Riflescope with turret encoder controlled laser rangefinder

A weapon aiming system, comprising:

• a riflescope having at least one turret for adjusting the position of an internal reticle aimpoint;
• at least one encoder that senses a relative position change of at least one of the turret and the reticle;
• a laser rangefinder (LRF) associated with at least one pair of Risley prisms operable to adjustably position a LRF aimpoint to coincide with the aimpoint of the riflescope reticle;
• a controller;
• a motor associated with each Risley prism and controlled by the controller to position the associated prisms;
• wherein the system is configured such that adjusting the aimpoint of the riflescope reticle causes the encoder to send a position change signal to the controller programmed to, in response, direct the motors to reposition the prisms so that the LRF aimpoint continues to coincide with the reticle aimpoint.
