Dear

Attached is a folloy-on proposal from conccrning the usa or pyrotechaic material to bring about visual incapacitation. Under a prior effort developed two pyrotechnic packages designed to produce flash blindnass with low risk of pormanent retinal damage. A copy of this final report is attachod. They had intended to establish a safety criterian and urilize in-house personnel for test and evaluation of the flash cartridges. Their management decided (justifiably so) that the risk vas too greac for human experimentation. As a consequance, the present proposal is intended to provide simulation methods by uhich one could predict the degrce of incapacitation whtch vould be-prosuced-by-che pyrowo technic cartridges developed.

I vould appreciate your evaluation of this proposal.I don't wish to prejudice your opinion, but I'ù not sure that ona could extrapolate fron the simulation data to predict incapacitation resulting fron higher light levels. Although I would like to consider your response as evidence of affort under the new coutract, please do not feel obligated to undertake, at this time, a complete evaluation of the retinal damage problem on the basis of. this proposal.

Furtheruore, there is an obligation to reopoud to this proposal ia the imsediate future. Your personal opinion or the conscnsus of your colleagues vill be sufficieut at this time. Any altcrnative suggestions will be appreciated. Also included in this package are sone DOD roporcs relevant to the problen. I would appreciate return of the material when it has served its purpose.

Sincerely,

2 November 1970
