Abstract:
A commonly used logarithmic photometer chassis employs 4 cut-in diodes to convert the quasilogarithmic function to a true logarithmic function. With 4 cut-in diodes this conversion can only be completely accomplished at 5 points in the complete dynamic range. A technique was developed allowing conversion of quasilogarithmic data to true logarithmic form to 21 points over the dynamic range. The circuitry described is applicable to multiple phototubes and photographic photometry. Author
