrum, and higher amplification levels for low intensity fluorescent light spectrum observation. By varying the gain of the imaging device with the different spectrums, an object observed with the endoscope is displayed with approximately similar brightness in each white spectrum. A controller coupled to endoscope system switches different light spectrum to irradiate the observed object, while controlling amplification of the image device. The endoscope provides enhanced image detail to improve diagnosis and treatment of observed abnormal objects.
