I need to detect an object up to a distance of 8 inches 3 times per second with a power budget of 0.1 mW average. I am using a VL53L0X and I have been trying to lower the power consumption without much success. Can somebody help me with this?

I have a design ready to go but it needs to work for 3 years using 4xAA alkaline batteries. My company has planned 500K pcs/yr. I would really appreciate any help with this.Thanks,AL
