The wavelength tuning ranges of a grating external-cavity laser diode (ECLD) have been studied by the equivalent cavity method. The maximum tuning range (MTR) and the continuous tuning range (CTR), which are related t...
A technique of fast 360° spinning 3D measurement is realized.A laser diode used as light source produces 0.5 mm wide slit which is projected onto the surface of an object via a groupe of optical lenses.A CCD camera c...
