Abstract: A real-time wavelength correction system for visible light is co-operated with an optical system to make a parallel light beam split into a zero-order diffractive parallel light beam and a first-order diffractive parallel light beam. The zero-order diffractive parallel light beam focuses on a first back focal plane to form a first light spot. A drift of the first light spot is applied to determine an angular drift of the parallel light beam. The first-order diffractive parallel light beam is focused on a second back focal plane to form a second light spot. A drift of the second light spot is applied to determine an angular drift of the first-order diffractive parallel light beam. The angular drifts of the parallel light beam and the first-order diffractive parallel light beam, which are changed with real time temperature variation, are applied to correct the wavelength of the parallel light beam.

Abstract: A simple type dual axes optoelectronic level includes a carrier, an adjustable fixing mechanism, a level sensing device, a container cup holding a liquid, and a reflector. The adjustable fixing mechanism and the container cup are fixed at the carrier. The level sensing device is fixed at the adjustable fixing mechanism and faces the container cup. The reflector is fixed at the bottom surface of the container cup. The level sensing device provides a measuring light beam, which is refracted by the liquid surface to the reflector, and reflected back to the liquid surface by the reflector, and refracted again by the liquid surface to the level sensing device. Through the refraction effect, the level sensing device can detect two angles between the bottom surface of the carrier and the liquid surface. The dual axes optoelectronic level has advantages of simple structure, low cost and differentiating angles of two axes.
