C\u00f3mo Lumexis Aborda la Selecci\u00f3n de M\u00f3dulos<\/h2>\n\n\n\n Lumexis develops 1535 nm pulsed time-of-flight laser rangefinder modules for civil UAVs, surveying instruments, infrastructure inspection, remote sensing and scientific equipment.<\/p>\n\n\n\n
Our team begins with the target and operating conditions. We then review the range envelope, wavelength, divergence, receive aperture, interface, mechanical package, power demand and qualification method.<\/p>\n\n\n\n
The current Lumexis series includes 3 km to 15 km model classes, adjustable 1\u201310 Hz ranging, model-dependent TTL or RS422 communication, range gating and multi-target reporting. Model selection should still be based on the intended target and installed system rather than the model name alone. <\/p>\n\n\n\n

Preguntas frecuentes<\/h2>\n\n\n\n\u00bfCu\u00e1l es la especificaci\u00f3n m\u00e1s importante al seleccionar un m\u00f3dulo de tel\u00e9metro l\u00e1ser?<\/h3>\n\n\n\n No existe una \u00fanica especificaci\u00f3n m\u00e1s importante. Comience con el objetivo y la distancia requerida, luego eval\u00fae la precisi\u00f3n, la tasa de lecturas v\u00e1lidas, la longitud de onda, la divergencia, la apertura, la tasa de medici\u00f3n, el alcance m\u00ednimo, el encapsulado, la potencia y la interfaz como un solo sistema.<\/p>\n\n\n\n
\u00bfUn m\u00f3dulo de 10 km es siempre mejor que uno de 5 km?<\/h3>\n\n\n\n No. Un m\u00f3dulo de 10 km puede ser m\u00e1s grande, m\u00e1s pesado y m\u00e1s costoso. Tambi\u00e9n puede tener un alcance m\u00ednimo m\u00e1s largo o una apertura de recepci\u00f3n m\u00e1s grande. Elija el modelo pr\u00e1ctico m\u00e1s peque\u00f1o que proporcione suficiente margen verificado para el objetivo y el entorno reales.<\/p>\n\n\n\n
\u00bf1535 nm es siempre mejor que 905 nm?<\/h3>\n\n\n\n No. Una arquitectura de 1535 nm puede ser muy adecuada para sistemas compactos de largo alcance, mientras que 905 nm puede ofrecer opciones maduras de fuente y detector de silicio para otros dise\u00f1os. Compare el sistema completo, incluido el rendimiento sobre el objetivo, el detector, la \u00f3ptica, la evaluaci\u00f3n de seguridad, el tama\u00f1o y el costo.<\/p>\n\n\n\n
\u00bfLa Clase 1 en el m\u00f3dulo hace que el producto terminado sea Clase 1?<\/h3>\n\n\n\n No autom\u00e1ticamente. La ventana del host, la \u00f3ptica a\u00f1adida, los modos de funcionamiento y las aperturas accesibles pueden cambiar el l\u00edmite de seguridad final. El producto terminado debe evaluarse en su configuraci\u00f3n final.<\/p>\n\n\n\n
\u00bfCu\u00e1nta divergencia de haz deber\u00eda tener un m\u00f3dulo de largo alcance?<\/h3>\n\n\n\n La divergencia correcta depende del tama\u00f1o del objetivo y la estabilidad de apuntamiento. Un haz estrecho puede colocar m\u00e1s energ\u00eda en un objetivo compacto, pero tambi\u00e9n requiere mejor alineaci\u00f3n y menor error de apuntamiento. Calcule la huella del haz a la distancia requerida antes de decidir.<\/p>\n\n\n\n
\u00bfDeber\u00eda un OEM usar TTL o RS422?<\/h3>\n\n\n\n TTL o una interfaz UART local pueden ser adecuados para una conexi\u00f3n corta y controlada. RS422 suele ser m\u00e1s pr\u00e1ctico para cables m\u00e1s largos o entornos el\u00e9ctricos m\u00e1s ruidosos. Utilice la documentaci\u00f3n el\u00e9ctrica y de protocolo del proveedor para el modelo exacto.<\/p>\n\n\n\n
\u00bfC\u00f3mo deber\u00edan compararse los alcances m\u00e1ximos de dos proveedores?<\/h3>\n\n\n\n Exija que ambos proveedores declaren el rendimiento utilizando el mismo tama\u00f1o de objetivo, reflectividad, \u00e1ngulo del objetivo, visibilidad, luz ambiental, temperatura, definici\u00f3n de lectura v\u00e1lida y modo de medici\u00f3n. Sin condiciones comunes, las dos cifras de alcance m\u00e1ximo no son directamente comparables.<\/p>\n\n\n\n
Conclusi\u00f3n<\/h2>\n\n\n\n Elegir un m\u00f3dulo de tel\u00e9metro l\u00e1ser no es buscar el n\u00famero de distancia m\u00e1s grande. Es un proceso de adaptar el canal \u00f3ptico, el\u00e9ctrico, mec\u00e1nico y de software completo a un problema de medici\u00f3n definido.<\/p>\n\n\n\n
Comience con el objetivo. Defina la ventana de distancia real y el m\u00e9todo de aceptaci\u00f3n. Compare los candidatos bajo condiciones comunes. Luego valide el m\u00f3dulo con la ventana final, el montaje, la fuente de alimentaci\u00f3n, el cable y el software host.<\/p>\n\n\n\n
Este enfoque puede requerir m\u00e1s trabajo durante la evaluaci\u00f3n, pero reduce el redise\u00f1o, las fallas de campo inexplicables y la variaci\u00f3n de producci\u00f3n despu\u00e9s de que el m\u00f3dulo ha sido integrado.<\/p>\n\n\n\n
