Wavelengths List (Item 128).

From ST0601:

List of wavelength bands provided by sensor(s).

The Wavelengths List is a list of information used by the on-board sensors which collect Motion Imagery. This item is a companion to Active Wavelength List (Item 121).

Table 14 shows predefined sensor records which support a set of common wavelengths used by sensors. The Active Wavelength List (Item 121) can use these predefined wavelength bands if they are sufficient for the given platform’s sensors. If a platform/sensor requires more specific or customized wavelength records, this item enables their definition. Any custom Wavelengths List records are sent at a minimum of once every 30 seconds. If the predefined wavelengths are sufficient for the platforms sensors there is no need to send a Wavelengths List item.

Table 14: Predefined Wavelength Information Records

ID	Min (nm)	Max (nm)	Name	Description
1	380	750	VIS	Visible light
2	750	100,000	IR	Infrared
3	750	3000	NIR	Near/Short Wave Infrared
4	3000	8000	MIR	Mid-wave Infrared
5	8000	14000	LIR	Long-wave Infrared
6	14000	100,000	FIR	Far-Infrared

A sensor wavelength record contains a numeric identifier (ID), min/max wavelengths, and a unique name for display on remote terminals, etc. The ID is a unique number for the wavelength record. Custom wavelength records begin at ID 21 and increment as needed. A custom wavelength record persists only for a given flight. The “Min” and “Max” wavelengths define the range of the band. The “Name” is a unique string describing the band. The sensor wavelength record does not include the “Description,” it is only in the table for informational purposes.

See the Motion Imagery Handbook Section 3.1 for information on these wavelengths and descriptions.

Constructor Detail

WavelengthsList

public WavelengthsList(List<Wavelengths> wavelengths)

Create from value.

Parameters:

wavelengths - the list of wavelengths objects.

WavelengthsList

public WavelengthsList(byte[] bytes)
                throws KlvParseException

Create from encoded bytes.

Parameters:

bytes - The byte array containing the variable length pack.

Throws:

KlvParseException - if there is a problem during parsing

Method Detail

getWavelengthsList

public List<Wavelengths> getWavelengthsList()

Get the list of wavelengths.

This gets the live list, so it can also be used to add an entry, or to clear the list.

Returns:

the known wavelengths, as a list.

getBytes

public byte[] getBytes()

Description copied from interface: IUasDatalinkValue

Get the encoded bytes.

Specified by:

getBytes in interface IUasDatalinkValue

Returns:

The encoded byte array

getDisplayableValue

public String getDisplayableValue()

Description copied from interface: IKlvValue

Return a string of the displayable value.

Specified by:

getDisplayableValue in interface IKlvValue

Returns:

String representing the value

getDisplayName

public String getDisplayName()

Description copied from interface: IKlvValue

Get the human-readable name for the value.

Specified by:

getDisplayName in interface IKlvValue

Returns:

The name of the type
