To heat 1 cm³ of water by 1°C, you need approximately 4.184 joules of energy, as 1 calorie is defined as the energy required to raise the temperature of 1 gram of water by 1°C, and 1 cm³ of water has a mass of about 1 gram.
So to heat your eye of 1cm3 in 1 second you need 4.2 watts of infrared to enter your eye. That sounds too much power for lidar, but couldn’t find quickly how much power is emitted by lidar though…
