Struct TotalInternalReflection 

Source 
pub struct TotalInternalReflection;
Expand description

Total internal reflection (TIR) analysis.

TIR occurs when light travels from a denser medium into a rarer medium at an angle exceeding the critical angle.

Implementations§

Source§

impl TotalInternalReflection

Source

pub fn critical_angle(n1: f64, n2: f64) -> Option<f64>

Critical angle θ_c = arcsin(n2 / n1) in radians.

Returns None when n2 ≥ n1 (TIR cannot occur).

Source

pub fn critical_angle_deg(n1: f64, n2: f64) -> Option<f64>

Critical angle in degrees.

Source

pub fn is_total(&self, n1: f64, n2: f64, theta_i: f64) -> bool

Returns true when the incidence angle exceeds the critical angle.
