The optical schemes of the single light barrier single photodetector, double light barriers-single photodetector and double light barriers-double photodetectors are developed and investigated. Advantages and disadvantages of these schemes are explained. Important proposals are given for the development of the optical schemes. A double light barriers-double photodetectors system measuring the bullet speed is developed. Equations describing the errors occurring in the system are derived.eninfo:eu-repo/semantics/closedAccessBulletError detectionLight barriersPhotodetectorsOpticsImpact experimentsSpeed measurementLaser applicationsMeasurement theorySpeed controlErrorsLaserArticle0002500743000022-s2.0-34548291872104910544511OpticsProjectiles; Target Detection; Ammunition
