The unit for making sensitivity measurements was calibrated and teats were
made in the field on actual vehicles. . Changes in' current in the lead sulfide
photo cell produced by a vehicle moving across the field of view werq'measured.
The results of these tests indicate that the cells tested have sufficient sensi-
tivity for this application.
The attached sketch shows an array of 68 miniature photo cells which is being,
proposed for a teat of principles. Two rows of 10 cells each labelled V1 and V2
provide means for determining the height of the object, at intervals, as it passes
across the field of view. The horizontal position of the leading edge of the
object is detected by rows of photo cells H1, H2, H3 etc instead of the previously
proposed slots. The use of short vertical rows of photo cells is a possible
alternative to the slot and lens system discussed in the October report.- The
lens system described there is being evaluated by means of a small lucite cylin-
drical lens element which has been made and is being tested. An evaluation of
the two systems will weigh the optical simplicity of one against the circuit
simplicity of the other as well as make a comparison of their performance.
Study has shown that the lucite light collector approach mentioned in the
previous report has serious disadvantages.
Tests are being made on the scanner which include processing the output
from the photo multiplier tube by means of a Berkeley Counter-Timer and a Digital
Recorder. The testa are meeting with some success and are expected to be useful
in the initial evaluation of recognition patterns of test images.
Circuits are being studied to provide signal level discrimination for the
photocell outputs. Because a rather large number of cells is involved, the objec-
tive is to obtain the simplest possible circuit, and transistors will probably be
used.
