| 181 | Digital range sensor system | US09517677 | 2000-03-02 | US06288786B1 | 2001-09-11 | Eric P. Rudd; William P. Kennedy; Troy R. Pesola; David D. Madsen |
| A digital range sensor comprises a light source, an optical element to focus the light from the source down to a small spot on a target, a second optical element that is mounted obliquely from the source axis, and a prism mounted on a multi-element detector, which in turn is mounted at the focus of the light returning from the target. The purpose of the prism on the detector is to direct the light onto the active surface of the detector at an angle closer to normal incidence than would otherwise be possible. The detector produces digital data which is transferred to a control module for processing and to produce a numerical range measurement. | ||||||

This is integrated in a rifle-like carrier with an aiming device, range finder, and a portable power supply unit.

| 189 | Chromatic optical ranging sensor | US509534 | 1995-07-31 | US5790242A | 1998-08-04 | Howard Stern; Robert J. Metzger |
| A three dimensional sensor includes an illumination source that produces broadband, high intensity optical energy. This optical energy includes a number of individual wavelength components. The individual wavelength components are impinged in a spot on a target. Dispersion is applied to the light reflected from the spot, either before target impingement, after target impingement, or both, whereby light of different colors is focused at different distances from the target. A maximum reflected wavelength, dependent on target range, is detected to determine the target range. In one embodiment, temporal modulation is applied to the light before target impingement. A stationary detector determines the target range by relating the maximum light received to the time it is received in order to determine the color received at that time. In another embodiment, all colors are reflected from the target simultaneously, and the reflected beam is chromatically dispersed in the transverse direction. A detector array, or a linear position sensor, is employed to determine the transverse position of the maximum amplitude of the transversely dispersed beam. The transverse position, being related to a particular color, contains information from which the range to the target is determinable. | ||||||
