and cracks a low power (2mW) Helium-Neon(HeNe) laser source has been used. Due to relatively high wavelength of the red photons irradiated from the HeNelaser source, the incident laser beam possesses a very high level of reflectivity and negligible penetration.The experiments listed in this paper explore unique optical methods using a line laser. The advantage for using thistype of laser is that it generates low energy red photons having about two to three electron-volt energy andpossessing perfect reflectivity. The low energy photons have negligible low penetration. The paper explains amethodology for non-contact measurement of radius of curvature on the finished surface of manufactured parts.

It continued to focus onhands-on technical education, working closely with industry through regular meetings withadvisory councils. OIT hires primarily faculty with industry experience, and continues Purvine’stradition of stressing education in communications and other non-technical subjects. It alsomaintains close ties with the ASEE and ECPD. For example, faculty at OIT led the effort to editand publish the volume of ASEE Engineering Technology history in 1995. Today, the institutionis recognizably a manifestation of Purvine’s desire to provide for “The Forgotten Generation.”Due to his contributions, Purvine was recognized as one of the

So, in many cases the most practical method of achieving this goal is to provide ashort term simulation of the industrial environment where the student can be observed and givenadvice how to proceed by an expert in the field when necessary.This method closely follows the circular experiential learning model first proposed by Lewinthen later refined by Kolb3,4. In this cycle, student learning is a dynamic that flows throughconcrete experience, reflective observation, abstract conceptualization and active experience. Inthis

This is clearly reflected in the student feedback.
