Line laser beam production and its use in scanning densitometers |
摘要 |
An arrangement for producing a laser beam as a line utilizing a sharp straight edge intercepting a portion of the original spot laser beam. The use of an diffraction grating at varying angles of the incident spot laser beam also produces a stretched laser spot of various orders with laser lines connecting the various orders.
