Abstract: A traffic LIDAR device is presented with an increased laser power output in compliance with the IEC 825 standard for class one-type laser systems. Increased laser emitter power output is accomplished by reshaping the emitter source output using an optical fiber which has an inside diameter greater than the minimum dimension of the emitter source. The resulting increased cross-section of the output pulse overcomes the power output limitation that would otherwise be dictated by the emitter minimum dimension.

Abstract: Apparatus and methods for characterizing biological tissues and other turbid media with normalization that serves to compensate for the effects of scattering, reflectance, and absorption are disclosed.

Abstract: A laser transmitting and receiving speed and/or range detection device has coaxial internal beam directing and receiving paths for the transmitted and received (reflected) laser energy. A sight is provided having an optical combiner which presents a projected display of the detected speed or range of a target that may be observed by the operator while aiming the device at the target. A telephoto effect is utilized in the projection of the display onto the sight such that the operator need not divert his head from the sight or refocus his eye to read the projected target speed or range.

Abstract: Apparatus and methods for noninvasively diagnosing diabetes mellitus, the prediabetic condition, and cataracts in the human (or other) body are disclosed. Diagnoses are made by illuminating ocular lens tissue with a narrow-band light source at a selected wavelength, detecting the backscattered radiation intensity at the peak of the fluorescent response, and normalizing the detected value with the intensity of its Rayleigh component. Measurements provided in this manner can be used as improved indicators of the presence or absence of certain diseases or conditions.

Abstract: A head-up display for use in an automotive or other vehicle having limited space. The optical path from display symbol generator to a collimating lens is folded to fit in a relatively compact housing. Also shown is the use of the automobile windshield as a combiner glass for the display. Corrective lenses, and in particular crossed linear fresnel lenses, are used to correct for the astigmatism introduced by the geometry of the windshield. This provides a combination of optical powers for the display lens and the windshield which has the resultant effect of projecting an image from the image source to the driver's eye. The source is a high light output array of light-emitting diodes. A microprocessor based controller for detecting the status of inputs from the automobile is shown. Data is periodically loaded into a random access memory dedicated to controlling the display.
