ABSTRACT:
A method and apparatus for acoustic supervision of adjustment of a light bundle with respect to its intensity distribution in a reference plane which is at right angles to the optical axis of the light bundle. The reference plane is subdivided into surface elements. The intensity values corresponding to a rated intensity distribution are prescribed and stored for the individual surface elements of the reference plane. The intensity values for the individual surface elements respectively existing in the adjustment are successively measured in rapid cyclical succession. The intensity deviation from the prescribed intensity value is identified and stored for each surface element. The stored intensity values are read-out in slow cyclical succession and are made audible as measuring tones for the supervision of the adjustment.
