Interference between IR distance sensors

I’m looking forward to automating an aircraft maintenance platform. To control the platform approach, I pretend to use two Sharp IR distance sensors (GP2Y0A41SK0F e GP2Y0A02YK0F) with different measuring ranges (to cover the global range 4-150 cm). My question is if there’s any chance of occurring interference between the beams from the two sensors. What is the minimum distance (or the method of computing this distance) at which I can place the sensors to prevent interferences? Another option would be using two sensors with different functional principles (an ultrasonic sensor and an IR sensor). However, US sensors are usually more expensive.
Thank you in advance.

Do you know where I can find more information about using multiple IR sensors simultaneously? Intuitively, I thought the risk of interference would be low since the beam angle is small. However, I wasn't able to find any information regarding that.
Thank you in advance!
