Abstract: A distance measuring device that measures a distance to an object. The distance measuring device includes: a light source that emits pulsed light; a reflector that reflects and radiates, as radiation light, the pulsed light emitted from the light source, and reflects object light that is the radiation light reflected by the object and returning; and an imager that captures the object light reflected by the reflector. The pulsed light emitted from the light source is diffused light. The light source and the imager are located to face the reflector. The reflector radiates, as the radiation light, light in a shape with a long axis and a short axis. The imager performs exposure in synchronization with the pulsed light to image the object light.

Abstract: Method and Apparatus are provided for visibly outlining the energy zone to be measured by a radiometer, the method comprises providing a laser sighting device on the radiometer adapted to emit more than two laser beams against a surface whose temperature is to be measured and positioning said laser beams about the energy zone to identify said energy zone. The apparatus comprises a laser sighting device adapted to emit more than two laser beams against the surface and means to position said laser beams about the energy zone and to identify said zone. A primary laser beam is passed through or over a beam splitter or a diffraction grating and formed into a plurality of secondary beams which produce on the target surface a pattern which identifies the zone investigated with the radiometer. Laser light may be directed axially to illuminate the central area of the zone.

The method comprises the steps of providing a laser sighting device on the radiometer adapted to emit more than two laser beams against a surface whose temperature is to be measured and positioning said laser beams about the energy zone to outline said energy zone. The apparatus comprises a laser sighting device adapted to emit more than two laser beams against the surface and means to position said laser beams about the energy zone to outline said energy zone. The laser beams may be rotated about the periphery of the energy zone. In another embodiment, a pair of laser beams are projected on opposite sides of the energy zone. The laser beams may be further pulsed on and off in a synchronised manner so as to cause a series of intermittent lines to outline the energy zone. Such an embodiment improves the efficiency of the laser and results in brighter laser beams being projected.

Abstract: A device for the non-contact temperature measurement on an object comprises a detector device with a detector and IR optics, which image the detector along a measuring beam path with an optical axis onto a measuring spot on the object, and a sighting device for the visualization of the measuring spot with a light source for the creation of marking light and ring optics, which form a marking beam path that surrounds the outer circumference of the measuring beam path. The marking light is aligned so that on each location of the marking beam path its cross section, vertical to the optical axis, forms a circular ring surface.

Abstract: Device for contactless temperature measurement of an object with an optical system which images into the finite and a detector, wherein an image of the detector is imaged by the optical system along an optical axis onto a measurement spot on the object in such a way that the image of the detector reduces from the optical system to a sharp point measurement spot and then enlarges, and also with a sighting arrangement which identifies the outer limit of the measurement spot by means of visible sighting rays. Each sighting ray is aligned obliquely with respect to the optical axis in such a way that each sighting ray can be used both before and also after the sharp point measurement spot to identify the measurement spot.
