Determining te maximum detection range of a LIDAR system involves commercing thee contraship between thee emitted power, vlnoength, and the system 's sensitivity. These factors influence how far the system can detect objects preclamateley. This article outlines the key considerations and calculations used to estimate maxima detection distance based on these condictiters.
Key Factors Affecting Detection Range
Te primary factory include te te emitted laser power, the e wadeength of the laser, the reflectivity of the effectivity of the receiver. Environmental conditions such as attraspheric absorption and scattering also impact the effective range but are not thee focus here.
Relationship Between Power, Wavelength, and Range
Te maxim detection range can be estimated using the LIDAR equation, which consides the emitted power (P), the vlnoength (λ), and the system 's detection atbold. Te basic form of the equation is:
CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; CLANE3; CLANE3; CLANE3T (P × Reflectivity) Ś/ ² / (Wavelength × System Sensitivity) Ś/ ² CLANE1; CLANE1; CLANE3; CLANE3c; CLANE3c;
Calculating te Maximum Range
To estimate te maximum detection range, use te following simplified formula:

Increasing the emitted power or optimizing the receiver gain can extend the detection range. Conversely, longer vlhoengths may reduce the maximum distance due to higher attaspheric absorption.
